+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+    BUGS
+
+    - Fix crash after animation rendering
+
+      Analysis: changes introduced for sffe made the uih variable from ui.c
+      global in ui.h so that the sffe parser can be accessed from custom
+      formula code in formulas.c. Uih was previously declared static in render.c
+      because the animation renderer maintains its own context.  SFFE changed
+      this from static to extern so the uih in render.c was pointing to the same
+      uih in ui.c, instead of to a different structure.  When animations were
+      rendered, the uih in ui.h got clobbered, and the next function that tried
+      to use it caused a segfault.
+
+      Fix:
+      1. Change name of global uih pointer defined in ui.h from uih to globaluih.
+      2. Change sffe code to access globaluih pointer instead of uih
+      3. Add code to main function to set both uih and globaluih to point at the same structure
+      4. Change code in cocoa driver to use globaluih as well
+
+    - Fix bug that causes XaoS to crash when using non-native (ugly) dialog
+      code for Render Animation dialog with open file dialog for basename
+
+      Analysis: There was a loop in ui_buildfile in dialog.c, that tried to
+      find a "*" in the default filename, and if it didn't find one, it would
+      run right off the end of the buffer and continue until a seg fault occurred.
+
+      Fix: the loop now checks for both "*" or a nul terminator as the exit
+      condition.  If it doesn't find an asterisk, it still stops at the end
+      of the string.
+
+    - Make custom dialog boxes slide out of view before executing menu function
+
+      This prevents the dialog from hanging around after clicking OK during long
+      running operations such as rendering animations

+     * The Mac OS X driver requires a 32-bit rgb mask where the most significant
+     * byte is on (e.g., 0xffffff00). This exposed a bug in the interpol macro
+     * that resulted in distorted colors for the smooth coloring modes.
+     * If the interpol macro is applied to such a mask, it causes an overflow
+     * of the 32-bit int, and the left-most color byte is lost.
+     *
+     * I added shiftinterpol macro to handle such masks. It shifts everything 1
+     * byte to the right, performs the calculation, and then shifts everything
+     * back 1 byte to the left when it is done.
+     *
+     * I also created the safeinterpol macro which detects if the most
+     * signficant byte in the mask is on, and uses the shiftinterpol macro if
+     * so, or the orignal interpol macro if not.
+     *
+     * I then modified the interpoltype macro to use the safeinterpol macro
+     * instead of the interpol macro directly.

+Changes to autocof:\n1) Detect Darwin (Mac OS X) and pass -DNOASSEMBLY on CFLAGS and CFLAGS1 if found, since Apple's gcc cannot compile the assembly code in i386.c\n2)Add output of 'gsl-config --cflags' to CFLAGS and CFLAGS1.

+Hello,
+
+I am writing you about the GNU XaoS project,
+as part of by effort to help GNU projects provide a better, more
+consistent build system.
+
+Currently, your project seems to support DESTDIR variable in the
+generated Makefiles (marked as optional in the GNU coding policies, make and
+automake manual), however there's a problem that prevents DESTDIR from
+working correctly.
+
+The STICKY variable, set in configure and used in Makefile, does not consider
+DESTDIR. This can break the build if the user tries to use DESTDIR support.
+
+You can read more information about DESTDIR in the GNU coding standards
+http://www.gnu.org/prep/standards/
+
+and in the Automake manual:
+
+http://www.gnu.org/software/automake/manual/html_mono/automake.html
+
+Sections: "When automake is not enough" and "Staged installs"
+
+I am ready to offer you additional information, help and support.
+Thank you for your help in making GNU projects build systems better.
+

+
+Sure thing. I attach a patch against version 3.1 that
+does the following:
+
+configure.in: add DESTDIR to STICKY variable.
+Makefile.in: run -@STICKY@ to ignore chown, chgrp etc
+ useful when running non-root DESTDIR installs.
+ Also strenghten info pages installation rule,
+ avoiding bug that happens when $(infodir)
+ does not exist (see GNU coding standards,
+ never use a directory as the second argument of
+ install)

+3 small patches by Philippe Wautelet <p.wautelet@fractalzone.be>,
+sent to me on Tue, 26 Oct 2004 22:44:12 +0200:
+
+-----------------------8X-------------------------------------------------
+Hi,
+
+Here are the patches to correct some (small) bugs I found.
+
+filesel.patch: correct a bug in the list of files in a directory: a
+negative value could appear (the check was done too early) and was at
+the origin of an access out of the valid memory range
+
+ui.patch: correct a bug when the -nogui option was used and that there
+are no available driver (this corrects the bug with the request ID 906942)
+
+zoom.patch: permutated some conditions in 'if' to prevent access to not
+initialized values
+
+That's all for the moment.
+
+Regards,
+
+Philippe
+-----------------------8X-------------------------------------------------
+
+I compiled the code after applying the patches and no problems occured
+during running (however I didn't do big tests, including the original
+problems, too).

+::::::::::::::
+ChangeLog
+::::::::::::::
+Version 3.1
+	o New homepage at http://www.gnu.org
+      Speedups:
+        o The internal loop now uses integer comparisons on x86 (about 10%
+	  speedup)
+	o Better timming
+	o Cleverer and faster solid guessing algorithm
+	o Faster resolution reduction loops (more cache and SMP friendly)
+	o Faster copying loops (lower register pressure because of new table
+	  layout)
+	o New string inlines for x86 that does aligning of memory acceses
+	o I've made some patches to gcc-2.95 to improve XaoS code
+	o Assembly loops for moving data
+	(overall XaoS is more than twice the speed of version 3.0)
+      New features
+        o New antialiasing filter
+	o New drivers:
+	    GGI
+	    DGA
+	    Win32
+	    dX-window
+	    dX-fullscreen
+	    BeOS
+	    DirectWindow
+	    DirectScreen
+	o Improved tutorials:
+           o New tutorial "math behind fractals"
+           o First chapter of tutorial "an introduction to fractals" has been
+	     split into the introduction part and part about the Mandelbrot set
+	   o Improved first chapter
+	   o Added line graphics into many tutorials
+	   o Spanish message catalog contributed by Cesar Perez
+	o Added (color) command to specify color of text
+	o Rendering sequences of images from animation files
+	o New wrapper around I/O routines alowing XaoS to read arbitary streams
+	  like string etc.
+        o New library for handling menus added. I think it is big step towards
+	  a nice user interface, since all keybindings and menus will be
+	  independent at UI, so the ugly interface now will be just simple code
+	  calling this library. 
+	o Added simple dialog description structure...
+	o Added library with simple graphics primitives (line, rectangle,
+	  text)
+	o Palette extended to allow few preallocated color cells for UI and
+	  such.
+	o Timer library now handles current group changes nicely,
+	  also supports time emulation used by emulating constant framerate
+	  good for saving animations
+	o Palette creator now accepts zero for maximal palette size
+	o Lots of play functions made generic and integrated into user
+	  interface (user now should specify palette seed or reset state
+	  of XaoS into "factory defaults")
+	o Menus, dialog, command line options, hotkeys and animation replay
+	  code now use same function registry. So there are lots of new command
+	  line parameters, file format commands etc...
+
+	  Some command line parameters also changed their name (like -load ->
+	  -loadpos) so please modify your scripts...
+	o Added xshl (XaoS simple hypertext langage) library
+	o Motion blur now handles changes of filter configuration in better
+	  way
+        o Added some other fractal examples into first chapter
+	o Behave better when btrace or interruptible calculation interrupted
+        o Documentation split into Hacker's and User's guide, so we don't need
+	  to distribute hacker documentation in the source distributions and
+	  users don't need to print this part.
+	o Timer library now supports Win32 high precision timer
+	o Support for backslash path convention under DOS and Windows
+	o Accept both \n lines and \n\r lines
+        o Internationalization (i18n) support added for menus
+        o New fractal types: newton^4, barsnley2 and magnet2
+      UI changes:
+	o Menus are now displayed nicely
+	o New nice dialogs. XaoS is now mostly user friendly :)
+        o Native UI wrappers for BeOS and Windows
+	o Undo and redo, cut and past available at many systems
+	o Main menu is now available at 'enter' key.
+	o Better arrow keys handling
+	o Formula changing now resets perturbation too
+	o New context sensitive help. 
+	  Now uses xshl (XaoS simple hypertext language), so you
+	  might do hyperlinks, links to tutorials and basic formating of text
+        o Bailout may be set
+        o Logarithmic zoom ratio also displayed in ministatus
+      Driver API changes
+	o Drivers now sends special keys as KEY_UP etc...
+	o Parameter parsing library cleaned. It now don't prints driver's
+	  name automatically in help text. Use HELP line. (see ui_template.c)
+	o Removed TRUECOLORMI, HICOLOR and REALCOLOR image types.
+	  There is now just TRUECOLOR16, TRUECOLOR24 and TRUECOLOR.
+	  to set where red, green and blue channels lie use new redmask,
+	  greenmask and bluemask fields in driver's structure
+	o Similar changes in the S* configure defines
+	o Removed unused functions: driveropt (now should be done by menus)
+	  clrscr (now XaoS does in the buffer)
+	o Added new flag RESIZE_COMMAND
+	  (if ui should add an '=' resize function to menu - should be enabled
+	   in the most fullscreen drivers, which don't do resizing dialog
+	   using menus, but using getsize call - like SVGAlib etc.)
+	  windowed drivers should disable this
+	o Removed help entry (add this text into xaos.hlp file with same
+	  keyword as your driver's short name)
+      UI-helper changes:
+        o It is now based on a menuing system... controls are almost the same,
+	  but internally implementation is different. Only visible changes I
+	  know about are that double 'q' for quit doesn't work anymore, and 's'
+	  menu is now like the file menu in many programs, so it contains quit and
+	  other functions.
+	o window handling
+	o New message and error handling code 
+	o Displays texts directly to output buffer instead of asking
+	  ui interface
+	o Improved passfunc
+	o Support for constant framerate emulation
+      Fixes:
+        o Support for libpng 1.0.x and 1.1.x
+        o Fixed email addresses in ANNOUNCE
+	o Fixed nasty bug in timer library - it caused great memory
+	  corruption..
+	o Fixed crash in palette filter
+	o Fixed some memory leaks
+	o Color cycling don't overwrite filter's palette anymore
+	o Fixed memory leak in blur.c
+	o Enabled forgotten optimizations for bpp==1
+	o Removed IMO unusable command (calculate)
+	o Fixed memory leak in error handling in play.c
+	o Check for inconzestient configuration in ui_helper.c
+	o play now accepts empty files
+	o cycling speed is saved correctly
+	o Filters are now saved in right order, filters that depends
+	  at master are initialized first.
+        o No crash when user tries to set letterspersec to 0,
+	  it's not allowed now
+        o Fractal type magnet has been modified
+      Cleanups:
+	o Removed lots of ui code and moved to menu.c
+	o Removed old and obsolete functions ui_message, ui_tbreak, ui_menu
+	  ui_message2 renamed to ui_message
+	o Removed ui_tbreak calls from x11 driver
+	o Removed curses driver - it is obsoleted by aa driver now
+	o Structure timer moved to timerlib...
+	o Removed ui_getcontext, since it is old and ugly hack to give
+	  better control to driver not recommended at all...
+	o Removed special driver menu code and integrated into XaoS menuing
+	  system
+	o Removed some code duplication in uinew
+	o Removed old keyboard buffer code in uinew.c
+	o Assertions are now disabled in zoom.c
+	o ui and ui-helper split into separate directories
+	o uinew renamed back to ui. It is not so new anymore :)
+	o many rewrites in ui code. 
+	o Engine now handles generic truecolor modes at depths 16,24 and 32
+	  (not just few selected ones)
+	o The full code has been autoformatted with GNU indent utility
+      X11 driver:
+        o better support for bitmaps
+	o Added windowid option to support external GUIs
+	o Extended visualid detection heuristics
+	o Avoided crash when selected visual != default visual
+	o Now supports almost all truecolor modes...
+	o Take care for incompatible endianity of images
+      Svgalib driver:
+        o Use linewidth parameter instead of bytesperpixel*width
+	o Send correct key masks
+	o -grayscale for grayscale emulation
+      AA-lib driver
+        o Uses new menuing system
+-------------------------------------------------------------------------------
+Version 3.0
+      MOST SIGNIFICANT CHANGE:
+	o Richard M. Stallman agreed with adding XaoS into GNU project
+      Fixes:
+	o XaoS is now sticky bit save when svgadriver enabled
+	o Fixed crash in resizing in stereogram mode
+	o Fixed crash in stereogram mode+different scanline/width
+	o Fixed crash with dealing NaN sizes
+	o Fixed small bug in mkrealloctable
+	o Fixed ctrl87.c to do not make compilation problems anymore
+	  (was renamed to i386.c :) but also some register conflicts fixed.
+	o Fixed memory owerflowing in julia code
+	o Removed GIF code due to patent problems
+	o Timer library and ui code now handles better low resolution timers
+          Also measuring of time for status line changed. So gives bit
+          different results now :) (lower but more exact)
+	o Fixed few minnor bugs in solid guessing. Now it should be
+	  more effective. But who knows...
+	o -incoloring now works
+      Major code reorganization. 
+	o New palette functions supports
+	  x truecolor, truecolor24, hicolor and maxcolor handling
+	  x allocation/set palette scheme
+        o New nice image structure that suppotrs:
+	  x truecolor, truecolor24, hicolor, maxcolor, and 256 colors
+	  x nonstandard order of lines (like one in windoze etc..)
+	  x double buffering
+	  x palette functions
+	o New partially object oriented filter sistem 
+	  x allows elegant way to add effects like stereogram generation
+	  x makes possible to reduce resolution after stereogram etc..
+	  x combination of various calculation algorithms is now 
+	    possible in elegant way
+	  x makes source code much cleaner and extensible
+	o New user interface helper library 
+	  x makes easy to add new user interfaces or use as
+	    a part of some other program
+	  x implemented in cleaner way than old ugly-interface
+	  x hides XaoS's internals and provides easy to understand
+	    set of functions for users of XaoS engine.
+	o XaoS now uses center/range possitioning instead of
+	  left top/right bottom becase:
+	  x it is better human readable (you can see zoom easily)
+	  x it is more exact (small difference do not fall to zero
+	    as soon as in normal system)
+	  x it is easier to handle in rotation (you can do still
+	    same operations - zooms, movements like in unrotated.
+	  x better fits operation permited in(zooming view/moving)
+	  x I expect will look better in save files
+	  x simplified many operations performed on it.
+        o As the side effect:
+	  x old ugly interface code is a bit obsolette. Requires 
+	    small changes into drivers
+	  x no more large zoom_context. Context is now divided into 
+	    many parts. So many structures should be used by other
+	    parts of XaoS separately.
+	  x zoom.[ch] splitted into fractal routines and zooming 
+	    engine. This makes easier add ingnew zooming/calculation
+	    methods (like on in fractos, boundary detection...)
+	  x most of siggnificant data structures are copied into fixed 
+	    memory locations before start of calculation. I expect it 
+	    will speed up accesing its field because complex 
+	    traveling throught pointers will be avoided and reduces
+	    number of parameters passed to calculation functions.
+	    At the other hand it should bring many problems in 
+	    multithreading. In calculating one image at many procesors 
+	    should be OK. Since these structures are same. Calculating 
+	    of multiple images at time should be real problem. But why
+	    not use multitasking? or some hack with redefinig this
+	    structures back into pointers should be possible in this
+	    cases.
+	  x less multiplyings but more memory accesses in 
+	    calcline/column should speedup on pentiums with fast 
+	    cache.
+	  x autopilot now should work at many contexts at time
+	  x better implementation of fill
+	  x many new bugs but few old fixed
+	  x ugly interface code was greatly simplified since everything
+	    interesting went into ui_helper
+	  x resizing and such stuff is now much simplier
+	  x palette rotation implemented in cleaner way. Now does
+	    not require changes into drivers. Uses new setpalette
+	    driver function. I can not imagine hardware, where
+	    setpalette is imposible but rotation possible.
+	  x timer library now passes userdata to handlers - required
+	    for implementation of rotatepalette
+	  x palette rotatin in truecolor modes is not possible anymore
+	    (since xaos is not internally 8bit)
+      Cleanups:
+	o New macro system for formulas that allows easy manipulation 
+	  with calculation loops. But looks ugly. Is that cleanup?
+	o Julia code is now automatically generated for formulas..
+	o Directory structure,
+	  XaoS divided into several libs (engine,ui,util,drivers)
+	o Simplier configuration headers
+	o timerlib:wait mechanizm has obsoletted by much better slowdown
+	   mechanizm
+      Speedups:
+        o Boundary detection for new images
+        o I've browsed mkrealloctable and removed few unnecesary
+	  ifs. Maybe it speeded up..
+	o MAGICAL VALUE OF 100 FPS IS GONE!!!! Now you can see 120 FPS
+	  on pentium :)
+	  New completly fixedpoint mkrealloctable performs very well!
+	  (isn't that cool idea? just simple precalclate everything into
+	   fixedpoint that depends on the zoom and do rest in 
+	   integers ? :))) I am so silly coder! now XaoS usually does
+	   not fall under 7fps on my 486 so it works in acceprable
+	   performance. maybe we should add logo "Ready for 486!(tm)"
+	   :) (and whats about fixed point calculation loops? :)
+	   Fixedpoint brought many advantages - precalculated pow 
+	   tables, no owerflowing/NaN/precisity problems, many 
+	   variables changed to constants(since distance between 
+	   lines is statically 512) and much more :)
+	   Now we should start thinking about deepzoom feature
+	   since most of XaoS is already resolution independent.
+	   New mkrealloctable is approx twice as fast on pentium
+	   (tests on 486 should be interesting)
+	o Dynamical resolution lowering now performs much better
+	  (Should help especially on 486)
+	o Better dynamical resolution timeout choice - keeps
+	  higher framerate during zooming but lowers after
+	  zooming stops.
+        o At 386 uses uptimized versions of memset and memcpy
+	o A bit faster julia calculation loop
+	o Autopilot code is now simplier, faster, has better out of
+	  range and lowqualitty detection and seems to have better 
+	  results
+	o Macro system in calculation loop caused instant speedup. Why?
+	o New new possition caluclation algorithm. Seems to be a bit faster
+	  and produces better results
+	o Random dot generator now reduces resolution to 1/4, 
+	  because brain is unable to decode image inormations at 
+	  normal resolution. :)
+	o New uncompressed loops - one iteration for mandelbrot is 
+	  just about 14 instructions (was 23)
+	o Periodicity checking
+	   Fabrice Premel <premelfa@etu.utc.fr>
+	o Another 1/8 speedup caused by forcing register allocation 
+	  (i386 only)
+	o Malloc/free is now called less often (once per frame)
+      New features:
+	o BeOs driver. 
+	   Jens Kilian <jjk@acm.org>
+	o Truecolor(24/32-little and big edian), Hicolor, Realcolor, Fixedcolor
+	  and monochrome support
+	o Interlace filter that instantly makes your computer
+	  twice as fast!
+	o Motion blur filter
+	o Dithering filter
+	o Julia preview for all formula types
+	o Image rotation
+	o New AA-lib driver that does high qualitty text mode rendering
+	  see AA project homepage at http://www.ta.jcu.cz/aa
+	o Two edge detection filters
+	o Palette emulation filter
+	o Emboss filter
+	o SMP support using threads
+	o Two new palette generation algorithms
+	o Changed default window size to 480x360 because I hope that XaoS
+	  is now fast enought to work in resonable speed at this resolution
+	o Animated tutorials:
+	  Introduction to fractal
+	  features overview
+	  whats new
+	o New outcoloring modes:
+	  o Potential
+	  o Another colorfull decomposition
+	  o Smooth (for truecolor/truecolor24/hicolor/realcolor displays)
+	o New incoloring modes
+	  o decomposition-like
+	  o real/imag
+        o Save images into PNG format. Problem is that now XaoS 
+	  requires zlib and pnglib that should bring problems to 
+	  users compiling XaoS at UNIX workstations. I personally
+	  dislike writing of image saving code. Please if you have 
+	  some, or you want to write code, that don't require these 
+	  libraries, let me know.
+	o Saving of possition.
+	o Documentation is now in texinfo format. Describes some XaoS
+	  internals
+	o Timer library: 
+	  x handler should remove its timer when activated
+	  x New slowdown, stop and resume functions
+	  x Runtime switching between allegro compatible mode and
+	    uclock mode
+	o Configure script now does simple autodetection for long
+	  double - enables it just at intel compatible platforms, since
+	  it is sure, that it works well there. Let me know about other
+	  platforms with fast working long double
+	o New file README.compilers, that discuss optimizing
+	  switches/problems with various compilers/platforms.
+      UI Changes
+	o added -delay option as suggested by Johan Hagman
+	o added -maxframerate option that is similiar to -delay
+	o added -letterspersec option to changes subtitles speed
+	o added -threads command line option
+	o added menu for saving
+	o added .XaoSrc file
+	o new -play, -load, -letterspersec options
+	o major rewrite
+	o 'E' now handle filters (not just stereogram)
+	o 'O' now handler image rOtation
+	o 'B' for perbutation
+	o Help should be paged using up and down arrow
+	o 'S' now have menu for various saving options
+	  also during animation recording 'S' menu contains some special
+	  commands like clearing of sceeen or text ourput primitives
+        o 'V' now handles "various stuff menu" - menu with not so often used
+	  thinks. So 'K' 'G' 'T' and 'D' are free again :)
+	o Palette rotation renamed to color cycling to reduce confusin
+	  with image rotation. So it is activated by 'Y' now.
+	o Julia mode is not disabled after keypress.
+	o Configuration file
+	o Drivers now provides information about textwidth and function
+	  to clear screen
+	o New timming code allowing better replay at different
+	  resolution/computer
+	o dynamic time for dynamic resolution (nice feature :) now works 
+	  better on architectures with unexact timming(like dos with 
+	  old timming routines)
+      PLAN9 Changes
+        o Updated driver to work better with new user interface code,
+	  some cleanups
+	o -nopalette switch is now handled better - XaoS enables dithering
+	  so output is almost identical to user palette mode. Just it is a bit
+	  slower and requires more memory.
+	o Removed mkfile, since it became obsolette because of source
+	  code reorganization. I am still unable to write mkfiles since
+	  some required files seems to be missing in "demo" installation
+	  so back to mk script :(

+	o works on alphas and other 64bit architectures in 
+	   hicolor/truecolor mode Alexander V. Lukyanov 
+	   <lav@video.yars.free.net>
+	   (this change is now obsolette since hicolor/truecolor is in
+	   the main engine now)
+	o removed some XFlush calls so XaoS is now MUCH faster, but should
+	  make problems at old servers. Use -sync
+	o Fixed resize and keysym crash
+	o Supports truecolor, missordered truecolor, hicolor, realcolor and fixedcolor
+	o Uses private colormap as default since shared colormap looks

+	  but features are bit limited)
+	o added -display switch
+	o Now have normal, wait and replay mouse
+	o Handles keyboard better.
+	o Reduced memory usage in X11 modes
+	o Support for black and white modes

+-------------------------------------------------------------------------------
+Version 2.2
+      Fixes:
+	o bug in palette changing code
+	o more detections for various curses versions
+	o small well hidden bug in reallocation algorithm discovered.
+	o removed passing in registers to avoid compiler bug
+	o now allows unzoom greater than MAX_INT again
+	o symetry handling works for deeper unzooms too.
+	o more test for owerflowing/underflowing of resolution.
+	  so now produces garbage but does not crash(feature?)
+	o more exact zooming/unzooming
+	o better framerate handling
+	o fixes for pgcc - do not generate faults..
+      Cleanups:
+	o char * -> unsigned char *
+	o mkrealloctable
+	o some optimizations for pipelining
+	o cleaned code to compile with -pedantic -traditional -Wall
+	o ugly interface-better menu code, drawing fractal etc..

+	o Minor changes in color indexing
+	o palette changing code
+	o rewrote solid guessing
+	o some variables in drivers structure changed to flags
+      Speedups:
+        o symetry handling code in mkrealloc table optimized a bit.
+	  now is faster,shorter and does better job. :)
+	o non x/y symetries disabled because they slowes down for now..
+	o approximation algorithm optimized-lots of memory accesses 
+	  avoided-great speedup..
+	  now performs much better(16fps -> 18 on 486)
+	  also small hidden bug discovered, pricing redesigned a bit
+	  and loops simplified-divided into more loops
+	  function is now longer.
+	  Also taken special care to minimize number of PRICE calls
+	  mkrealloc tables is not main problem anymore. Handles
+	  correctly all situations I tryed and is quite fast.
+	o approximation algorithm is now fixed point
+	  sprprisingly very small speedup..(but much smaller code)

+	o created timer library that allows nice timing. 
+	  asynchronous operations and lots of other funny stuff..
+	  Bad thing is that XaoS does not work anymore w/o function for

+	  required
+	o approximation algorithm now works well with new 
+	  calculatenewinterruptible
+	o improved palette changing
+	o Improved solid guessing for variable range instead of range 2
+	  also another special loop w/o sg when sg impossible

+	  (is this reilable?)
+    SVGA changes:
+        o Waits for retrace before displaying..looks better
+    curses changes:
+    	o Use capital letter for G and E to avid collisions with ugly

+Version 2.1
+        o >>>>FINALLY<<<< discovered and implemented PROVED TO BE 
+	  OPTIMAL dynamical aproximation algorithm in linear time!!!
+	  It is still bit slow..but it is here!
+	  It should slow down at the begining but certainly speeds up
+	  during zoom
+	  Also allows deeper zoom
+	o added out of memory checks to make xaos safer on non unix platforms
+        o autopilot is now timed by same way as all other parts are.
+	  Now will act same on all computers(I hope)
+	o Memorry corruption bug fixed - it caused problems with ysizes not dividable
+	  by 2 with some other strange situations.
+	o New README.interface
+	   This helps others to extend XaoS or use its routines
+	   in their software

+        o private colormap support
+	o Fixed freed memory accessing bug..
+	o added switches:
+	   -private
+	   -usedefault
+	   -nomitshm
+	o improved autodetection of best available visual-if defaultvisual!=pseudocolor
+	  try truecolor first..do not use truecolor visuals on pseudocolor displays(look
+	  ugly)
+	  also supports 8bpptruecolor, staticcolor and grayscale(untested)
+	o Fixed bug in changing number of entries that caused problems on SGI
+-------------------------------------------------------------------------------
+Version 2.0
+        o Configure script.
+	o Added biomorph outcoloring mode
+	o Compiles now with -O2 - no -O3 required..

+	  256 color fractal zoomer with text based output? :)
+	o Now just one compact binary for all available drivers
+	o Faster startup..(three times)
+	o Compiles w/o many warnings(except these in libraries and
+	  implicit definitions) with -ansi -pedantic -traditional -Wall
+	o Autopilot not detects "oscillating" and too deep zoom so it can work
+	  to infinity...can run as demo w/o any user input..
+	  also auto detects major changes done by user and reinitializes variables...
+	  so it restarts after changing of fractal type and so on..
+	o many many new bugs!
+	  But remember! Its not bug! Its feature!
+   Ugly interface changes:
+        o Completely redesigned-hardware depended parts are now
+	  coded as drivers with common interface-easier adding
+	  of new architectures
+	  but looks as ugly as in previous releases :)
+	o Added changing of display driver on the fly
+	o Displays calculation status
+	o Possibility of interrupting calculation
+	o Reduced size of output program
+	  (for example SVGAlib version from 48 to 37)
+	o speed changing is now with displaying of status..
+	o all ports modified for new interface
+	o better status informations
+	o new keys:
+	  '?'/'/' status information
+	  'r'     recalculate
+	  'z'     interrupt
+	  'v'     driver change
+	  ' '     Redraw screen(or display current calculation status)

+	   -mode to select graphics mode
+	o Now handles text in xmodes w/o seg. faults
+	o Fixed possible crash after resizing
+	o for compatibility with old SVGAlib keeps old non event handled
+	  keyboard interface....but not recommended at all!
+   PLAN9 port changes:
+        o During porting to new ui interface I found nasty bug in displaying.
+	  Now plan9 port is IMWHO surprisingly fast. 8c produces quite good code.
+	  still crashes in higher resolution and has color problems
+	o added keys [,] for changing iterations and ;,' for speed
+	o Better palette handling
+   MS-DOS port changes:
+   	o Keys are now buffered-no more problems with disabling

+	o realloc_t - most often used array is now 32byte aligned..
+	o Better newton calculating code-math now optimized by hand.
+	o Small fixes in symmetry handling code
+	  also minor speedups
+	o Mandelbrot calculation rewrote into 386 assembly..
+	  less than 5% speedup :((( (gcc guys:good work! :)
+	  note that this is only for Intel platforms-xaos is still
+	  compatible with non Intel computers :)
+
+	  because of out coloring bugs disabled for now..
+	o Completely new reallocing algorithms. Now proved to be 
+	  optimal
+	  but because of ugly looking results returned back to original one
+	  current algoritmus is just about 20% slower than hypothetical
+	  optimal one..still trying :)
+	o Assembler fast inlined memcpy...also just for 386+
+	o Changed solid guessing method so it is up to 20% more effective
+	  in hope that no more mistakes introduced
+	  startup speed on 486 was reduced from 6 seconds to 4
+	  in fact it seems to make less errors than previous one :)
+	o Small changes in Barnsley code
+	o Minor fixes in symmetry code

+HOW TO COMPILE AND INSTALL XAOS
+===============================
+
+NOTE: This is the source code package for XaoS. You cannot use XaoS from 
+this package until you compile it.  For end users, we recommend using a 
+pre-built binary instead. 
+
+If you would like to install a binary version for Windows or Mac OS X, 
+download the appropriate package for your operating system from 
+
+ http://xaos.sf.net
+
+For Ubuntu and Debian users, type the following from a shell prompt to 
+automatically install XaoS:
+
+ sudo apt-get install xaos
+
+For other GNU/Linux users, refer to your distribution's instructions for
+installing packages from its repositories.  
+
+Compilation from source is only necessary if:
+
+ * you are a packager for an operating system distribution,
+ * you want to try new features which are not yet included in the
+   binary packages available for your distribution,
+ * you want to try some changes/enhancements on XaoS source code.
+
+You should be comfortable compiling software and working on a Unix command
+line before attempting these instructions.
+  
+
+
+Unix-Like Systems
+=================
+
+Build Requirements
+------------------
+
+XaoS should compile on most modern Unix-like systems.  It has been most
+recently tested on Ubuntu 9.04.
+
+The dependencies are broken down by the functionality that requires them. If 
+you are not trying to compile an official binary and only want to test or
+develop a certain subset of XaoS's features, you can skip the dependencies
+that are not relevant to those features.
+
+To compile XaoS you need:
+
+ * A modern version of gcc (3.x or higher) from http://gcc.gnu.org/
+ * Other optimizing C compilers may work but have not been tested
+
+To build the X11 UI, you need: 
+
+ * Xlib library and headers from http://www.x.org/.
+
+For the GTK UI you need:
+
+ * GTK+ 2.x (tested with 2.16) from http://www.gtk.org/.
+
+XaoS can display fractals as high quality ASCII art. For this, you need:
+
+ * AA-lib 1.4 or higher from http://aa-project.sf.net
+
+To compile XaoS with support for saving images you need:
+
+ * zlib from http://www.zlib.net/
+ * libpng from http://www.libpng.org/pub/png/libpng.html
+
+To use internationalization (i18n) you need:
+
+ * gettext from http://www.gnu.org/software/gettext/
+ * libiconv from http://www.gnu.org/software/libiconv/
+
+To support user-defined formulas, you need ONE of the following:
+
+ * nasm from http://www.nasm.us/
+ * gsl from http://www.gnu.org/software/gsl/
+
+ NOTE: Nasm will only work on x86 architectures, but GSL should work on any
+       modern platform.
+
+These dependencies may be available pre-compiled through your operating
+system's package repository.  See your operating system's documentation for
+more details.
+
+NOTE: Many GNU/Linux distributions separate the run-time and development
+components of their libraries into different packages.  If you install
+these dependencies from your distribution's repository, please make sure to
+install the development packages as well (usually marked -dev or -devel).
+
+Users of Ubuntu and Debian can automatically install all the necessary 
+build dependencies from above by typing:
+
+ sudo apt-get build-dep xaos
+
+However, GTK+ is not configured as a build dependency yet, so you will
+need to install it manually by typing:
+
+ sudo apt-get install libgtk2.0-dev
+
+
+Building XaoS
+-------------
+
+To build XaoS, type the following commands from the XaoS source directory:
+
+ ./configure
+ make
+
+XaoS will automatically detect which dependencies you have installed and
+configure itself to support whatever features are available.  If you find
+that some feature is missing, please verify that you have installed the
+corresponding dependency (including the developer libraries).
+
+Configure will try to choose the best optimization switches for your
+architecture, but it may not work well for less common ones.  You can 
+provide optimization flags by specifying them before running configure:
+
+ CFLAGS=(your best optimizing switches)
+ export CFLAGS
+
+You can also customize what optional features to build by passing options
+to the configure script.
+
+To enable experimental SMP support use:
+
+ --with-pthread=yes
+
+To enable the experimental GTK UI, use:
+
+ --with-gtk-driver=yes --with-x11-driver=no
+
+To enable the aa-lib driver, use:
+
+ --with-aa-driver=yes
+
+Run "./configure --help" for a full list of options.
+
+Once you have successfully compiled XaoS, type the following to install it:
+
+ sudo make install
+
+
+For Win32
+=========
+
+Build Requirements
+------------------
+
+XaoS supports Windows XP or later.  To compile a fully-featured XaoS binary
+on Windows, you need the following dependencies.
+
+The dependencies are broken down by the functionality that requires them. If 
+you are not trying to compile an official binary and only want to test or
+develop a certain subset of XaoS's features, you can skip the dependencies
+that are not relevant to those features.
+
+To compile XaoS, you need:
+
+ * Cygwin from http://www.cygwin.com/
+
+ In addition to the Base packages, the following packages are required:
+
+   autoconf gcc make gettext gettext-devel subversion tidy
+
+ The following packages are are also recommended to make Cygwin nicer to use:
+
+   indent mintty ncurses unzip vim wget
+
+ Any dependencies required by these packages will be automatically selected
+ when you select the package.  Do not unselect any of the dependencies that
+ the installer automatically chooses.
+
+ HINT: These packages will be easier to find if you maximize the Cygwin
+       installer and click the View button until you reach "Full" mode to
+       list the packages in alphabetical order.
+
+To build with DirectX support you need:
+
+ * DirectX SDK from http://msdn.microsoft.com/en-us/directx/aa937788.aspx
+
+To build with online help support you need:
+
+ * HTML Help SDK from 
+                http://msdn.microsoft.com/en-us/library/ms670169(VS.85).aspx
+
+To compile XaoS with support for saving images you need:
+
+ * zlib binaries from http://gnuwin32.sourceforge.net/packages/zlib.htm
+ * libpng binaries from http://gnuwin32.sourceforge.net/packages/libpng.htm
+
+ Download the installer for each labeled "Complete package, except sources"
+
+To use internationalization (i18n) you need:
+
+ * libiconv binaries from http://gnuwin32.sourceforge.net/packages/libiconv.htm
+ * gettext binaries from http://gnuwin32.sourceforge.net/packages/gettext.htm
+
+ Download the installer for each labeled "Complete package, except sources"
+
+To compile XaoS with smp support you need:
+
+ * Pthreads-w32	from http://sourceware.org/pthreads-win32/
+
+ NOTE: Pthreads-w32 will extract to the current directory by default. The
+       recommended installation path is C:\pthreads-w32.
+
+To build the XaoS installer you need:
+
+ * NSIS from http://nsis.sourceforge.net/
+
+
+Preparation
+-----------
+
+After running the installer for each of the dependencies above, start Cygwin
+from the icon on your desktop or in your start menu.  For a nicer shell, start
+MinTTY from the start menu (assuming you installed it). You will be presented
+with a bash command prompt very similar to GNU/Linux or Unix.
+
+Extract the XaoS source files:
+
+ tar xfz XaoS-$VERSION.tar.gz   # replace $VERSION with actual version
+
+Or, check out the latest sources from Subversion:
+
+ svn co https://xaos.svn.sourceforge.net/svnroot/xaos/trunk xaos
+
+NOTE: If your Windows username contains spaces, do not extract the sources in
+your home directory.  Instead create a directory called, for example, /build
+and extract them there.
+
+The remaining steps should be performed from the root of the XaoS sources.
+
+Add the contents of cygwin_profile from the tools directory to your profile:
+
+ cat tools/cygwin_profile >> $HOME/.bash_profile
+
+Edit the "$HOME/.bash_profile" file and make sure all the *_HOME variables at
+the top point to the correct location where you installed each of the 
+dependencies.  These variables are necessary so that gcc can find the 
+libraries and header files that you installed to various locations on your 
+computer.  You should not have to modify the second half of the file.
+
+Exit and restart Cygwin so the changes to your .bash_profile will take effect.
+
+
+Building XaoS
+-------------
+
+To build XaoS, type the following commands from the XaoS source root:
+
+ ./configure
+ make
+
+XaoS will automatically detect what dependencies you have installed and
+configure itself to support whatever features are available.  If you find
+that some feature is missing, please verify that you have installed the
+corresponding dependency and that the installation location is specified
+correctly in your "$HOME/.bash_profile" file.
+
+To build the windows help file go to the help directory and run the following
+command:
+
+ make chm
+
+To install XaoS to a staging directory, type the following commands:
+
+ export DESTDIR=<installdir>
+ make install-win
+
+where <installdir> should be the absolute path of the folder in which XaoS 
+should be installed.
+
+To build the XaoS installer, install XaoS to
+XaoS/src/ui/ui-drv/win32/installer/XaoS. Use NSIS to compile the script XaoS
+Installer.nsi in the directory XaoS/src/ui/ui-drv/win32/installer.
+
+
+Mac OS X
+========
+
+Build Dependencies
+------------------
+
+XaoS runs on Mac OS X 10.4 or later but compilation has only been tested 
+recently on 10.5.
+
+Xcode 3.0 or later is required to compile XaoS for Mac OS X. You can find 
+it on the Developer Tools disc that came with your computer or download it
+from:
+
+ http://developer.apple.com/mac/
+
+Pre-compiled binaries for additional Mac OS X third-party build dependencies
+can be downloaded from:
+
+ http://downloads.sourceforge.net/sourceforge/xaos/xaos-thirdparty-cocoa-20090714.tar.gz
+
+Exract this file within the src/ui/ui-drv/cocoa/thirdparty directory of your
+XaoS source distribution.
+
+Alternatively, to compile third party dependencies from source, download:
+
+ * libpng from http://www.libpng.org/pub/png/libpng.html
+ * gettext from http://www.gnu.org/software/gettext/
+ * gsl from http://www.gnu.org/software/gsl/
+
+Extract each library and build them using the following commands:
+
+ env CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk \
+             -arch i386 -arch ppc -mmacosx-version-min=10.4" \
+     LDFLAGS="-arch i386 -arch ppc" \
+ ./configure --prefix=$XAOS_ROOT/src/ui/ui-drv/cocoa/thirdparty \
+             --disable-dependency-tracking
+
+ make
+ make install
+
+Be sure to replace $XAOS_ROOT with the root of your XaoS folder. This 
+will install the libraries and headers in src/ui/ui-drv/cocoa/thirdparty
+where the Xcode project will be able to find them.
+	   
+For more information about building open source libraries as universal 
+binaries see:
+	   
+ http://developer.apple.com/technotes/tn2005/tn2137.html
+	
+
+Building XaoS
+-------------
+
+The Mac OS X version of XaoS is not compiled using the configure scripts in
+the root directory.  Instead, use the Xcode project located in:
+
+ src/ui/ui-drv/cocoa/XaoS.xcodeproj
+
+If the libraries were installed properly, you should be able to build XaoS
+from the Xcode project.

+
+o Removed support for unmaintained platforms (DOS, BeOS, Plan 9, etc.)
+
+o Updated documentation to reflect infrastructure changes
+  (Discussion and issue tracking have moved to Google Groups and Google Code)
+
+o Additional fractal examples by J.B. Langston
+
+
+Windows-specific changes
+========================
+
+o Improved GUI appearance with modern fonts and controls on XP and Vista
+
+o Help format changed from WinHelp to HtmlHelp.  WinHelp was no longer
+  supported starting with Windows Vista and Windows 7.
+
+o Fixed bug where output was invisible when using XaoS from the command line
+
+o Simplified and improved build instructions for Windows developers
+
+
+GTK+ User Interface (Beta)
+==========================
+
+The GTK+ user interface is approaching beta quality.  We welcome beta 
+testers to try out this version and let us know what issues you encounter. 
+Please share your feedback with us on the developer's discussion group at:
+http://groups.google.com/group/xaos-devel.
+
+We ask that beta testers be advanced users who are comfortable compiling
+software from source and submitting useful bug reports including backtraces.
+If you are not comfortable with this, then please wait for the final version
+to be released.  We would also really appreciate it if any experienced GTK+ 
+developers can review our code and make suggestions for improvement. 
+
+Since the GTK+ UI is still not ready for everyday use, it will not be 
+compiled by default. You must explicitly enable it using the following
+configure switch:
+
+	--with-gtk-driver=yes
+
+In addition, we recommend you disable all other drivers when using the GTK
+driver using the following configure switches:
+
+	--with-x11-driver=no
+
+
+New Documentation Format (Beta)
+===============================
+
+We are in the process of migrating the XaoS help system to Sphinx and
+reStructuredText.  Our  user manual was previously in a crippled subset 
+of HTML that we dubbed XSHL, which was missing many features necessary 
+for maintaining modern, attractive documentation.  
+
+Sphinx was developed by the Python project for their documentation, and 
+it is very similar to a Wiki in the way you mark  up the text.  It can 
+output the results as HTML, PDF, and Windows Help.  It supports all the
+important things that are missing from the current help format, such as
+tables, images, and internet hyperlinks.  It can even convert LaTeX math 
+markup into image files that get included in the HTML output.
+
+The documentation still needs a lot of work before it is ready, and we 
+have to make some modifications to Sphinx itself in order to integrate 
+the documentation it produces with XaoS's help system.  However, it is 
+far enough along that we would welcome volunteers who are familar with 
+reStructuredText to submit improvements to the documentation.
+
+The new documentation is located in the help/rest directory, and it can
+be converted into HTML or PDF using the included Makefile.  In order to
+generate the output, you will need to install Sphinx.  Visit the Sphinx
+homepage at http://sphinx.pocoo.org/ for installation instructions and
+more information on the new documentation format.
+
+If you would like to help with the documentation, please contact us on 
+the discussion group at: http://groups.google.com/group/xaos-devel.
+We will be happy to help you get started.

+
+RELEASE NOTES FOR XAOS VERSION 3.4
+----------------------------------
+
+Cross-platform changes
+======================
+
+o New Italian translation courtesy of Sergio Zanchetta
+
+o Updated catalog and i18n for German by Andreas Madritsch
+
+o Bug fix to prevent garbled characters when using non-English languages
+  on modern systems using UTF-8
+
+o Bug fix to prevent XaoS from crashing after using the Render Animation
+  functionality
+
+o Bug fix to prevent incorrect colors on smooth coloring modes with
+  certain video modes
+
+Mac-specific changes
+====================
+
+This is a huge release for Mac users. The Mac user interface has been
+completely rewritten in Cocoa and improved in a number of ways:
+
+o Standard Aqua dialog boxes instead of the strange-looking Unixy things
+  in previous versions. Fields in dialog boxes now support cut and paste
+  as you would expect.
+
+o Pop-up menus are now displayed using standard Aqua menus
+
+o Menu bar in full-screen mode is now the standard Mac OS X menu bar. It
+  automatically slides into view when you move your mouse to the top of
+  the screen and slides out when you move away from it.
+
+o XaoS now has a standard Aqua about dialog box, which displays links to
+  license and credits in help file.
+
+o Help is now displayed via Mac OS X's standard help viewer. Tutorials
+  can still be launched via links in  the help viewer.
+
+o Support for opening xpf (Saved Position) and xaf (Saved Animation)
+  files directly from Finder via drag and drop and by double-clicking.
+  XaoS now includes its own document icon for these files as well.
+
+o Support for basic AppleScriptability via the standard script
+  dictionary. Includes things like opening files and manipulating the
+  window, but no XaoS-specific functionality.
+
+o Support for panning the fractal with the mouse scroll wheel or
+  trackpad two-finger gestures.
+
+In addition to the user interface improvements, XaoS for Mac has the
+following improvements:
+
+o Now uses greater precision (long double) for calculations to enable
+  much deeper zooms.
+
+o In addition to English, XaoS for Mac OS X now supports the following
+  languages: Czech, French, German, Hungarian, Italian, Romanian, and
+  Spanish.
+
+o Integration with Stone Design's Videator (http://stone.com/Videator/).
+  XaoS can now send live a live video stream to Videator, which can then
+  do post-processing using Mac OS X's core video technology. This is
+  great for VJing (live video performance art). See
+  http://stone.com/Videator/VJ.html for more details.
+
+o Edge Detection and Pseudo 3D filters now work correctly.  Fixed a
+  bug that previously caused them to render the image completely black.
+
+Experimental GTK+ Port
+======================
+
+An experimental GTK+ user interface has been added in the src/ui/ui-drv/gtk
+directory. Eventually we hope to replace the old X11 interface with this
+one so that XaoS will blend in seamlessly with the GNOME environment.
+
+Right now, this port is incomplete and it should be considered an alpha-
+quality preview. As such, the GTK+ port will not be compiled by default.
+You must explicitly enable it using the following configure switch:
+
+	--with-gtk-driver=yes
+
+In addition, we recommend you disable all other drivers when using the GTK
+driver using the following configure switches:
+
+	--with-x11-driver=no
+	--with-dga-driver=no
+	--with-ggi-driver=no
+	--with-aa-driver=no
+
+Please do not report bugs against the GTK+ driver. We know that it is very
+buggy and we are working to rapidly improve it. If you want to help with the
+GTK+ driver's development, please contact the xaos-devel mailing list first,
+since it is likely that your patches could conflict with the rapid development
+that is taking place on this driver.
+
+RELEASE NOTES FOR XAOS VERSION 3.3
+----------------------------------
+
+This release is mostly done by Mateusz Malczak who implemented user
+formula support for XaoS. This feature has been a huge demand for
+several years and we proudly (humbly?) announce it to the public
+audience now.
+
+Mateusz has been working on the underlying SFFE (SegFault Formula
+Evaluator) library for several months. XaoS-3.3 can be compiled using
+both NASM (Netwide Assembler) or GSL (GNU Scientific Library) for the
+underlying complex arithmetics used by SFFE. For more information about
+the available user functions please read the enclosed documentation 
+(see online help, "Other things to read", last entry), or visit
+Mateusz's info page on http://www.segfaultlabs.com/sfXaoS.
+
+User formula support has been tested on Linux, Windows, and Mac OS X 
+systems. Recent Ubuntu versions should work without any problems.
+
+You may also notice that internationalization can be broken on modern
+Linux systems. This is due to the use of Unicode (UTF8) by default on
+these operating systems (including Ubuntu 7.x). To solve these
+problems please read Section 6 in src/i18n/README. If you are a packager
+of a Linux distribution, you may consider to add extra codepages for
+standard locales to the dependency list of XaoS (or create a package
+which installs an extra locale if needed).
+
+In addition, this version includes several fixes to the X11 driver 
+contributed by Tormod Volden. These improve compatibility with recent 
+versions of Xorg (-fullscreen and -root options), XScreenSaver 
+(-window-id), and Beryl and Compiz (extreme transparency).
+
+Other improvements include a bug fix for color cycling and a performance 
+mode, which inhibits text output when using XaoS for public exhibition 
+(VJing). These changes were contributed by Andrew Stone.
+
+Finally, this version includes several build improvements for Mac OS X
+and a bug fix for incorrect colors on Intel Macs when switching from
+fullscreen to windowed mode.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.2.3
+------------------------------------
+
+Romanian translation added. Contributed by Ilinca Sitaru.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.2.2
+------------------------------------
+
+This release contains a rewritten Mac OS X port by J. B. Langston III,
+and some small fixes for pipes by Marton Torok. For more details
+please read the ChangeLog file.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.2.1
+------------------------------------
+
+A new fractal type, the Spidron hornflake has appeared. We changed
+the web site to a dokuwiki database, so the help system contains
+now a converter for dokuwiki (not completely working yet).
+
+STICKY/DESTDIR is now supported (by Claudio Fontana). The French
+translation is updated (by Philippe Wautelet). Bigger fonts are
+available for Latin-2 based usage if the user changes the screen
+resolution more than 800x600 or 1000x720.
+
+Some small fixes have been done in the catalog files.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.2
+----------------------------------
+
+Main points are the classic Sierpinski and Koch fractals, but still
+other formulas are introduced. Some 'oldie but goldie' fractals are
+included from the Fractint formula database. The keystroke order has been
+changed a little bit. Now gcc-4.0.x is also supported (-mcpu is deprecated
+now and the source had to be modified for this).
+
+The new formulas are demonstrated with 3 new tutorial movies. These are
+also available in Hungarian language. Volunteers are requested to
+translate the new movies into other languages.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.1.3
+------------------------------------
+
+Using this release gcc version 4.0 should also compile the code, not only
+the 3.x versions.
+
+Two new fractal types were also added. In addition, the DirectX header
+files have been fixed. The French translations are updated.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.1.2
+------------------------------------
+
+This release is a fast bugfix for some gcc versions (or more precisely,
+there is a workaround for the B-B bug, see the ChangeLog for details).
+The example files were not able to load in version 3.1.1 and msgmerge
+was not recognized (this is fixed, however not tested yet).
+
+There are other small but irrelevant fixes (see ChangeLog), too.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.1.1
+------------------------------------
+
+This release is a CVS snapshot freeze for those who are using newer
+systems. The most important update is a fix for gcc-3.4. There are also
+
+- improvements in French and Spanish translations,
+- some more example files (contributed by Zsigmond Kovács),
+- some fixes which patch annoying problems.
+
+For other issues please read the ChangeLog file.
+
+
+RELEASE NOTES FOR XAOS VERSION 3.1
+----------------------------------
+
+We would like to release a quality product in all manner. Unfortunately,
+such a complex software like XaoS requires many details and it does not
+seem to be so easy to put a quality software together.
+
+Well, we did all our best... Here come the latest release binaries
+for Linux, Windows and DOS. They should work with the following
+restrictions:
+
+1. The Linux version seems to be the most stable one. Almost
+   no bugs were encountered testing it the last few weeks.
+   SuSE 7.3 and SuSE 8.0 should be good enough to compile
+   it. The latest source has been also tested on the Compile
+   Farm of SourceForge.net with the next results:
+   
+   * [x86] Linux 2.4 (Debian 2.2)
+     Compiles OK. Seems to be build properly.
+     
+   * [x86] Linux 2.4 (Red Hat 7.3)
+     Compiles OK, runs properly. It is suggested to
+     configure it with --with-mitshm=no to avoid immediate
+     exit after startup. Runs correctly in an X11 window
+     on cf.sf.net.
+     
+   * [x86] FreeBSD (4.7-STABLE)
+     ./configure exits properly, make stops with an error.
+     
+   * [Alpha] Linux 2.2 (Debian 3.0)
+     ./configure exits properly, make stops with an error
+     during compiling ui.c.
+     
+   * [PPC - G4] MacOS X 10.1 SERVER Edition
+     Compiles OK, the executable gave MIT/SHM problem
+     with "./configure". It should work with --with-mithsm=no,
+     but currently I have no access to any Mac OS X
+     systems to test this.
+     
+   * [Sparc - Ultra60] Linux 2.4 (Debian 3.0)
+     Compiles OK, seems to be build properly.
+     
+   * [Sparc - R220] Sun Solaris (8)
+     ./configure stops with an error.
+     
+   * [CerfCube SA 1110] Linux 2.4 (Debian 3.0)
+     Compiles OK, seems to be build properly.
+     
+   * [J2EE] IBM WebSphere
+     Compiles OK, runs properly.
+     
+   I tried to run the executables, mostly I got "Cannot initialize
+   driver", except where I wrote "runs propery" above. I'm almost sure
+   that those platforms I wrote "seems to be build properly" for, XaoS
+   will work without any problems, because there should be only "Can't
+   open display"-related configuration errors on cf.sf.net and/or at my
+   place.
+   
+   You can also realize that internationalization (i18n) will only work
+   if you install XaoS as the system administrator with "make install".
+   Future releases may solve this problem.
+   
+   Tcl/Tk interface now works, but it is not updated since a rather long
+   time. You can run it entering "wish ./xaosmenu.tcl &" in a Unix shell
+   in the bin/ directory. This interface is experimental.
+   
+   Under SVGAlib latin2 fonts will not work for some internationalized
+   messages.
+   
+   For compilation with Aalib, you need version 1.4 which can be
+   downloaded from http://aa-project.sf.net.
+   
+2. Microsoft DOS users will enjoy i18n if their system supports it.
+   Unfortunately some systems have to have plain DOS to make i18n
+   available. Many Windows systems also support running batch
+   files from native Windows, however not all (my Windows NT 4
+   does not). DOS users should run xaos-??.bat in the bin\
+   directory.
+   
+   Note that some messages in latin2 fonts will not be displayed
+   correctly.
+   
+   Aalib may not work 100% correctly. It may depend on your DPMI
+   settings. You should download the latest csdpmi*.zip package.   
+   
+   If you want to compile XaoS from scratch, you should download
+   the following software:
+   
+   aalib-1.4rc5.tar.gz, all402.zip, bnu213b.zip, djdev203.zip,
+   fil41b.zip, gcc2952b.zip, gtxt040b.zip, licv17b.zip, mak3791.zip,
+   png1012b.zip, txi42b.zip, zlib114b.zip.
+   
+   Aalib must be patched to compile it (I sent a patch to the
+   SourceForge Tracker) and libvga and libtext (needed for Aalib) must
+   be also installed. Note that libtext will not compile under the
+   newest DJGPP, if someone know why DJGPP fails to compile the
+   appropriate assembly code, please write to us.
+   
+3. XaoS has i18n support under Microsoft Windows now. You are not
+   suggested changing the drivers many times because XaoS will
+   crash.
+   
+4. Here is a list about recent bugs and problems:
+     
+   * Fixing Macintosh version (load/save works incorrectly).
+   * Checking why Bailout item is duplicated in Windows help.
+   * Displaying latin2 fonts correctly.
+   * Fixing catalog files (mainly French and Spanish).
+   * Filling up i18n for menu files for some languages.
+   * Fixing Macintosh version (crash when loading random examples).
+   * Fixing Windows version (crash when several times saving files
+     and configurations).
+   * Fixing generated xaos.dlg for certain languages (e.g. Hungarian).
+   * Fixing crashing configure/make for all problematic platforms.
+   * Rewriting i18n to be easier to add new menus and others.
+   * All other todos announced in TODO file.
+
+That's all. However the problem list is quite long, we hope
+you will enjoy XaoS 3.1.

+
+Jan Hubicka is the main author of XaoS. He wrote the biggest parts of
+this program, in fact, all the most important things.
+
+Andreas Madritsch helped a lot putting together version 3.1. He also
+compiled the DOS and Windows executable and made German translations of
+menu items available. He added bailout and 3 fractal types into version
+3.1. He also fixed i18n to work under Windows correctly.
+
+Zoltan Kovacs wrote this documentation about the recent installation
+problems and he was finalizing release 3.1. He added i18n support into
+XaoS and cleaned up the code as it was possible.
+

+XaoS - a real time fractal zoomer and morpher
+=============================================
+
+For installation instructions please see the INSTALL file.
+
+Original authors of XaoS are Jan Hubicka (jh@ucw.cz) and Thomas  Marsh
+(tmarsh@tivoli.com). Many other people contributed to the project as
+well. Their list is too long to be included here. See AUTHORS file in
+the XaoS distribution.
+
+
+INTRODUCTION
+------------
+
+XaoS is a fast portable real-time interactive fractal zoomer. It
+displays the Mandelbrot set (among other escape time fractals) and
+allows you to zoom smoothly into the fractal. Various coloring modes are
+provided for both the points inside and outside the selected set. In
+addition, switching between Julia and Mandelbrot fractal types and
+displaying planes is provided. The first version was a poorly written
+Mandelbrot viewer by Thomas later modified by Jan to support high
+frame-rate zooming. Other additions were later made including autopilot 
+(for those of you without driver licenses), palette changing, PNG
+saving, and fractal inversion.
+
+
+SUPPORTED PLATFORMS
+-------------------
+
+Starting from version 3.5, the supported platforms are:
+
+  * POSIX (Linux, FreeBSD, Solaris, etc.)

+  
+The following platforms were also supported in earlier versions:
+
+  * BeOS
+  * Old Macintosh versions
+  * Microsoft DOS
+  * OS/2
+  * Plan 9
+
+Due to the lack of volunteers interested in maintaing older platforms, we 
+are discontinuing support for them.  If you want to use XaoS on one of
+these platforms, please download an earlier version.
+
+Of course, volunteers are always welcome to resurrect support for older
+platforms or port XaoS to other platforms it doesn't currently support.

+----------
+
+Visit the issue tracker at http://code.google.com/p/gnuxaos/issues/list
+for a list of outstanding issues.
+
+In particular, we would welcome volunteers to help us finish the 
+following projects that we are currently focusing on:
+
+
+GTK+ User Interface (Beta)
+==========================
+
+The GTK+ user interface is approaching beta quality.  We welcome beta 
+testers to try out this version and let us know what issues you encounter.

+
+
+New Documentation Format (Beta)
+===============================
+
+We are in the process of migrating the XaoS help system to Sphinx and
+reStructuredText.  Our  user manual was previously in a crippled subset 
+of HTML that we dubbed XSHL, which was missing many features necessary 
+for maintaining modern, attractive documentation.

+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl    default (if it is not specified or empty) is 'no-libtool'.
+dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl    depending on --{enable,disable}-{shared,static} and on the presence of
+dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl    $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl    implementations (in libc or libintl) without the ngettext() function
+dnl    will be ignored.  If NEEDSYMBOL is specified and is
+dnl    'need-formatstring-macros', then GNU gettext implementations that don't
+dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries.  If empty,
+dnl    the value `$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl    and used.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl    Catalog format: GNU --> install in $(datadir)
+dnl    Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl    Catalog format: none
+dnl    Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+#If it is a problem in your langage catalog, let me
+#know and I will create a special key
+def2 "Was heisst das?"
+def3 "Um dies zu erklären, müssen wir zuerst
+verstehen, was die topologische- und
+die Hausdorff-Besicovich-Dimension
+sind."
+
+topo1 "Die topologische Dimension
+ist die \"normale\" Dimension."
+topo2 "Ein Punkt hat 0 Dimensionen"
+topo3 "Eine Linie hat 1 Dimension"
+topo4 "Eine Fläche hat 2, usw."
+
+hb1 "Die Definition der
+Hausdorff-Besicovich-Dimension
+kommt von der einfachen Tatsache, dass"
+hb2 "eine Linie die so gezoomt wird,
+dass sich ihre Länge verdoppelt,
+danach zwei mal so lang ist,
+wie sie vorher war."
+hb3 "Andererseits wächst die Ausdehnung
+eines Quadrates, das in gleicher Weise
+gezoomt wird, um den Faktor vier."
+hb4 "Ähnliche Regeln funktionieren auch
+für Objekte, die sich in mehrere
+Dimensionen ausdehnen."
+hb5 "Um Dimensionen mit Hilfe dieser
+Tatsache zu berechnen, kann folgende
+Gleichung benutzt werden:"
+hb6 "Dimension = log s / log z,
+wobei z dem Zoomfaktor
+und s der Ausdehnung entspricht"
+hb7 "Wird eine Linie um den Faktor 2
+gezoomt, ändert auch die Ausdehnung
+um den Faktor 2.
+log 2 / log 2 = 1"
+hb8 "Wird ein Quadrat um den Faktor 2
+gezoomt, ändert die Ausdehnung um den
+Faktor 4.
+log 4 / log 2 = 2"
+hb9 "Diese Definition führt zu den
+erwarteten Resultaten für normale
+Formen."
+hb10 "Interessanter wird es bei Fraktalen."
+hb11 "Sehen Sie sich die so genannte kochsche
+Schneeflockenkurve an,"
+hb12 "welche entsteht, wenn man eine Linie in
+drei gleiche Abschnitte teilt und den
+Mittleren durch zwei ebenso lange
+Abschnitte ersetzt und diesen Vorgang
+beliebig oft wiederholt."
+hb13 "Die neuen Linien haben 1/3 der Grösse
+der ursprünglichen Linie."
+hb14 "Nach dem Zoomen um den Faktor 3,
+sind diese Linien exakt gleich lang
+wie die ursprüngliche Linie."
+hb15 "Wegen der Selbstähnlichkeit, die durch
+unendlich wiederholtes Teilen entsteht,"
+hb15b "wird jedes dieser Teile eine exakte
+Kopie des ursprünglichen Fraktals."
+hb16 "Weil beim Teilen vier solche Kopien
+entstehen, wächst die Ausdehnung des
+Fraktals um den Faktor 4."
+hb17 "Nun setzen wir diesen Wert in unsere
+Gleichung ein:
+log 4 / log 3 = 1.261"
+hb18 "Wir erhalten einen Wert der grösser als
+1 (die topologische Dimension der
+Kurve) ist."
+hb19 "Die Hausdorff-Besicovich-Dimension
+(1.261) ist grösser als die
+topologische Dimension."
+hb20 "Gemäss dieser Definition 
+ist die Schneeflockenkurve ein Fraktal."
+
+defe1 "Diese Definition ist jedoch nicht
+perfekt, da sie eine Menge Formen
+ausschliesst, die auch Fraktale sind."

+#Definition from the intro.xaf is displayed here.
+#If it is a problem in your langage catalog, let me
+#know and I will create a special key
+def2 "What does this mean?"
+def3 "To explain it we first need
+to understand what the topological and
+Hausdorff Besicovich dimensions are."
+
+topo1 "The topological dimension
+is the \"normal\" dimension."
+topo2 "A point has 0 dimensions"
+topo3 "A line has 1"
+topo4 "A surface has 2, etc..."
+
+hb1 "The definition of the
+Hausdorff Besicovich dimension
+comes from the simple fact that:"
+hb2 "A line that is zoomed so that it doubles
+in length is twice as long as it was."
+hb3 "On the other hand, the size
+of a square that is similarly zoomed
+grows by four times."
+hb4 "Similar rules work in higher
+dimensions too."
+hb5 "To calculate dimensions from
+this fact, you can use the
+following equation:"
+hb6 "dimension = log s / log z
+where z is the zoom change and
+s is the size change"
+hb7 "for a line with zoom 2,
+the size change is also 2.
+log 2 / log 2 = 1"
+hb8 "for a square with zoom 2,
+the size change is 4.
+log 4 / log 2 = 2"
+hb9 "So this definition gives
+the same results for normal shapes"
+hb10 "Things will become more interesting
+with fractals..."
+
+hb11 "Consider a snowflake curve"
+hb12 "which is created by repeatedly
+splitting a line into four lines."
+hb13 "The new lines are 1/3 the size of
+the original line"
+hb14 "After zooming 3 times, these lines will
+become exactly as big as the
+original lines."
+hb15 "Because of the self similarity created
+by the infinite repeating
+of this metamorphosis,"
+hb15b "each of these parts will
+become an exact copy of the original
+fractal."
+hb16 "Because there are four such copies, the
+fractal size grows by 4X"
+hb17 "After putting these values in equations:
+log 4 / log 3 = 1.261"
+hb18 "We get a value greater than 1
+(The topological dimension
+of the curve)"
+hb19 "The Hausdorff Besicovich dimension
+(1.261) is greater than the
+topological dimension."
+hb20 "According to this definition, 
+the snowflake is a fractal."
+
+defe1 "This definition, however, is not
+perfect since it excludes lots of
+shapes which are fractals."

+escape1 "Some fractals (like snowflake)
+are created by simple subdivision
+and repetition."
+escape2 "XaoS can generate a different
+category of fractals - called
+escape time fractals."
+escape3 "The method to generate them
+is somewhat different, but is also
+based on using iteration."
+escape4 "They treat the whole screen as
+a complex plane"
+escape5 "The real axis is placed horizontally"
+escape6 "and the imaginary is placed vertically"
+escape7 "Each point has its own orbit"
+escape8 "The trajectory of which is calculated
+using the iterative function, f(z,c)
+where z is the previous position and c
+is the new position on the screen."
+escape9 "For example in the Mandelbrot
+set, the iterative function is z=z^c+c"
+orbit1 "In case we want to examine
+point 0 - 0.6i"
+orbit2 "We assign this parameter to c"
+orbit3 "Iteration of the orbit
+starts at z=0+0i"
+orbit3b "Then we repeatedly calculate
+the iterative function, and we
+repeatedly get a new z value for
+the next iteration."
+orbit4 "We define the point that belongs to the
+set, in case the orbit stays finite."
+orbit5 "In this case it does..."
+orbit6 "So this point is inside the set."
+orbit7 "In other cases it would
+go quickly to infinity."
+orbit8 "(for example, the value 10+0i
+The first iteration is 110, 
+the second 12110 etc..)"
+orbit9 "So such points are outside the set."
+
+bail1 "We are still speaking about
+infinite numbers and iterations
+of infinite numbers..."
+bail2 "But computers are
+finite, so they can't
+calculate fractals exactly."
+bail3 "It can be proved that in the
+case where the orbit's distance from
+zero is more than 2, the orbit
+always goes to inifinity."
+bail4 "So we can interrupt calculations
+after the orbit fails this test.
+(This is called the bailout test)"
+bail5 "In cases where we calculate points
+outside the set, we now need just a
+finite number of iterations."
+bail6 "This also creates the colorful
+stripes around the set."
+bail7 "They are colored according to the
+number of iterations of orbits needed
+to fall in the bailout set."
+iter1 "Inside the set we still
+need infinite numbers of calculations"
+iter2 "The only way to do it is to interrupt
+the calculations after a given
+number of iterations and
+use the approximate results"
+iter3 "The maximal number of iterations
+therefore specifies how exact 
+the approximation will be."
+iter4 "Without any iterations you would create
+just a circle with a radius of 2
+(because of the bailout condition)"
+iter5 "Greater numbers of iterations makes
+more exact approximations, but
+it takes much longer to calculate."
+limit1 "XaoS, by default, calculates
+170 iterations."
+limit2 "In some areas you could zoom for a
+long time without reaching this limit."
+limit3 "In other areas you get

+hb3 "Por otro lado, el tamaño de un

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.
+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases

+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.

+\`configure' configures XaoS 3.5 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+Title:          XaoS - a fast portable real-time interactive fractal zoomer/morpher
+Version:        3.4
+Entered-date:   Sep 28 2008
+
+Description:    XaoS is a fast portable real-time interactive fractal zoomer.
+		It displays the Mandelbrot set (among other escape
+		time fractals) and allows you to zoom smoothly into the fractal.
+		Various coloring modes are provided for both the points inside 
+		and outside the selected set. In addition, switching between 
+		Julia and Mandelbrot fractal types is provided. The first 
+		version was a poorly written Mandelbrot viewer by Thomas later 
+		modified by Jan to support high frame-rate zooming. Other 
+		additions were later made including autopilot (for those of 
+		you without driver licenses), palette changing, PNG saving, 
+		and fractal inversion.
+Keywords:       X11 fractal realtime zoom mandelbrot newton
+		julia autopilot demo

+NAME
+====
+
+texi2rest - Convert texinfo xml represenation to reStructuredText
+
+SYNOPSIS
+========
+
+texi2rest *xmlfile* > *restfile*
+
+DESCRIPTION
+===========
+
+``texi2rest`` is based on ``xhtml2rest`` by Antonios Christofides. He
+included the following disclaimer for his program, and it applies
+equally to mine: far from being a decent and complete program, this is
+only something to begin with, which hopefully processes the given UTF-8
+texinfo xml file and produces reStructuredText "source code" in the
+standard output.
+
+Before processing the texinfo file, you must convert it to xml using
+the makeinfo command:
+
+    makeinfo --xml *texifile*
+
+    texi2rest *xmlfile* > *restfile*
+
+LIMITATIONS
+===========
+
+I am writing this specifically to convert the XaoS project's
+documentation. I do not plan to implement full conversion of every 
+texinfo directive--only the ones used in the documentation I am trying
+to convert. Hopefully other interested parties will contribute further
+improvements.
+
+
+META
+====
+
+``texi2rest`` was hacked together by J.B. Langston, 
+jb-langston@austin.rr.com, based on ``xhtml2rest`` by
+Antonios Christofides, anthony@itia.ntua.gr.

+@section Why yet another fractal generator?
+
+
+We decided to make XaoS, because all fractal browsers we know of take a
+long time to calculate each image. You may browse nice images
+generated by them but real impressions of fractals --- the self
+similarity and infinite zooming into the nice parts of fractals ---
+can be seen only in animations. There are many programs available that
+make nice animations, but they take a long time to calculate and lots
+of space on disk. Most such animations are quite ugly because their
+authors can't see them without many hours of calculations.
+
+A natural question is: is it possible to generate such animations in
+real-time? The answer was negative for many years, since the Mandelbrot set is
+very computationally expensive. Things are changing. Today's computers
+are fast enough to calculate approx. 10.000 of pixels per frame,
+which is enough 
+for a very low resolution animation (100x100). Several programs doing that
+are available. But 100x100 animation still looks quite ugly. To make
+animation nice you need at least 320x200 pixels. And that is 6 times more!
+One possibility is to wait until computers will be fast enough, but
+it will take many years, and then 320x200 animations will be obsolete
+and everyone will want 1024x768 resolution instead or more.
+
+We found a special algorithm that saves up to 99.98% of calculations during
+zooming by reusing pixels already calculated in previous frames. There were
+some programs doing similiar tricks before but we don't know about any able
+to do zooming interactively with a speed similar to XaoS. Many other tricks
+were later implemented XaoS to achieve yet higher framerates. Now XaoS does
+up to 120 frames per second on a 120Mhz pentium in a fullscreen 320x200
+animation, and calculates an average of 160 (0.24%) pixels per frame. This makes
+XaoS fast enough to achieve its primary goal, realtime animation, but there
+are still many areas that could improve, since more complex fractals,
+higher resolutions, or slower computers still bring many problems.

+1.1 Why yet another fractal generator?
+======================================
+
+We decided to make XaoS, because all fractal browsers we know of take a
+long time to calculate each image. You may browse nice images generated
+by them but real impressions of fractals -- the self similarity and
+infinite zooming into the nice parts of fractals -- can be seen only in

+
+1.2 What does this software do then?
+====================================
+
+XaoS is a realtime interactive fractal zoomer. This means that it lets
+you zoom smoothly into any place in the fractal you choose without the
+many hours of calculation required by most other fractal generators. It
+now has many other features too, like 13 different fractal types,
+autopilot, special coloring modes, support for various bit depths
+(8bpp, truecolor, hicolor and realcolor), random palette generation,
+color cycling etc...
+
+
+File: xaos.info,  Node: tutorial,  Next: controls,  Prev: Overview,  Up: Top
+
+2 XaoS tutorial
+***************
+
+This is a brief introduction to the basic XaoS features.
+
+2.1 How to zoom
+===============
+
+The main advantage of XaoS is that after a few seconds' delay to
+calculate the first image, you may choose any point with the mouse and
+press the _left_ button.  The image will start to zoom smoothly into
+the point you choose. You may move the mouse and zoom smoothly into
+interesting areas. By pressing the _middle button_ (or _left+right_
+buttons) you may also _move the image_ using "drag & drop" if you
+missed an interesting place. _Unzooming_ is also possible by using the
+_right button_, but it is much slower because optimizations are not so
+effective as for zooming.
+
+   In case you think that the default _speed_ is boring (it is quite
+slow, to make XaoS smooth on a slow computer) you may change it by
+pressing _arrow up/down_. But faster zooming is more expensive, so if
+the speed is too high you will see little but funny colorful blinking
+rectangles.
+
+2.2 Autopilot
+=============
+
+To make XaoS yet more impressive we made a special autopilot that
+automatically drives into interesting boundaries of the set. So you can
+press `A', play your favorite music, drink coffee and relax. I never
+tried this but it should be really relaxing! Many pictures in the XaoS
+gallery were discovered using the autopilot.
+
+   The autopilot also has some additional features. It turns back when
+the zoomed picture stops being interesting, and is able to spot when
+it's zoomed into a really boring part (or has reached the limit of
+floating point numbers) and restart zooming from the top.
+
+2.3 Various fractal formulae
+============================
+
+XaoS also supports formulae other than the Mandelbrot set. You may
+change _formula_ using the _number keys_ or _SHIFT+letters_.
+
+   On keys `1' to `5' are _Mandelbrot sets of various power_. The
+"normal" Mandelbrot set is on key `1'.
+
+   On key `6' is a fractal called _Newton_. It is Newton's famous
+formula for finding roots.
+
+   On key `7' is the _fourth ordered Newton_ fractal.
+
+   On key `8' is a fractal called _Barnsley_.
+
+   On key `9' is _Barnsley's second_ fractal.
+
+   On key `0' is _Barnsley's third_ fractal.
+
+   With keys `SHIFT-A' you can display a fractal called _octo_. It is a
+fractal that Thomas discovered in fractint.
+
+   With keys `SHIFT-B' you can display a fractal called _Phoenix_. It
+is a very nice and quite famous fractal.
+
+   With keys `SHIFT-C' you can display a fractal called _Magnet_. This
+fractal has quite a complex formula so it is a bit slow.
+
+   With keys `SHIFT-D' you can display the _Magnet2_ fractal.
+
+   The rest of the built-in fractals are accessible through an other
+menu, but you can still use the hotkeys.
+
+   On `SHIFT-E' is a fractal called _Triceratops_ found by Arpad.
+
+   On `SHIFT-F' is a fractal called _Catseye_ found by Arpad.  This is
+more interesting if you change the bailout value.
+
+   On `SHIFT-G' is a fractal called _Mandelbar_. It was in Gnofract4d,
+and they found it at: http://mathworld.wolfram.com/MandelbarSet.html
+
+   On `SHIFT-H' is the _Lambda_ fractal.
+
+   On `SHIFT-I' and `SHIFT-J' are the _Manowar_ and _Spider_ fractals,
+they were found by users of fractint.  (Scott Taylor or Lee Skinner) It
+was on http://spanky.triumf.ca/www/fractint/ taylor_skinner_type.html
+
+   The next 3 fractals are famous classic fractals.
+
+   On `SHIFT-K' is the _Sierpinski_ Gasket.  You can change its shape
+by selecting another Julia seed.  (This is for technical reasons.)
+
+   On `SHIFT-L' is the _Sierpinski Carpet._ It's shape can also be
+changed by selecting another Julia seed.
+
+   On `SHIFT-M' is the _Koch Snowflake._
+
+2.4 Out-coloring modes
+======================
+
+To make fractals yet more interesting, more coloring modes for points
+outside the set are provided. "Classical coloring mode" uses the number
+of iterations that the orbit required to escape to (nearly) infinity.
+You can change this mode from the _Fractal menu_ or by pressing key `C'
+To see more about coloring modes, try the tutorial on Incoloring modes
+from the XaoS features overview.
+
+   Those cryptic names for coloring modes are mathematical formulae,
+where _iter_ means number of iterations, _real_ means real coordinate
+of last orbit, and _imag_ means imaginary coordinate of last orbit.
+
+2.5 In-coloring mode
+====================
+
+In-coloring mode is similar to out-coloring, except that it changes how
+things inside the set are displayed. This can also be changed from the
+_fractal menu_ or by pressing `F'.
+
+   You might also want to see the tutorial on Out-coloring modes from
+the XaoS features overview.
+
+2.6 Planes
+==========
+
+All fractals displayed by XaoS are functions with a complex parameter.
+It can be displayed in the normal complex plane, where x is the real
+part of the number, and y is the imaginary part; but it can also be
+displayed in a number of other planes. You can select the plane to use
+from the _Fractal menu_, or by pressing `I'.
+
+   Like the coloring modes, planes have cryptic names. You guessed it,
+they're mathematical formulae. Here `mu' means coordinates in the normal
+complex plane. If you have coordinates in `1/mu' plane, and you need
+coordinates in the a complex plane (to calculate the Mandelbrot set) you
+simply use the coordinates as mu. Lambda is another plane that can be
+converted to mu using a similar formula.
+
+*mu*
+     normal mode.
+
+*1/mu*
+     Inversion: infinity goes to 0 and 0 goes to infinity.
+
+*1/(mu+0.25)*
+     Similar to inversion, but moves the center outside of the
+     Mandelbrot set so that it looks parabolic.
+
+*lambda*
+     Lambda plane.
+
+*1/lambda*
+     Inversion of lambda plane.
+
+*1/lambda-1*
+     Inversion with moved center.
+
+*1/(mu-1.40115)*
+     A very interesting mode for the Mandelbrot set. It makes small
+     things big, so you can browse the set's details easily.
+
+2.7 Mandelbrot/Julia switching
+==============================
+
+Most of the fractals displayed by XaoS (currently all of them) have two
+forms: Mandelbrot and Julia. Every point in a Mandelbrot set has its
+own Julia set. To see more about this correspondence, try the tutorial
+on Julia set from the Introduction to fractals.
+
+   In the Mandelbrot mode, you can get a corresponding Julia by moving
+the mouse to an interesting point and pressing `M'. To get back press
+`M' again. Some fractals (Barnsley and phoenix) are already in their
+Julia versions, because the Mandelbrot ones are boring. But by pressing
+`M' in such fractal you should get the Mandelbrot version, and by
+choosing another point as the base point and pressing `M' again you
+should get a completely different fractal. The most interesting points
+for Julia sets are at the boundaries of the Mandelbrot set. Most of the
+Julias inside or outside the set are boring.
+
+2.8 Fast Julia preview mode
+===========================
+
+Fast Julia mode is a quick way to find a point to use as a base for the
+Julia set.. Just press `J' and a small Julia set will be displayed in
+the top left corner. Then move the mouse around with button 1
+depressed, and the Julia for the point the mouse is over will be
+automatically generated.
+
+2.9 Palette
+===========
+
+If you think that the default XaoS colors are ugly or you are just
+bored by them you can change it by pressing `P'. XaoS will
+automatically generate random palettes. Many of them look ugly, so
+press `P' again to get another one until you find one you like.
+
+2.10 Filters
+============
+
+Many interesting effects are done by post-calculation filters. *Note
+filter::.  XaoS has filters that do everything from embossing, through
+motion-blurring, right through to turning the fractal into a
+stereogram. To enable them use the `filter menu' or press `E'.
+
+2.11 Palette cycling
+====================
+
+This is a very old trick that makes the Mandelbrot set a little
+flashier. You may enable or disable it using `Y'. In the truecolor
+modes you need to enable the palette emulator filter first. This is done
+via the `E' key, or from the filter menu.
+
+2.12 Changing number of iterations
+==================================
+
+To calculate fractals perfectly, you need an infinite number of
+iterations. XaoS does just the first few of them, so after lots of
+zooming you may get into a place that looks quite boring, and the
+boundaries of the set are rounded, without any interesting details.
+This can be changed by changing the number of iterations:
+
+   Press and hold `arrow right' and wait until iterations are high
+enough.  This may slow down calculation much. To reduce number of
+iterations press `arrow left'.
+
+2.13 Changing resolution
+========================
+
+XaoS usually starts in a low resolution (320x200 or thereabouts) to make
+calculations faster. If you have a fast computer or you need to save
+bigger `.gif' images, you may change the resolution. This can be done
+by pressing `=' in the full screen drivers, or simply by resizing the
+XaoS window.
+
+2.14 Changing driver
+====================
+
+XaoS usually has more than one driver available. You may change it on
+the fly in case you want a different one. For example, XaoS started in
+X11 can be switched at runtime to use the AA driver. This can be done
+from the UI menu.
+
+   This action is bit dangerous, because XaoS can crash during
+initialization if there is some problem with initialization; XaoS tries
+to initialize a new driver, and if it fails it attempts to return back
+to the original. Sometimes this is impossible, and all XaoS can do is
+terminate..
+
+2.15 Other features
+===================
+
+XaoS has many other features, but they don't fit into this tutorial.
+Most of them are available from the menu, so you can experiment with
+them. You might also want to see the _animated tutorials_ from the
+_help menu_, to have an idea what XaoS can do.

+
+3 Basic controls
+****************
+
+By default the mouse buttons work in the following way:
+
+*left*
+     zoom in
+
+*right*
+     zoom out
+
+*middle*
+     move fractal in a drag-and-drop fashion
+
+   _Note:_ Since most Macs only have one button mice, these controls
+are emulated on Mac OS X using modifier keys. See the help section on
+Mac OS X for details.
+
+   This behavior can change. If you enable rotation, the first button
+is used for rotating fractals. Also, in fast Julia mode, the first
+button is used to change the seed.
+
+   If you don't have a middle button, press both buttons to enable
+emulation.
+
+   After few minutes of zooming you will probably exceed the precision
+and the fractals will get boring. If you are getting strange big
+rectangles on the screen, you probably reached the numeric limit: there
+is no way to avoid this except un-zoom back and choose a different
+area. It doesn't hurt so much, since you have zoomed approximately 64
+051 194 700 380 384 times, so there are quite a lot of areas to
+explore. Algorithms with unlimited precision exist, but they are still
+too slow for real-time zooming.
+
+   The other possibility is that you have reached the iteration limit.
+The fractal is calculated approximately, and in this case you need to
+increase number of iterations used for approximation (and decrease the
+speed in the process).  This is done from the menu or using the arrow
+keys _Left_ and _Right_.
+
+   An _Up_ and _Down_ keys should be used to change zooming speed. Note
+that higher speed costs more and image will be blocky.
+
+   This behavior can also change. With palette cycling enabled, _Left_
+and _Right_ keys change cycling speed; in continuous rotation they
+change rotation speed.
+
+   All other functions are available from the menu, which (in the
+default configuration) are displayed when you move the mouse to the top
+of the screen/window. It is useful to learn the shortcut keys, which are
+shown in gray next to the menu items they trigger.

+
+4 How to encode video files from XaoS
+*************************************
+
+To create a video, make and `xaf' file first (the easiest way to do
+this is to use the _record_ function in the file menu). Then you need
+to render the animation. XaoS can output sequences of ordinary `PNG'
+images, that can later be used by a video encoder.
+
+4.1 Generating image sequences for video
+========================================
+
+To generate an image sequence, choose _Render Animation_ from the _Misc_
+menu. You can also use the following command on the command line:
+
+     xaos -render [filename] -size 352x240 -antialiasing
+     -renderframerate 24 -basename [basename]
+
+   _File to render_ (`[filename]') is the name of the `xaf' file,
+_Basename_ (`[basename]') is the name used as the base filename for
+rendered images. This should also include the path where you want to
+save the images.  XaoS adds a four digit sequence number and `.png'
+extension to this name automatically.
+
+   You might also want to change the resolution. Make sure that the
+resolution you choose is supported by the video codec you wish to use.
+
+   The framerate can also be altered. Make sure you choose a framerate
+that is supported by the video codec you wish to use.
+
+   _Antialiasing_ (`-antialiasing') is used to produce anti-aliased
+images.  It takes a much longer time and much more memory to calculate
+them, but resulting images are better for video compression and they
+result in a much smaller video file.  (the same is true of _JPEG
+images_)
+
+   On the other hand, the other XaoS rendering option _Always
+Recalculate_ (`-alwaysrecalc') (which disables XaoS's zooming
+optimizations) is _not recommended_. If that's used, the sequence of
+animation then contains quite a lot of extra information, which
+increases size of video file, but because of the codec's lossy
+compression it is hard to see any difference, so it's not worth it.
+
+4.2 Rendered files
+==================
+
+Once you start it, XaoS will generate thousands of frames. They take
+quite a long time to calculate and save, and consume plenty of disk
+space.  (e.g. to render part 1 of the tutorial you need about 60MB and
+half an hour of time).
+
+   All images are named `[basename]framenum.png'. For example
+`intro0001.png' is the first frame of the animation intro. If
+consecutive frames are the same, XaoS doesn't save them, so some frames
+may be missing. If your encoder can't handle that, you will need to
+write a simple script which will fill in the gaps by means of `mv' or
+symbolic linking.
+
+   A list of all filenames is saved into the file `[basename].par',
+where each line is the name of one frame. The names repeat here if
+necessary, so you can use this file to supply filenames to the encoder.
+
+4.3 Encoding videos
+===================
+
+Once XaoS has generated the png files for each frame of the animation,
+you can use a third-party video encoder to convert the sequence of
+images into a video file. We currently recommend the following
+encoders, which support a wide variety of video codecs and file formats:
+*ffmpeg*
+     Available from: `http://ffmpeg.mplayerhq.hu/' Instructions:
+     `http://ffmpeg.mplayerhq.hu/faq.html#SEC12'
+
+*mencoder*
+     Part of mplayer, available from: http://www.mplayerhq.hu/
+     Instructions:
+     `http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html'
+   These are both command line tools. If you prefer a graphical tool,
+you may prefer Quicktime Pro from Apple
+(http://www.apple.com/quicktime/pro/). However, this software costs
+approximately US$30, and the authors of XaoS have no experience with
+it. Although QuickTime may be easier to use, the two free encoders
+above are just as capable once you learn how to use them.
+
+   Note: we used to recommend Berkeley parallel MPEG encoder to encode
+the generated png files into MPEG videos. We have kept the instructions
+mainly for historic purposes.

+
+5 XaoS's file format
+********************
+
+This section describes the format used by XaoS for animations,
+configuration files and saved positions. All these files have a common
+format, designed to be easily readable, to allow manual editing of
+files and easy conversion by other programs.
+
+   I also taken care to make it easily extensible for future versions
+of XaoS so I hope there will not be many incompatibilities between
+various XaoS versions.
+
+   The format is a simple set of commands executed sequentially. XaoS
+does not provide any variables/cycles as usual scripting languages do,
+but future extension to full-blown Scheme should be easy since the
+format uses Scheme-like syntax.  The syntax of every command is:
+
+   `(command_name '_[param1] [param2]_`)'
+
+   where parameters are optional and separated by whitespace (an
+arbitrary number of spaces, tabs and newlines). The parameters can have
+the following types:
+
+*integer*
+     number w/o decimal point (`123')
+
+*float*
+     floating point number in decimal notation with optional exponent
+     (`1.23E2')
+
+*keyword*
+     text started by quote `''. It is used to pass various string
+     constants like formula name (`'mandel') Quote is required for
+     scheme compatibility
+
+*string*
+     Text inside double quotes. The only parameter that should contain
+     whitespace
+
+*boolean*
+     `#t' for true or `#f' for false
+
+   There is a complete description of all XaoS functions (with some
+examples) and an index of functions in the XaoS registry. *Note
+menus::. You may particularly want to read about the animation
+functions. *Note animf::. Also, the following functions are significant:
+
+*load*
+     This function loads and interprets a file. It works similarly to
+     `#include' in C.
+
+*initstate*
+     Available in version 3.0 and above, this function resets XaoS's
+     state to default values. This command should be at the beginning
+     of each animation file, since otherwise some stuff previously
+     enabled by user could cause unexpected effects. State is not reset
+     by default before playing animations since it would make it
+     impossible to write macros. Current versions don't really need
+     macros, but in future versions, when the Scheme programming
+     language will be available, this should be a much more interesting
+     subject.
+
+*usleep*
+     This function waits for a selected amount of time(in usec) before
+     processing the next command. The screen is recalculated and
+     displayed at the beginning of the sleep if necessary. The
+     remaining time is spent by waiting, calculating if necessary, or
+     performing any animation you entered via animation commands.
+
+*wait*
+     Waits until the animation or image rendering is complete. Do not
+     call this function when zoom, or continuous rotation is active
+     otherwise deadlock happens. It is a good idea to call it
+     immediately before text subtitles are displayed, since it looks
+     ugly when they are displayed over a blocky unfinished fractal.
+     Because the degree of blockiness at a given instant is a function
+     of your machine speed, it may look nice for you but ugly for
+     others with slower machines. Also you should call this after an
+     animation is performed, before the switch to another fractal
+     happens; since the switch involves calculation, the screen is
+     stopped for a while and an unfinished fractal there looks ugly.
+     You should also call it, when you want to do something as soon as
+     possible.
+
+   Example:
+
+     ;configure everything for the first frame
+     (inistate)
+     (palette 1 1163254293 0) ;custom palette
+     (cycling #t) ;enable cycling
+     (cyclingspeed 7)
+     (maxiter 276) ;higher number of iterations
+     (range 3) ;default range for solid guessing
+     (usleep 1000000) ;second frame starts here
+     (moveview -1.8101154154614007889 -8.2687205907162041209E-05)
+     ;just move the image
+     (usleep 1000000) ;third frame
+     (morphview -1.8101154154614007889 -8.2687205907162041209E-05
+     6.277210971069452361E-10 6.2772109785334669875E-10)
+     ;10 seconds of zooming into selected
+     rectangle
+     (usleep 100000000)
+
+   The best way to learn XaoS command language is probably to read
+position files and modify them. For example, to create zooming
+animation from the original file:
+
+     (initstate)
+     (defaultpalette 0)
+     (formula 'mandel)
+     (view -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+     9.69332308834E-08)
+
+   Just change the `view' command to `morphview', and add `usleep':
+
+     (initstate)
+     (defaultpalette 0)
+     (formula 'mandel)
+     (morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+     9.69332308834E-08)
+     (usleep 10000000)
+
+   The following code produces Julia morphing in the real axis:
+
+     (initstate)
+     (fastjulia #t)
+     (juliaseed -2 0)
+     (morphjulia 2 0)
+     (usleep 2000000)
+
+   And following is the "rotozooming" animation:
+
+     (initstate)
+     (fastrotate #t)
+     (morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+     9.69332308834E-08)
+     (morphangle 300)
+     (usleep 10000000)
+     (wait)
+     (fastrotate #f)
+
+6 XaoS gallery
+**************
+
+I plan to make a gallery of animations and position files on the XaoS
+home-page, so please send any nice animations and images you created
+using XaoS to the mailing list or upload them to our website.

+7 How to write XaoS help files
+******************************
+
+XaoS help is stored in the file `help/xaos.hlp'. It is divided into
+parts, each part being started by a _keyword_. In the help file
+keywords are written as `%keyword'
+
+   If you are writing documentation about some command in the XaoS
+function registry, use the same keyword as the name of the command in
+order to make context sensitive help work.

+7.1 xshl
+========
+
+_Xshl_ stands for _XaoS simple hypertext language_. It uses similar
+tags to HTML. It is simpler and more restrictive in order to make it
+easy to parse using various scripts. In C code you can use the library
+present in `src/util/xshl.c' to parse it.
+
+   The following tags are supported:
+
+*head*
+     make headings (should be at the beginning of the page, at least)
+
+*emph*

+8 Platform-specific documentation
+*********************************
+
+XaoS is portable and works on many different platforms. Since not all
+platforms are exactly the same, there are some differences between the
+behavior of XaoS on different platforms. Here is documentation about
+each specific port.

+
+8.1 AA-lib driver
+=================
+
+The AA driver is currently the most advanced and portable driver for
+XaoS.  It is based on AAlib--a high quality ASCII-art library developed
+by the AA-project.  (see `http://aa-project.sf.net')
+
+   It is a fully featured XaoS driver for text mode displays. It
+supports 256 colors and the mouse where possible.
+
+   It also has some extended features available from the UI menu:
+
+*Attributes*
+     AA-lib may use character attributes to improve image quality.  By
+     default it uses normal, dim and bold characters where possible,
+     but you can also enable different attributes like reversed or bold
+     font characters. You may also enable usage of non ansii/reversed
+     characters if your device supports it.
+
+*Font*
+     AA-lib uses a bitmap image of the font to prepare the
+     approximation table used for ASCII art rendering. This bitmap is
+     expected to be same as the one used by your device. AAlib performs
+     detection where possible however some devices (like UNIX text
+     terminals or MDA) do not support this. AAlib has few font images
+     compiled in, so in this case you should try to use one of them to
+     achieve best results.
+
+*Inversion*
+     Some devices use inverse video: use this to get correct results on
+     such devices.
+
+*Dithering mode*
+     Dithering is an way to get more exact color in approximations, by
+     combining more characters; but this method can produce ugly
+     looking noise on certain images.  Use this menu to disable or tune
+     it.
+
+*Palette options*
+     By default AA driver uses the XaoS palette to render images, but
+     it quite often looks ugly on text displays. Here you can choose a
+     special text palette instead. Note that with filters enabled, the
+     results may be rather ugly. This function is available from the
+     _palette menu_.
+
+*Save text screen*
+     The normal save function will generate a PNG image instead of nice
+     ASCII-art. To save ASCII art use this function instead. It
+     supports many text file formats like HTML, ANSI, more, etc... It
+     will also ask you for font and attributes(see above). It is
+     available from the _file menu_.
+
+   The AA-lib driver also provides the full set of standard AA-lib's
+command line options. You may use them to tune parameters like gamma
+correction, and so on.  See `xaos -help' or the AA-lib documentation
+for details.
+
+   The AA driver was written by Jan Hubicka, 1997.

+
+8.2 BeOS support
+================
+
+XaoS has pretty advanced support for BeOS R4. It works on both PowerPC
+and Intel platforms, supports multithreading, the clipboard, file
+dragging, has native look and feel and can work as an image translator
+from XaoS files to images.
+
+   The first version of the BeOS driver was written by Jens Kilian and
+later extended by Jan Hubicka.
+
+8.2.1 Installation
+------------------
+
+You can start the installation script to do everything for you. If you
+want something special, read this section.
+
+   In order for XaoS to work you need to keep the executable together
+with its data files (`help', `examples', `catalogs' and the `tutorials'
+directory)
+
+   When first started, XaoS registers two new mime types called
+`image/x-xaos-position' for XaoS Position Files and
+`video/x-xaos-animation' for XaoS Animation Files, registers icons for
+them and sets itself as default application.
+
+8.2.2 Available display drivers
+-------------------------------
+
+XaoS supports following drivers:
+
+*BeOS*
+     Standard windowed driver using application server
+
+*DirectWindow*
+     Driver done using Game Kit's direct window class
+
+*WindowScreen*
+     Fullscreen driver.
+
+   By default, XaoS starts in windowed mode and uses the application
+server for output.  You could change the driver to DirectWindow to use
+direct access to video RAM.  Note that this mode is slower in most
+cases, and not supported by some videocards.
+
+   The BeOS driver by default chooses the most similar bitmap supported
+by XaoS to achieve best and fastest results.  In the UI menu you can
+change this default choice to another one if you wish.  Also you can
+ask the BeOS and DirectWindow to resize to fullscreen mode.
+
+   XaoS also supports real fullscreen mode using the BWindowScreen API.
+To switch XaoS to this driver, use the UI menu. If you want to use this
+mode by default, use the `-driver WindowScreen' command line option.
+
+   This driver differs a lot from windowed ones. It use direct access
+to the video card, allowing you to change video mode. Also, the 256
+color mode can access the palette, so it is not dithered like the
+windowed mode.  Because BeOS can't do GUI in fullscreen mode, XaoS uses
+its own toolkit.  I hope you will feel confortable in it.
+
+8.2.3 XaoS as translator
+------------------------
+
+You should be able to open XaoS files in graphics applications such as
+ShowImage or ArtPaing. In Preferences you can find the DataTranslations
+program, that can be used to set the size, type and DPI of the
+resulting image.  Also antialiasing can be enabled.
+
+   Note that _translation can take a while_. So be patient and wait for
+the result.
+
+   If the translator doesn't work, ensure that you have a link to the
+XaoS executable in `/boot/beos/system/add-ons/Translators/'.

+
+8.3 DGA driver
+==============
+
+This is the driver for DGA (Direct Graphics Architecture) extension
+used by XFree86 X servers. It is pretty new so it could be buggy.
+
+   Bugs/limitations:
+
+*In 8bpp mode, XaoS has problems with the palette with certain window managers*
+     I don't know why this happens. Just let me know what's wrong, or
+     use another window manager.
+
+*Banked modes are not supported.*
+     I don't have any card to test this with, so it doesn't work in the
+     current version.
+
+   DGA driver was written by Jan Hubicka, 1999.

+File: xaos.info,  Node: dos,  Next: dX-fullscreen,  Prev: DGA,  Up: drivers
+
+8.4 DOS driver
+==============
+
+This is a fully featured driver for DJGPP and allegro.  It supports
+many VGA modes, VESA 1.0--3.0, VBE/AF, S3 and some other cards.
+
+   The following problems may occur:
+
+*Some DPMI servers may cause problems*
+     Some DPMI servers like the one from Novell/Dr/Open DOS are buggy.
+     Use clean DOS instead and XaoS will automatically start `cwsdpmi'.
+     Under Open Dr DOS use `dpmi off' at command line to disable it.
+
+*Higher resolutions don't work*
+     If your videocard has enough memory for the selected resolution,
+     you most probably have an unsupported videocard.  Please use a
+     VESA BIOS extension on this videocard. (See the note about VESA at
+     the end of this section.)
+
+*XaoS needs a coprocessor*
+     I don't distribute a coprocessor library linked into XaoS because
+     it is too slow for a real-time zoomer. Coprocessor emulation will
+     not help, because xaos works in protected mode.
+
+*XaoS needs mouse driver to be usable*
+
+*XaoS works slowly in higher resolution*
+     This could also be caused by Allegro's slow driver or your
+     videocard's VESA BIOS.  You could try some other VESA BIOS
+     extension instead.  Look at the `http://www.talula.demon.co.uk'
+     for the FreeBE project or Scitech Display Doctor package.  (See
+     the note about VESA at the end of this section.)
+
+8.4.1 VESA
+----------
+
+VESA is a standard for using higher resolutions in DOS. Many videocards
+have VESA support in the BIOS so you don't need any additional
+software, while others need support from a special program. Also some
+VESA BIOS implementations are buggy or suboptimal; there are 3
+different versions, version 1.0 is many times slower than 2.0, which
+has support for protected mode and linear framebuffers.  So if you have
+problems with higher resolutions, or some graphics modes are not
+available (like 320x200 truecolor), you might try some software package
+which emulates VESA.
+
+   The most famous VESA emulating program is Scitech Display Doctor. It
+has support for many videocards and is quite reliable. It's
+disadvantage is that it is shareware and works for only 30 days. You
+might also look on `ftp.simtel.net', where there are many VESA
+emulation packages such as `s3vbe' or the new FreeBe project at
+`http://www.talula.demon.co.uk'

+8.5 DirectX fullscreen driver
+=============================
+
+This is da river for Windows 9x and NT. It is new since version 3.1 and
+because of some oddities of Windows API and kludges in DirectX it may
+be rather unstable. Please report all bugs. In case of problems you
+could use the DOS version of XaoS instead.
+
+   This driver allows the Windows port of XaoS to run in full screen
+mode.  The driver supports 256, 65536 and 16777216 color modes (24bpp
+and 32bpp) in all resolutions supported by DirectX.  You can change
+graphics mode by pressing the `=' key (or by using the UI/Resize menu).
+If the selected mode is not supported, the driver will restore the
+previous setting.
+
+   Use the `-mode WIDTHxHEIGHTxDEPTH' (like `-mode 640x480x16') command
+line option to change graphics mode.
+
+   If you want to start XaoS in DirectX, use the `-driver dX-fullscreen'
+option.
+
+   See the Win32 driver documentation for some more Windows releated
+information.
+
+   DirectX driver was written by Jan Hubicka, Jan Olderdissen and Pavel
+Tzekov, 1999.

+
+8.6 GGI driver
+==============
+
+GGI stands for General Graphics Interface. Part of this project is to
+develop libggi, a portable graphics library, and XaoS's GGI driver uses
+that.  It is experimental, since the API of libggi is not stabilized
+yet.  There are some problems with keyboard handling--the shift key
+doesn't work yet.
+
+   Everything else might work well, but there are no guarantees. It is
+alpha quality software.
+
+   GGI driver was written by Jan Hubicka, 1998.
+
+
+File: xaos.info,  Node: plan9,  Next: SVGAlib,  Prev: ggi,  Up: drivers
+
+8.7 Plan9 driver
+================
+
+Plan9 is a very nice small operating system by the authors of Unix at
+Bell Labs.  It is very incompatible with other operating systems; even
+the C compiler and header files are different, but XaoS should work
+well there (even on the limited free demo installation without any
+POSIX compatibility stuff)
+
+   There are a few limitations: the file selector and image saving
+don't work.  You can save position files and then later render them on
+the other OS, or save screenshots.
+
+   Plan9 terminals also don't provide any way to catch the arrow keys,
+so you can't use them. Use the mouse to navigate in the menus. Also,
+getting the screen resolution is impossible, so use `-pixelwidth' and
+`-pixelheight' instead of `-screenwidth' and `-screenheight'.
+
+   By default XaoS changes the colormap. This will collide with other
+colorful programs like Mortha. You can disable this behavior using
+`-nopalette' switch, but this will slow down XaoS.
+
+   Plan9 driver was written by Jan Hubicka, 1997.

+
+8.8 SVGAlib driver
+==================
+
+This is a driver for Linux SVGAlib. I really like this driver, because
+I much prefer full screen zooming instead of a small 320x320 window in
+X11.  It was one of the first drivers for XaoS and is fully featured.
+The following problems can occur:
+
+*XaoS doesn't initialize graphics mode*
+     when started under users other than root SVGAlib requires root
+     privileges to directly access the hardware. When you really want
+     to start XaoS as a normal user, enable the suid bit (`chmod +s')
+     at XaoS executable.  note that I take care to disable all security
+     holes caused by this bit so I believe it is safe.
+
+*Mouse doesn't work*
+
+*Screen is blank at higher resolutions*
+     Both this problems are probably caused by misconfiguration of
+     SVGAlib. Please configure it in `etc/vga/libvga.cong' or
+     `/usr/local/lib/libvga.conf' GPM can also cause problems. Try to
+     kill it before starting XaoS.
+
+*When I switch console I can't switch back*
+     This is another typical SVGAlib bug. Try to hold `F' key longer
+     than `alt'.  It helps on my computer. On older SVGAlib there was a
+     famous "enter bug" that caused a crash after pressing enter. Try
+     to update to a newer release.
+

+
+8.9 Win32 driver
+================
+
+This is a driver for Windows 9x and NT. It is new since version 3.1 and
+because of some oddities of Windows API it may be rather unstable.
+Please report all bugs. In case of problems you could use the DOS
+version of XaoS instead.
+
+   The driver should work in all bit depths, but 16 color mode is not
+natively supported by the XaoS engine. XaoS internally works in 32k
+colors and the result is converted to 16 colors by Windows. Because
+Windows conversion routines are slow and ugly, the result is slow and
+ugly.  Please configure your display to another bit depth to "solve"
+this problem.
+
+   Use `-size WIDTHxHEIGHT' command line option to change the default
+window size.
+
+   This driver also maps to native Windows look and feel. There is a
+small problem with combo boxes in dialogs. They are expected to give
+you a choice between a few strings. The keyboard controls (changing
+choice by arrow keys) work, but mouse selection is broken. If you know
+how to solve this bug, please let me know.
+
+   XaoS is a UNIX application and has many command line options.  Some
+features are not available from the GUI.  Because Windows applications
+can't have normal output, most of the critical messages are displayed
+in message boxes, but some longer messages are omitted. The most
+significant omission is the help about command line options that you
+can find in `doc/cmdopts.txt'.
+
+   One thing that might be confusing is that animation rendering mode
+doesn't display anything, but only renders images. Start the rendering,
+and a message box will inform you that XaoS is entering the calculation
+loop. Relax and wait for the message box signaling the end of the loop.
+
+   Note that XaoS also supports the DirectX API.
+
+   Win32 driver was written by Jan Hubicka, Jan Olderdissen and Pavel
+Tzekov, 1999.

+
+8.10 X11 driver
+===============
+
+This was the first driver done for XaoS. It supports many visuals,
+shared colormaps and MitSHM extension.
+
+   Bugs/limitations:
+
+*XaoS makes some X servers too busy*
+     Sometimes XaoS generates images faster than X can display them.
+     In this case XaoS responds poorly to the mouse, and other
+     applications slow down too. This happens especially often on old
+     R4 servers. Use `-sync' to avoid this problem. Note that `-sync'
+     does `not' make all communication with X asynchronous; it just
+     adds one additional XSync call.  So the slowdown is not as large
+     as you might expect.
+
+*Does not work on all visuals*
+     This driver supports only 8bpp pseudocolor/grayscales, 15,16,24
+     and 32bpp truecolor, 1bpp and 8bpp staticolor visuals.
+
+*Palette rotating does not work for 8bpp pseudocolor w/o private palette*

+
+A.2.1 Include file
+------------------
+
+ -- Function: load file
+
+   This function lets you include another file in your script. It works
+similarly to `#include' in C or `load' in Scheme.  The file is searched
+for in the same directory as the current source file.
+
+   _Available as_: command
+
+
+File: xaos.info,  Node: linemenu,  Next: animf,  Prev: plc,  Up: menus
+
+A.3 Line drawing functions
+==========================
+
+XaoS has support for drawing lines. These functions are available only
+in animations and could be used to show some parts of fractals or draw
+simple diagrams. See the tutorial "Introduction to fractals" for
+examples of this feature.
+
+   Lines can be drawn in _screen_ coordinates, where 0,0 is the top
+left corner and 1,1 is bottom right, _scaled_ coordinates, which are
+similar, but scaled to keep 0,0--1,1 rectangular, or _Fractal_
+coordinates, to draw a line at an exact position on the screen.
+
+   The color of the line should be specified by the `color' command.
+You might draw an arbitrary number of lines and, later, morph them.
+Each line is identified by a unique numeric key; the current key can be
+set using `linekey'.  Commands for changing lines operate on the line
+with the current key.  (Lines drawn in sequence have consecutive
+numbers.)
+
+   For example:
+
+     (color 'red)
+     (line 'scaled 0.3 0.5 0.7 0.5)
+     (line 'scaled 0.3 0.5 0.7 0.5)
+     (line 'scaled 0.3 0.5 0.3 0.5)
+     (line 'scaled 0.7 0.5 0.7 0.5)
+     (linekey 0)
+     (morphline 'scaled 0.3 0.3 0.7 0.3)
+     (morphline 'scaled 0.3 0.7 0.7 0.7)
+     (morphline 'scaled 0.3 0.3 0.3 0.7)
+     (morphline 'scaled 0.7 0.3 0.7 0.7)
+     (usleep 1000000)
+
+   Creates line morphing to rectangle.
+
+ -- Function: line keyword complex complex
+
+   Draw line between two points.  `keyword' specifies type of
+coordinates and should be one of the following: ``fractal', ``screen'
+or ``scaled'.  This function also increases the line key.
+
+   _Available as_: command
+
+ -- Function: morphline keyword complex complex
+
+   Morph current line to given coordinates.  `keyword' specifies type
+of coordinates and should be one of the following: ``fractal',
+``screen' or ``scaled'.  The line will start moving at the next timing
+command, and reach the final position before the end of it.  This
+function also increases the line key.
+
+   _Available as_: command
+
+ -- Function: morphlastline keyword complex complex
+
+   This function has the same functionality as morphline, but it doesn't
+increase the line key, and touches the line with the previous key. This
+is useful when you want to move a just-drawn line--you don't need to
+set linekey back.
+
+   _Available as_: command
+
+ -- Function: linekey integer
+
+   Set current line key.
+
+   _Available as_: command
+
+ -- Function: clearline
+
+   Clear current line. This function also increases the line key.
+
+   _Available as_: command
+
+ -- Function: clearlines
+
+   Clear all displayed lines. Lines can also be cleared using the
+`clearscreen' or `display' commands available from the Misc menu. *Note

+A.4 Animation functions
+=======================
+
+These functions are used to animate fractal state--to zoom, unzoom and
+morph various parameters. They should be used only in animation files.
+Animations are usually performed for a time selected by an immediately
+following timing function. *Note time::.  For example:
+
+     (view 0 0 1 1)
+     (morphview 0 0 2 2)
+     (usleep 5000000)
+
+   Will do a 5 second long unzooming animation.
+

+
+A.4.1 Animate view
+------------------
+
+ -- Function: animateview float float float float
+
+   This function is almost identical to function `view'. *Note uiview::.
+It expects that the view will be changed only slightly, so
+recalculation is done with `ANIMATE' priority. This means that dynamic
+resolution is used by default.
+
+   Viewport is selected by the center and two radiuses (real and
+imaginary). See `view' for more information.
+
+   _Available as_: command

+
+A.4.2 Smooth Morphing
+---------------------
+
+ -- Function: morphview keystring starttime endtime
+This function lets you smoothly start and stop morphing. Specify
+starttime and stoptime as nonzero, and morphing will speed up and slow
+down for that number of usecs.
+
+   The keystring is used to select what morphing you want to control.
+It is one of the following:
+*'view*
+     control morphview
+
+*'angle*
+     control morphangle
+
+*'julia*
+     control morphjulia
+
+*'line*
+     control morphline
+
+
+File: xaos.info,  Node: morphview,  Next: morphjulia,  Prev: smoothmorph,  Up: animf
+
+A.4.3 Morph view
+----------------
+
+ -- Function: morphview float float float float
+For the time selected by the next `usleep' or other timing function,
+the viewpoint is smoothly morphed from the current one to that selected
+by `morphview'.
+
+   Viewport is selected by the center and two radiuses (real and
+imaginary). See `view' for more information.
+
+   This function can easily be used for creating zooming/unzooming
+animations using position files.  This is an example position file
+generated by XaoS:
+
+     (initstate)
+     (defaultpalette 0)
+     (formula 'mandel)
+     (view -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+     9.69332308834E-08)
+
+   By replacing the `view' command with `morphview' and adding `usleep'
+you can create a zooming animation:
+
+     (initstate)
+     (defaultpalette 0)
+     (formula 'mandel)
+     (morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08

+
+A.4.4 Morph Julia
+-----------------
+
+ -- Function: morphjulia complex
+For the time selected by the next `usleep' or other timing function,
+the Julia seed is smoothly interpolated from the current one to that
+selected by `morphjulia'. By default this will cause recalculation of
+the whole screen.  To avoid this, use fast Julia mode. *Note
+fastjulia::.
+
+   A simple animation morphing Julia seed in the X axis:
+
+     (initstate)
+     (fastjulia #t)
+     (juliaseed -2 0)
+     (morphjulia 2 0)
+     (usleep 2000000)

+
+File: xaos.info,  Node: morphangle,  Next: zoom,  Prev: moveview,  Up: animf
+
+A.4.6 Morph angle
+-----------------
+
+ -- Function: morphangle float
+Smoothly rotate the image to another angle. By default rotation causes
+recalculation of the whole screen. To avoid this you need to enable
+fast rotate mode. *Note rotate::. Don't forget to disable it later,
+since it slows down other animations.
+
+   A simple "rotozooming" animation:
+
+     (initstate)
+     (fastrotate #t)
+     (morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+     9.69332308834E-08)
+     (morphangle 300)

+
+A.4.7 Zooming functions
+-----------------------
+
+The functions for zooming/unzooming were created mainly for recording
+animations. In manually created animation files, it is easier to use
+`morphview'. *Note morphview::.
+

+A.5 Timing functions
+====================
+
+Timing functions are used to control the animation replay daemon. It
+can wait for a given time, or wait until calculation is complete. The
+animation functions are controlled by such waiting; animations that are
+running while delays start keep running through the delay.

+A.5.1 Usleep
+------------
+
+ -- Function: usleep integer
+
+   This function waits for a given amount of time (in usec) before
+processing the next command. The screen is recalculated and displayed
+at the beginning of usleep if necessary necessary. The remaining time

+A.5.2 Wait for text
+-------------------
+
+ -- Function: textsleep
+
+   This function's behavior is very similar to `usleep', but the time
+is calculated from the number of letters currently displayed onscreen.
+If you want to wait just long enough for the user to read the subtitle,
+use this function. The user can alter the replay speed as desired using
+`letterspersec'. *Note letterspersec::. This value can be changed during
+replay with the arrow keys.

+
+A.5.3 Wait for complete image
+-----------------------------
+
+ -- Function: wait
+
+   Wait until the image is complete. You should always use this
+function after zooming or unzooming when dynamic resolution is in use.
+This ensures that the image calculation will be complete so the user
+can see the result before the animation continues. It may also be
+useful in combination with filters like motion blur. *Note blur::.
+
+   This function deadlocks if used with animation functions; don't do
+that.

+
+A.8.2 Mandelbrot/Julia mode
+---------------------------
+
+Most fractals rendered by XaoS can be represented as Mandelbrot sets or
+Julias.  Each point in the Mandelbrot set has its own Julia set. To
+learn more about this correspondence, see the tutorial on the Julia set.
+
+   This function switches between Mandelbrot and Julia representations.
+When switching to Julia, you need to set the seed--a point selected
+from the Mandelbrot set.
+
+   If you run this function from the menu, you are prompted for the
+Julia seed as a number. Often, this can be clumsy, and it would be
+easier to specify a point with the mouse pointer. If you hit the `M'
+key instead of using the menu, the current mouse position is used.
+
+   Good seedpoints lie at the boundaries of the Mandelbrot set; other
+seeds usually generate quite a boring fractal. You can also explore
+various seeds at high speed using the Fast Julia mode. *Note
+fastjulia::.
+
+   Not all fractals have Julias, but XaoS can generate fake Julia sets
+for those that do not, which use some Julia-like modification of the
+formula; so this function is currently usable for all fractal types.
+
+   _Available as_: menu item
+
+ -- Function: julia bool
+
+   This function is used to enable/disable julia mode in animation
+files.

+
+A.8.3 Perturbation
+------------------
+
+Perturbation is a simple trick which changes the point at which orbits
+start.  Traditionally zero is used, but other values can generate
+interesting results too.
+
+   On enabling this function from the menu, you will be asked for a
+complex number specifying the perturbation. It is a toggle; selecting
+it again resets the perturbation to zero without prompting.
+
+   It can be used to specify a complex number representing a point on
+the screen.  If you hit the `B' key instead of using the menu, the
+current mouse position is used. This too is a toggle, so `B' again will
+disable perturbation by setting it to zero.
+
+   This function only has an effect for certain formulae (like the
+Mandelbrot set</a>) and only then in <a uimandelbrot>Mandelbrot mode.
+*Note mandel::.
+
+   _Available as_: menu item
+
+ -- Function: perturbation complex
+
+   This is the scripting-language variation of the perturbation
+function. Instead of toggling, you always specify the perturbation to
+use. Use 0 0 to disable perturbation.
+
+   _Available as_: command line option, command
+
+
+File: xaos.info,  Node: bailout,  Next: fastjulia,  Prev: maxiter,  Up: calc
+
+A.8.4 Bailout
+-------------
+
+Bailout is the value which is checked for each point of the orbit if
+the point is far enough from the complex zero point in the current
+iteration.  If the point is far enough, then the iteration immediately
+stops and the starting point on the screen will be painted with a given
+colour, depending on the fractal type and many other settings.
+
+   For the Mandelbrot set this value is 4. Other fractal types usually
+have the same bailout value. For most fractals many bailout values give
+more or less similar output. E.g., for the second order Mandelbrot set
+one can prove that the sequence |z| (z:=z^2+c) tends to infinity if and
+only if |z|>2 for some element z of this sequence.  In XaoS program,
+Bailout value is the square of this 2, i.e. you can change this to any
+value greater than 2 for similar results.
+
+   Other fractal types may use other bailout values. The default is 4
+for each types.

+
+A.8.5 View
+----------
+
+Set your current viewpoint in the fractal. This function is useful when
+you have found some interesting coordinates somewhere (on a web page,
+perhaps) and you want to see that position in XaoS.
+
+   In the dialog you will be asked for the _center_, _radius_ and
+_angle_ of the image.
+
+   The center specifies the point which is displayed at the center of
+the screen.  The radius is the radius of a circle around this point;
+XaoS will size the image so that this circle only just fits on the
+screen. The angle gives the rotation of the image in degrees.
+
+   People specify fractal coordinates in many ways. Some people use the
+coordinates of the upper-left and lower-right visible points,
+specifying the coordinates as four numbers x1, y1, x2, y2.  To set the
+same viewpoint in XaoS, set the real portion of the center to
+(x1+x2)/2, the imaginary part of center to (y1+y2)/2, and the radius to
+the greater of x2-x1 and y2-y1.
+
+   Other programs use a zoom factor instead of a radius. For these, you
+can set the radius to 2/zoom.
+
+   _Available as_: menu item
+
+ -- Function: view float float float float
+
+   This function is used to set the visible area of fractal in
+animation files.  It doesn't let let you specify the angle, (for that,
+see the separate function `angle'), but lets you specify an ellipse
+instead of a circle. You can specify both a real and an imaginary
+radius, so you have better control over the area that will be visible.
+XaoS will size the image so that the ellipse only just fits on the
+screen.
+
+   _Available as_: command line option, command
+
+ -- Function: angle float
+
+   Set the rotation angle in degrees. By default this causes
+recalculation of the screen. You can enable the fast rotation mode,
+which lets you rotate the screen without recalculation; but it slows
+down other things, so don't forget to disable it later.

+should also be used as the first command of every animation file, to

+A.8.7 Plane
+-----------
+
+ -- Function: plane integer
+
+   All fractals displayed by XaoS are functions with a complex
+parameter.  They can be be displayed in the normal complex plane where
+the `x' coordinate is the real part of the number and the `y' is
+imaginary; but they can also be displayed differently:
+*mu*
+     Normal complex plane (default)
+
+*1/mu*
+     Inversion--infinity is at 0 and 0 is at infinity.
+
+*1/(mu+0.25)*
+     Similar to inversion, but moves the center outside the Mandelbrot
+     set, so it looks parabolic.
+
+*lambda plane, 1/lambda, 1/lambda-1*
+     Lambda plane and its inversion, and with a different center.
+
+*1/(mu-1.40115)*
+     A very interesting mode for the Mandelbrot set, this makes small
+     things large, for easier browsing of the set's details.
+   The tutorial about planes has some examples.
+
+   In the scripting language, the planes are numbered as follows:

+
+A.8.8 Inside coloring mode
+--------------------------
+
+ -- Function: incoloring integer
+
+   Areas inside the set are usually filled in black, but this is only a
+convention; you could color them in differently to make the fractal
+look more interesting.  The only method available to make areas inside
+the set visible is to display the value of the latest orbit as the
+value of each pixel.
+
+   The tutorial on incoloring has more information and examples.
+
+   XaoS has many different ways to show that value. The cryptic names
+of the modes are mathematical formulae, where _real_ means the real
+part of the latest orbit, and _imag_ means the imaginary part. _zmag_
+uses the magnitude of the value. The _Decomposition-like_ method uses
+the angle of the orbit. Also, truecolor incoloring modes are available,
+that display one value in each of the red, blue and green color planes
+(or, for some modes, in each of the hue, saturation and value planes).
+
+   In the scripting language, the incoloring mode is specified by one
+of the following integers:
+
+*0*
+     0 (default)
+
+*1*
+     zmag

+
+A.8.9 Outside coloring mode
+---------------------------
+
+ -- Function: outcoloring integer
+
+   Outcoloring modes are similar to incoloring modes, but indicate how
+to display the areas outside the set instead. As with incoloring modes,
+the value of the latest orbit can be used to determine the color of
+each pixel, but the default is to use the number of iterations needed
+for the value at that point to become recognisably divergent as the
+color.
+
+   The tutorial on outcoloring has more information and examples.
+
+   The cryptic names of the modes are mathematical formulae, where
+_iter_ means the number of iterations required for the value to become
+recognisably divergent, _real_ means the real part of the latest orbit,
+and _imag_ means the imaginary part. _binary decomposition_ uses a
+different color when the imaginary part of the orbit is lower than
+zero, and _smooth_ attempts to remove stripes and discontinuities.
+Also, truecolor outcoloring modes are available, that display one value
+in each of the red, blue and green color planes (or, for some modes, in
+each of the hue, saturation and value planes).
+
+   In the scripting language, the outcoloring mode is specified by one
+of the following integers:
+
+*0*
+     iter (default)
+
+*1*
+     iter+real
+
+*2*
+     iter+imag

+
+A.8.10 Truecolor coloring mode
+------------------------------
+
+ -- Function: intcoloring integer
+
+ -- Function: outtcoloring integer
+
+   Truecolor coloring modes are similar to incolor and outcolor
+coloring modes; but instead of using a palette, they directly calculate
+the red, green and blue components of the color.  This lets you display
+more parameters at once, and produces interesting and often attractive
+results. On 8bpp displays you need to enable the palette emulator
+filter first to see anything, amd the quality won't be so good, as far
+fewer colors are available per parameter.
+
+   The tutorial on truecolor coloring modes has more information and
+examples.
+
+   The cryptic names of the modes are always three mathematical
+formulae (one for each color component), where _real_ means the real
+part of the latest orbit, and _imag_ means the imaginary part.
+
+   To enable inside/outside truecolor coloring mode in the scripting
+language, set `incoloring'/`outcoloring' value to 10 (truecolor coloring
+mode) before (or after) calling `intcoloring' or `outtcoloring'.
+
+   In the scripting language, the coloring mode is specified by one of
+the following integers:
+
+*0*
+     black
+
+*1*

+
+A.9.1 Solid guessing range
+--------------------------
+
+ -- Function: range integer
+
+   XaoS has a solid guessing optimization: if all corners of a
+rectangle have the same color, it assumes that the whole rectangle is a
+solid colored block, and doesn't calculate points inside the rectangle.
+This optimization saves lots of calculation, but sometimes introduces
+errors. This value alters the maximum size of the rectangle that can be
+guessed at one time. The default value is 3; use 0 to disable the
+optimization.

+
+A.9.2 Periodicity checking
+--------------------------
+
+ -- Function: periodicity bool
+
+   Periodicity checking is one way to speed up the calculation. Areas
+inside the set always need `maxiter' iterations to determine that the
+point is probably inside the set (while it is rare for areas outside to
+need anywhere near that much). Often the orbital trajectory falls into a
+periodic, repeating cycle; if that can be detected, the calculation can
+be stopped early, as there's no way that the orbit can ever leave the
+cycle again (hence it cannot diverge, hence the point must be inside
+the set).
+
+   Implementating this method efficiently is quite problematic. It
+slows down the cases where cycles are not found, because cycle-checking
+is quite hard work and has to take place for all points, even those
+that don't become cyclic.  Because of the inexactness of floating-point
+calculations, the cycles are never exact, so you need to use an error
+value. Higher error values mean that cycles will be detected sooner,
+while lower error values increase the exactness of the calculation.
+Higher values can introduce serious errors, especially at the front of
+the Mandelbrot set. XaoS detects this automatically and corrects for it
+in most cases, but sometimes it might be wrong. Also, other
+optimizations in XaoS (such as boundary tracing) don't give this method
+much of a chance to run, since areas inside the set are usually not
+calculated at all.
+
+   That's why the advantages of this optimization are questionable. You
+should probably experiment with enabling and disabling it. Sometimes
+XaoS is faster with this enabled, sometimes when disabled. Also, this
+method works only when incoloring methods are disabled, and only for
+some fractal types (some fractal types, e.g. newton, don't have any
+concept of an area `inside the set' at all.)
+
+   The tutorial chapter "Escape time fractals" has more information on
+fractal calculation in XaoS, and there is a lengthy section in the
+hacker's manual (`xaosdev.texinfo') devoted to the subject.

+A.9.3 Iterations
+----------------
+
+ -- Function: maxiter integer
+
+   When the fractal set is calculated, a orbital trajectory is examined
+for each point. If the orbit diverges to infinity, the point is outside
+the set.  Otherwise, the point is inside the set. For exact
+calculations, you need to know the entire orbital trajectory, which is
+infinitely long for areas inside the set, so fractals cannot be
+calculated exactly. By default, XaoS calculates at most 170 positions
+(iterations) and then gives up; if the point is still inside the
+bail-out value, it guesses that the point is inside the set.
+
+   When zoomed into a detailed area, especially one close to the set
+boundary, this value could become too low, and the fractal will become
+boring.  You might try increasing this value if you want to get the
+image interesting again; but this necessarily slows down the
+calculation at the same time.

+A.9.4 Fast Julia mode
+---------------------
+
+ -- Function: fastjulia bool
+
+   By default, changing the seed for the Julia set requires
+recalculation of the image (which is quite slow). It's a nice effect to
+change the seed smoothly and show the Julia set morphing as the seed
+changes. XaoS has a special algorithm which can calculate such
+morphings in realtime. It is very inexact, but it is good enough for a
+fast preview.
+
+   If you want to select a good seedpoint, enable fast Julia mode and
+find a nice place by dragging with the first mouse button depressed;
+then change to the Julia mode to see the exact image.

+A.10 Dynamic resolution
+=======================
+
+ -- Function: fastmode keyword
+
+   XaoS performs many optimizations, but fairly often this is not
+enough. In order to keep a high framerate, XaoS automatically lowers
+the resolution of the image, increasing it when there is time for more
+calculation. This feature is enabled by default when animating, but you
+might also like to enable it for new images (which makes the image
+`come into focus' when it is recalculated from scratch for whatever
+reason), or disable it completely if you don't like it.
+
+   In the scripting languge, the keyword should be one of the following:
+*`'never'*
+     Disable dynamic resolution
+
+*`'animate'*
+     Use only for animations (default)
+
+*`'new'*
+     Use also for new images
+
+
+File: xaos.info,  Node: rotate,  Prev: dynamic,  Up: calc
+
+A.11 Image rotation
+===================
+
+XaoS has support for rotation of the image to any angle. By default,
+changing the angle requires recalculation of the whole screen, but when
+_fast rotation mode_ is enabled, the angle can be changed smoothly.  In
+this mode XaoS calculates a larger non-rotated image and rotates it when
+needed, so it increases memory requirements and slows XaoS down; hence,
+it should be disabled when rotation is not being used.
+
+   The user interface provides two rotation modes--_rotate by mouse_
+which allows the angle to be changed by dragging with the first mouse
+button depressed, and _continuous rotation mode_, where the image is
+rotated clockwise continuously, and the arrow keys can be used to change
+the rotiation speed.

+A.12 Filters

+things. There is a tutorial chapter about them.

+
+A.12.5 Random dot stereogram
+----------------------------
+
+Fractal images are good as a base for random dot stereograms. In case
+you don't know what these are, please point your browser to Google or
+another search engine and find some articles about such images, because
+learning to read such images takes some effort. They make it possible
+to generate three dimensional images on a normal monitor without any
+additional hardware, by exploiting bugs in the human brain (although
+you need two working eyes, and some people never learn to see them;
+they can simply ignore this feature).
+
+   XaoS is able to generate these images in animations, so you may use
+all normal XaoS functions (except palette changing and palette rotation,
+which makes no sense applied to a stereogram). To make the animation yet
+more exciting, XaoS emulates "falling" into the set; while you zoom in,
+your distance from the set drops and drops--but you never hit it; when
+the set reaches the level of your monitor, the distance is changed
+again so you are far away.
+
+   To make this work right, XaoS needs to know the _exact size of your
+monitor_. Because most platforms have no way to determine this, you
+need to use _command line options_ to tune it. If it's not set or is
+wrong, the stereograms will probably be impossible to see (if your
+monitor is too big or resolution too low), or the images will seem to
+be shallow (if your monitor is too small or resolution too high).
+
+   By default XaoS expects my 15" monitor (29.0cm x 21.5 cm). Another
+cause of problems is the virtual screen supported by some windowed
+environments (like some X servers) that makes a program think that the
+resolution is higher than it actually is, and you see only part of this
+extra-large screen.
+
+   The worst thing you could possibly do is to run full-screen XaoS in
+some graphical windowing system (OS/2 on top of Windows or Wine on top
+of Linux, perhaps) where XaoS can't tell the real size of its window at
+all. In such cases, it's normally better (not to mention faster) to run
+XaoS natively, rather than under such an emulation layer.
+
+   The following command line options are provided to specify sizes:
+
+*`-screenwidth', `-screenheight'*
+     Lets you specify the size of your screen in centimeters. Note that
+     you need to specify the size of the visible image on the monitor,
+     not the size with edge borders, or the size of the tube. The
+     simplistic `my monitor is 17", just turn 17" into centimeters'
+     doesn't work; that 17" is a marketing figure and has only a vague
+     connection to reality. Get out a ruler and measure it.
+
+*`-pixelwidth', `-pixelheight'*
+     Lets you specify the exact size of a single pixel, if XaoS cannot
+     determine this for itself from your screen size.
+
+   These options are used by some other parts of XaoS as well, so you
+should use them even when you don't want to see stereograms. You should
+probably write a small starting script (or alias, or shortcut; whatever
+your environment uses) that passes the correct parameters to XaoS.
+
+   If the window is _smaller than 8cm in any direction_, you will
+probably be unable to see anything; make the window bigger.
+
+   The correct way to see XaoS stereograms is:
+*1*
+     Start XaoS with options specifying the exact size of your screen
+     or one pixel on it
+
+*2*
+     Sit 60cm away from monitor
+
+*3*
+     If you use a windowed environment, resize XaoS's window to make it
+     wider than, say, 15 cm.
+
+*4*
+     Enable the filter (by pressing `E')
+
+*5*
+     focus on a point far away from the monitor (try to use your own
+     reflection, if your monitor's not antireflective); the random
+     blurring should eventually fall into the pattern of a Mandelbrot
+     set.
+
+*6*
+     Carefully use your mouse to zoom into interesting areas (it is
+     easy to lose concentration when you are not trained; but you can
+     use the autopilot...)
+
+*7*
+     Enjoy animation :)
+
+   If you still can't see the stereograms, it could be that the
+fractal, or your eye, is deformed. A deformed fractal can be caused by
+your specifying your monitor size wrongly. Visual problems that damage
+depth perception, as well as problems like astigmatism, can make it
+impossible to see stereograms at all.

+A.12.6 Interlace filter
+-----------------------
+
+The interlace filter halves the horizontal resolution, and in each

+
+Motion blur mixes the current frame with previous ones to produce a

+to enable the palette filter first.

+A.12.9 Palette emulator
+-----------------------
+
+XaoS can work in either palette or truecolor mode. Both modes have
+advantages and disadvantages. Palette mode allows effects such as
+palette rotation, while truecolor mode allows smoother incoloring and
+outcoloring modes and the truecolor coloring modes. If your display is
+truecolor, you can enable this filter to get palette emulation (albeit
+not as cheaply as in a real paletted mode).

+
+A.12.10 Antialiasing
+--------------------
+
+Antialiasing is a technique to increase image quality by eliminating
+jagged edges. XaoS calculates four values for each pixel (on the
+subpixel boundaries) and uses the average of them for the pixel value.
+
+   This filter slows XaoS down a _lot_ and greatly increases memory
+requirements. It is useful mainly when you want to save images and want
+to make them look as nice as possible. Antialiasing also helps a lot
+when you want to encode JPEG or MPEG files; they are much shorter if
+antialiased (MPEG and JPEG hate jagged edges).

+A.12.11 Truecolor emulator

+
+XaoS can work in either palette or truecolor mode. Both modes have
+advantages and disadvantages. Palette mode allows effects such as
+palette rotation, while truecolor mode allows smoother incoloring and
+outcoloring modes and the truecolor coloring modes. If your display is
+8bpp, you can enable this filter to get truecolor emulation (but,
+obviously, not with as many colors as a real truecolor display).

+
+Each escape time fractal has its own formula. XaoS supports the
+following formulae:
+
+* Menu:
+
+* mandel::	Mandelbrot
+* mandel3::	Mandelbrot^3
+* octal::	Octal

+* magnet::	Magnet
+
+
+File: xaos.info,  Node: mandel,  Next: mandel3,  Up: mformula
+
+A.18.1 Mandelbrot
+-----------------
+
+The Mandelbrot set is the most famous escape time fractal ever. It has
+the simple formula z=z^2+c. See the tutorial chapter.
+
+   _Available as_: menu item, command line option
+
+
+File: xaos.info,  Node: mandel3,  Next: octal,  Prev: mandel,  Up: mformula
+
+A.18.2 Mandelbrot^3--Mandelbrot^6 and Mandelbrot^9
+--------------------------------------------------
+
+The Mandelbrot^3 fractal is a simple modification of the standard
+Mandelbrot set formula, using z=z^3+c instead of z=z^2+c.
+
+   Other derivations of the Mandelbrot set (Mandelbrot^4 and so on) use
+even higher powers. See the tutorial chapter.
+
+   _Available as_: menu item, command line option
+
+
+File: xaos.info,  Node: octal,  Next: newton,  Prev: mandel3,  Up: mformula
+
+A.18.3 Octal
+------------
+
+This is a less well-known fractal that Thomas discovered in Fractint.
+It has an interesting shape when displayed in the alternative planes.
+*Note plane::. See the tutorial chapter.
+
+   _Available as_: menu item, command line option
+
+
+File: xaos.info,  Node: newton,  Next: barnsley,  Prev: octal,  Up: mformula
+
+A.18.4 Newton
+-------------
+
+This is Newton's approximation method for finding the roots of a
+polynomial. It uses the polynomial x^3=1 and counts the number of
+iterations needed to reach the approximate value of the root. See the
+tutorial chapter.
+
+   This fractal doesn't have Julia sets, but XaoS is able to generate
+Julia-like sets which are also very interesting (they are sometimes
+called "Nova formulae").
+
+   _Available as_: menu item, command line option
+
+
+File: xaos.info,  Node: barnsley,  Next: phoenix,  Prev: newton,  Up: mformula
+
+A.18.5 Barnsley1
+----------------
+
+This is a formula by Michael Barnsley. It produces very nice
+crystalline Julia sets. See the tutorial chapter.
+
+   _Available as_: menu item, command line option
+
+
+File: xaos.info,  Node: phoenix,  Next: magnet,  Prev: barnsley,  Up: mformula

+File: xaos.info,  Node: magnet,  Prev: phoenix,  Up: mformula
+
+A.18.7 Magnet
+-------------
+
+This is a formula that comes from theoretical physics.  It is derived
+from the study of theoretical lattices in the context of magnetic
+renormalization transformations.  See the tutorial chapter.

+A.19 Palette
+============
+
+This menu contains functions to change the palette the fractal is
+displayed with.
+
+* Menu:
+
+* defpalette::	Default palette
+* randompalette::	Random palette
+* palette::	Custom palette
+* cycling::	Color cycling
+* shiftpalette::	Shift palette
+
+
+File: xaos.info,  Node: defpalette,  Next: randompalette,  Up: palettemenu
+
+A.19.1 Default palette
+----------------------
+
+ -- Function: defaultpalette number
+
+   Create a default palette. In the scripting language, `number'
+specifies how much the palette is shifted by.
+
+   Note that changing the palette in truecolor modes forces
+recalculation of the whole screen. To avoid this, you can enable the
+palette emulation filter first.
+
+   _Available as_: menu item, command line option, command
+
+
+File: xaos.info,  Node: randompalette,  Next: palette,  Prev: defpalette,  Up: palettemenu
+
+A.19.2 Random palette
+---------------------
+
+ -- Function: randompalette
+
+   Create a random palette. XaoS will automatically pick one of its
+palette-generation algorithms and create one.
+
+   Note that changing the palette in truecolor modes forces
+recalculation of the whole screen. To avoid this, you can enable the
+palette emulation filter first.
+
+   _Available as_: menu item, command line option, command
+
+
+File: xaos.info,  Node: palette,  Next: cycling,  Prev: randompalette,  Up: palettemenu
+
+A.19.3 Custom palette
+---------------------
+
+ -- Function: palette integer integer integer
+
+   A custom palette lets you re-create some of the random palettes. The
+first value specifies the algorithm, which should currently be one of
+the following:
+*0*
+     Default palette
+
+*1*
+     Black to color gradient
+
+*2*
+     Black to color to white gradient
+
+*3*
+     Cubistic-like algorithm.
+   The seed specifies a random seed for the palette; different seeds
+generate different palettes. The last value is the amount by which the
+palette is shifted.
+
+   Note that changing the palette in the truecolor modes forces
+recalculation of the whole screen. To avoid this, you can enable the
+palette emulation filter first.
+
+   _Available as_: menu item, command line option, command
+
+
+File: xaos.info,  Node: cycling,  Next: shiftpalette,  Prev: palette,  Up: palettemenu
+
+A.19.4 Color cycling
+--------------------
+
+ -- Function: cycling bool
+
+   Color cycling is an old and simple effect to animate fractals. The
+Mandelbrot set looks particularly nice when color-cycled. On truecolor
+displays, color cycling fails to initialize (since those displays don't
+have a palette).  You can enable palette emulation filter to make it
+possible.
+
+   _Available as_: menu item, command line option, command
+
+   In the user interface, colors can also be cycled in the opposite
+direction with the "_Reversed color cycling_" function.
+
+   To control the cycling speed, you coan use arrow keys or the "_Color
+cycling speed_" function.
+
+   _Available as_: menu item
+
+ -- Function: cyclingspeed integer
+
+   The parameter specifies the number of skips per second. It can be
+negative to cycle in the opposite direction.
+
+   _Available as_: menu item, command line option, command
+
+
+File: xaos.info,  Node: shiftpalette,  Prev: cycling,  Up: palettemenu
+
+A.19.5 Shift palette
+--------------------
+
+ -- Function: shiftpalette integer
+
+   Shift palette by the specified number of cells. This can be used to
+tune the palette's position on the fractal. You can also use the _Shift
+one forward_ and _Shift one backward_ functions for fine-tuning. Note
+that shifted and rotated palettes could look different on different
+displays (because they may have different palette sizes).
+
+   Shifting the palette on truecolor displays causes a recalculation of
+the screen.  To avoid this, you could use palette emulation filter.
+*Note palettef::.

+@section Why yet another fractal generator?
+
+
+We decided to make XaoS, because all fractal browsers we know of take a
+long time to calculate each image. You may browse nice images
+generated by them but real impressions of fractals --- the self
+similarity and infinite zooming into the nice parts of fractals ---
+can be seen only in animations. There are many programs available that
+make nice animations, but they take a long time to calculate and lots
+of space on disk. Most such animations are quite ugly because their
+authors can't see them without many hours of calculations.
+
+A natural question is: is it possible to generate such animations in
+real-time? The answer was negative for many years, since the Mandelbrot set is
+very computationally expensive. Things are changing. Today's computers
+are fast enough to calculate approx. 10.000 of pixels per frame,
+which is enough 
+for a very low resolution animation (100x100). Several programs doing that
+are available. But 100x100 animation still looks quite ugly. To make
+animation nice you need at least 320x200 pixels. And that is 6 times more!
+One possibility is to wait until computers will be fast enough, but
+it will take many years, and then 320x200 animations will be obsolete
+and everyone will want 1024x768 resolution instead or more.
+
+We found a special algorithm that saves up to 99.98% of calculations during
+zooming by reusing pixels already calculated in previous frames. There were
+some programs doing similiar tricks before but we don't know about any able
+to do zooming interactively with a speed similar to XaoS. Many other tricks
+were later implemented XaoS to achieve yet higher framerates. Now XaoS does
+up to 120 frames per second on a 120Mhz pentium in a fullscreen 320x200
+animation, and calculates an average of 160 (0.24%) pixels per frame. This makes
+XaoS fast enough to achieve its primary goal, realtime animation, but there
+are still many areas that could improve, since more complex fractals,
+higher resolutions, or slower computers still bring many problems.

+@section What does this software do then?
+
+XaoS is a realtime interactive fractal zoomer. This means that it lets you
+zoom smoothly into any place in the fractal you choose without the many hours
+of calculation required by most other fractal generators. It now has many
+other features too, like 13 different fractal types, autopilot, special coloring
+modes, support for various bit depths (8bpp, truecolor, hicolor and realcolor),
+random palette generation, color cycling etc...
+
+@c %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+@node tutorial, controls, Overview, Top
+
+@chapter XaoS tutorial
+
+This is a brief introduction to the basic XaoS features.
+
+@section How to zoom
+The main advantage of XaoS is that after a few seconds' delay to calculate
+the first image, you may choose any point with the mouse and press the @emph{left} button.
+The image will start to zoom smoothly into the point you choose. You may move
+the mouse and zoom smoothly into interesting areas. By pressing the @emph{middle
+button} (or @emph{left+right} buttons) you may also
+@emph{move the image} using ``drag & drop'' if you missed an interesting
+place. @emph{Unzooming} is also possible by using the @emph{right button},
+but it is much slower because optimizations are not so effective as for zooming.
+
+In case you think that the default @emph{speed} is boring (it is quite slow, to
+make XaoS smooth on a slow computer) you may change it by pressing @emph{arrow
+up/down}. But faster zooming is more expensive, so if the speed is too high
+you will see little but funny colorful blinking rectangles.
+
+@section Autopilot
+
+To make XaoS yet more impressive we made a special autopilot that
+automatically drives into interesting boundaries of the set. So you can
+press @code{A}, play your favorite music, drink coffee and relax. I never
+tried this but it should be really relaxing! Many pictures in the XaoS
+gallery were discovered using the autopilot.
+
+The autopilot also has some additional features. It turns back when the
+zoomed picture stops being interesting, and is able to spot when it's zoomed
+into a really boring part (or has reached the limit of floating point
+numbers) and restart zooming from the top.
+
+@section Various fractal formulae
+
+XaoS also supports formulae other than the Mandelbrot set. You may change
+@emph{formula} using the @emph{number keys}
+or @emph{SHIFT+letters}.
+
+
+
+On keys @code{1} to @code{5} are @emph{Mandelbrot sets of various power}. The ``normal''
+Mandelbrot set is on key @code{1}.
+
+On key @code{6} is a fractal called @emph{Newton}. It is Newton's famous formula for finding roots.
+
+On key @code{7} is the @emph{fourth ordered Newton} fractal.
+
+On key @code{8} is a fractal called @emph{Barnsley}.
+
+On key @code{9} is @emph{Barnsley's second} fractal.
+
+On key @code{0} is @emph{Barnsley's third} fractal.
+
+With keys @code{SHIFT-A} you can display a fractal called @emph{octo}. It is a fractal that Thomas
+discovered in fractint.
+
+With keys @code{SHIFT-B} you can display a fractal called @emph{Phoenix}. It is a very nice and quite famous fractal.
+
+With keys @code{SHIFT-C} you can display a fractal called @emph{Magnet}. This fractal has quite a complex formula so it is
+a bit slow.
+
+With keys @code{SHIFT-D} you can display the @emph{Magnet2} fractal.
+
+The rest of the built-in fractals are accessible through an other menu, but
+you can still use the hotkeys.
+
+On @code{SHIFT-E} is a fractal called @emph{Triceratops} found by Arpad.
+
+On @code{SHIFT-F} is a fractal called @emph{Catseye} found by Arpad.
+This is more interesting if you change the bailout value.
+
+On @code{SHIFT-G} is a fractal called @emph{Mandelbar}. It was in
+Gnofract4d, and they found it at:
+http://mathworld.wolfram.com/MandelbarSet.html
+
+On @code{SHIFT-H} is the @emph{Lambda} fractal.
+
+On @code{SHIFT-I} and @code{SHIFT-J} are the @emph{Manowar}
+and @emph{Spider} fractals, they were found by users of fractint.
+(Scott Taylor or Lee Skinner)
+It was on http://spanky.triumf.ca/www/fractint/
+taylor_skinner_type.html
+
+The next 3 fractals are famous classic fractals.
+
+On @code{SHIFT-K} is the @emph{Sierpinski} Gasket.
+You can change its shape by selecting another Julia seed.
+(This is for technical reasons.)
+
+On @code{SHIFT-L} is the @emph{Sierpinski Carpet.}
+It's shape can also be changed by selecting another Julia seed.
+
+On @code{SHIFT-M} is the @emph{Koch Snowflake.}
+
+
+
+@section Out-coloring modes
+
+To make fractals yet more interesting, more coloring modes for points
+outside the set are provided. ``Classical coloring mode'' uses the number of
+iterations that the orbit required to escape to (nearly) infinity. You can change this
+mode from the @emph{Fractal menu} or by pressing key @code{C}
+To see more about coloring modes, try the tutorial on Incoloring modes from the XaoS features overview.
+
+Those cryptic names for coloring modes are mathematical formulae, where @emph{iter} means number
+of iterations, @emph{real} means real coordinate of last orbit, and @emph{imag} means imaginary
+coordinate of last orbit.
+
+@section In-coloring mode
+
+In-coloring mode is similar to out-coloring, except that it changes how
+things inside the set are displayed. This can also be changed from the @emph{fractal
+menu} or by pressing @code{F}.
+
+You might also want to see the tutorial on
+Out-coloring modes from the XaoS features overview.
+
+@section Planes
+
+All fractals displayed by XaoS are functions with a complex parameter. It
+can be displayed in the normal complex plane, where x is the real part of
+the number, and y is the imaginary part; but it can also be displayed in
+a number of other planes. You can select the plane to use from the
+@emph{Fractal menu}, or by pressing @code{I}.
+
+Like the coloring modes, planes have cryptic names. You guessed it, they're
+mathematical formulae. Here @code{mu} means coordinates in the normal
+complex plane. If you have coordinates in @code{1/mu} plane, and you need
+coordinates in the a complex plane (to calculate the Mandelbrot set) you
+simply use the coordinates as mu. Lambda is another plane that can be
+converted to mu using a similar formula.
+
+@table @strong
+@item mu
+normal mode.
+
+@item 1/mu
+Inversion: infinity goes to 0 and 0 goes to infinity.
+
+@item 1/(mu+0.25)
+Similar to inversion, but moves the center outside of the
+Mandelbrot set so that it looks parabolic.
+
+@item lambda
+Lambda plane.
+
+@item 1/lambda
+Inversion of lambda plane.
+
+@item 1/lambda-1
+Inversion with moved center.
+
+@item 1/(mu-1.40115)
+A very interesting mode for the Mandelbrot set. It makes small things
+big, so you can browse the set's details easily.
+@end table
+
+
+@section Mandelbrot/Julia switching
+
+Most of the fractals displayed by XaoS (currently all of them) have two
+forms: Mandelbrot and Julia. Every point in a Mandelbrot set has its
+own Julia set. To see more about this correspondence, try the tutorial on
+Julia set from the Introduction to fractals.
+
+In the Mandelbrot mode, you can get a corresponding Julia by moving the mouse
+to an interesting point and pressing @code{M}. To get back press @code{M}
+again. Some fractals (Barnsley and phoenix) are already in their Julia
+versions, because the Mandelbrot ones are boring. But by pressing @code{M}
+in such fractal you should get the Mandelbrot version, and by choosing another
+point as the base point and pressing @code{M} again you should get a
+completely different fractal. The most interesting points for Julia sets
+are at the boundaries of the Mandelbrot set. Most of the Julias inside or
+outside the set are boring.
+
+
+@section Fast Julia preview mode
+
+Fast Julia mode is a quick way to find a point to use as a base for the Julia
+set.. Just press @code{J} and a small Julia set will be displayed in the top
+left corner. Then move the mouse around with button 1 depressed, and the Julia
+for the point the mouse is over will be automatically generated.
+
+@section Palette
+
+If you think that the default XaoS colors are ugly or you are just
+bored by them you can change it by pressing @code{P}. XaoS will
+automatically generate random palettes. Many of them look ugly, so
+press @code{P} again to get another one until you find one you like.
+
+@section Filters
+
+Many interesting effects are done by post-calculation filters. @xref{filter}.
+XaoS has filters that do everything from embossing, through motion-blurring,
+right through to turning the fractal into a stereogram. To enable them use
+the @code{filter menu} or press @code{E}.
+
+@section Palette cycling
+
+This is a very old trick that makes the Mandelbrot set a little flashier. You
+may enable or disable it using @code{Y}. In the truecolor modes you need
+to enable the palette emulator filter first. This is done
+via the @code{E} key, or from the filter menu.
+
+@section Changing number of iterations
+
+To calculate fractals perfectly, you need an infinite number of
+iterations. XaoS does just the first few of them, so after lots of zooming
+you may get into a place that looks quite boring, and the boundaries of the
+set are rounded, without any interesting details. This can be changed by
+changing the number of iterations:
+
+Press and hold @code{arrow right} and wait until iterations are high enough.
+This may slow down calculation much. To reduce number of iterations
+press @code{arrow left}.
+
+@section Changing resolution
+
+XaoS usually starts in a low resolution (320x200 or thereabouts) to make
+calculations faster. If you have a fast computer or you need to
+save bigger @code{.gif} images, you may change the resolution. This
+can be done by pressing @code{=} in the full screen drivers, or simply
+by resizing the XaoS window.
+
+@section Changing driver
+
+XaoS usually has more than one driver available. You may change it on
+the fly in case you want a different one. For example, XaoS started in X11
+can be switched at runtime to use the AA driver. This can be done from the
+UI menu.
+
+This action is bit dangerous, because XaoS can crash during initialization
+if there is some problem with initialization; XaoS tries to initialize a new
+driver, and if it fails it attempts to return back to the original. Sometimes
+this is impossible, and all XaoS can do is terminate..
+
+@section Other features
+XaoS has many other features, but they don't fit into this tutorial. Most of
+them are available from the menu, so you can experiment with them. You might
+also want to see the @emph{animated tutorials} from the @emph{help menu},
+to have an idea what XaoS can do.

+@chapter Basic controls
+By default the mouse buttons work in the following way:
+
+@table @strong
+@item left
+zoom in
+@item right
+zoom out
+@item middle
+move fractal in a drag-and-drop fashion
+@end table
+
+@emph{Note:} Since most Macs only have one button mice, these controls
+are emulated on Mac OS X using modifier keys. See the help section on
+Mac OS X for details.
+
+This behavior can change. If you enable rotation, the first button is used for rotating
+fractals. Also, in fast Julia mode, the first button is used to change the seed.
+
+If you don't have a middle button, press both buttons to enable
+emulation.
+
+After few minutes of zooming you will probably exceed the precision and the
+fractals will get boring. If you are getting strange big rectangles on the screen,
+you probably reached the numeric limit: there is no way to avoid this except
+un-zoom back and choose a different area. It doesn't hurt so much, since you have
+zoomed approximately 64 051 194 700 380 384 times, so there are quite a lot of areas to
+explore. Algorithms with unlimited precision exist, but they are still too
+slow for real-time zooming.
+
+The other possibility is that you have reached the iteration limit. The fractal is
+calculated approximately, and in this case you need to increase number of
+iterations used for approximation (and decrease the speed in the process).
+This is done from the menu or using the arrow keys @emph{Left} and @emph{Right}.
+
+An @emph{Up} and @emph{Down} keys should be used to change zooming
+speed. Note that higher speed costs more and image will be blocky.
+
+This behavior can also change. With palette cycling enabled, @emph{Left}
+and @emph{Right} keys change cycling speed; in continuous
+rotation they change rotation speed.
+
+All other functions are available from the menu, which (in the default
+configuration) are displayed when you move the mouse to the top of the
+screen/window. It is useful to learn the shortcut keys, which are
+shown in gray next to the menu items they trigger.

+@chapter How to encode video files from XaoS
+
+To create a video, make and @code{xaf} file first (the easiest way to do this is
+to use the @emph{record} function in the file menu). Then you need to render
+the animation. XaoS can output sequences of ordinary @code{PNG} images, that
+can later be used by a video encoder.
+
+@section Generating image sequences for video
+
+To generate an image sequence, choose @emph{Render Animation} from the @emph{Misc}
+menu. You can also use the following command on the command line:
+
+
+@example
+xaos -render [filename] -size 352x240 -antialiasing
+-renderframerate 24 -basename [basename]
+@end example
+
+
+@emph{File to render} (@code{[filename]}) is the name of the @code{xaf} file,
+@emph{Basename} (@code{[basename]}) is the name used as the base filename for rendered images. This should also include the path where you want to save the images.
+XaoS adds a four digit sequence number and @code{.png} extension to this name automatically.
+
+You might also want to change the resolution. Make sure that the resolution
+you choose is supported by the video codec you wish to use.
+
+The framerate can also be altered. Make sure you choose a framerate that is supported by
+the video codec you wish to use.
+
+@emph{Antialiasing} (@code{-antialiasing}) is used to produce anti-aliased images.
+It takes a much longer
+time and much more memory to calculate them, but resulting images are better
+for video compression and they result in a much smaller video file.
+(the same is true of @emph{JPEG images})
+
+On the other hand, the other XaoS rendering option @emph{Always Recalculate} (@code{-alwaysrecalc}) (which disables
+XaoS's zooming optimizations) is @emph{not recommended}. If that's used, the
+sequence of animation then contains quite a lot of extra information, which
+increases size of video file, but because of the codec's lossy compression it is hard
+to see any difference, so it's not worth it.
+@section Rendered files
+Once you start it, XaoS will generate thousands of frames. They take quite
+a long time to calculate and save, and consume plenty of disk space.
+(e.g. to render part 1 of the tutorial you need about 60MB and half an hour of time).
+
+All images are named @code{[basename]framenum.png}. For example @code{intro0001.png} is
+the first frame of the animation intro. If consecutive frames are the same, XaoS
+doesn't save them, so some frames may be missing. If your encoder can't handle
+that, you will need to write a simple script which will fill in the gaps by means
+of @code{mv} or symbolic linking.
+
+A list of all filenames is saved into the file @code{[basename].par}, where each line is
+the name of one frame. The names repeat here if necessary, so you can use this
+file to supply filenames to the encoder.
+@section Encoding videos
+Once XaoS has generated the png files for each frame of the animation, you
+can use a third-party video encoder to convert the sequence of images into
+a video file. We currently recommend the following encoders, which support
+a wide variety of video codecs and file formats:
+@table @strong
+@item ffmpeg
+Available from: @code{http://ffmpeg.mplayerhq.hu/}
+Instructions: @code{http://ffmpeg.mplayerhq.hu/faq.html#SEC12}
+@item mencoder
+Part of mplayer, available from: http://www.mplayerhq.hu/
+Instructions: @code{http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html}
+@end table
+These are both command line tools. If you prefer a graphical tool, you may
+prefer Quicktime Pro from Apple (http://www.apple.com/quicktime/pro/). However,
+this software costs approximately US$30, and the authors of XaoS have no
+experience with it. Although QuickTime may be easier to use, the two free
+encoders above are just as capable once you learn how to use them.
+
+
+Note: we used to recommend Berkeley parallel MPEG encoder to
+encode the generated png files into MPEG videos. We have kept
+the instructions mainly for historic purposes.

+@chapter XaoS's file format
+This section describes the format used by XaoS for animations, configuration
+files and saved positions. All these files have a common format, designed
+to be easily readable, to allow manual editing of files and easy conversion by
+other programs.
+
+I also taken care to make it easily extensible for future versions of XaoS
+so I hope there will not be many incompatibilities between various XaoS
+versions.
+
+The format is a simple set of commands executed sequentially. XaoS does not provide
+any variables/cycles as usual scripting languages do, but future extension to
+full-blown Scheme should be easy since the format uses Scheme-like syntax.
+The syntax of every command is:
+
+@code{(command_name }@emph{[param1] [param2]}@code{)}
+
+where parameters are optional and separated by whitespace (an arbitrary number
+of spaces, tabs and newlines). The parameters can have the following types:
+
+@table @strong
+@item integer
+number w/o decimal point (@code{123})
+@item float
+floating point number in decimal notation with optional exponent (@code{1.23E2})
+@item keyword
+text started by quote @code{'}. It is used to pass various string constants
+like formula name (@code{'mandel}) Quote is required for scheme compatibility
+@item string
+Text inside double quotes. The only parameter that should contain whitespace
+@item boolean
+@code{#t} for true or @code{#f} for false
+@end table
+
+There is a complete description of all XaoS functions (with some examples) and an
+index of functions in the XaoS registry. @xref{menus}. You may particularly want
+to read about the animation functions. @xref{animf}. Also, the following functions
+are significant:
+
+@table @strong
+@item load
+
+This function loads and interprets a file. It works similarly to @code{#include}
+in C.
+@item initstate
+
+Available in version 3.0 and above, this function resets XaoS's state to default
+values. This command should be at the beginning of each animation file,
+since otherwise some stuff previously enabled by user could cause unexpected
+effects. State is not reset by default before playing animations since it would
+make it impossible to write macros. Current versions don't really need macros, but
+in future versions, when the Scheme programming language will be available, this
+should be a much more interesting subject.
+@item usleep
+
+This function waits for a selected amount of time(in usec) before processing the
+next command. The screen is recalculated and displayed at the beginning of
+the sleep if necessary. The remaining time is spent by waiting, calculating if
+necessary, or performing any animation you entered via animation commands.
+@item wait
+
+Waits until the animation or image rendering is complete. Do not call this
+function when zoom, or continuous rotation is active otherwise deadlock happens. It is
+a good idea to call it immediately before text subtitles are displayed, since it looks
+ugly when they are displayed over a blocky unfinished fractal. Because the
+degree of blockiness at a given instant is a function of your machine speed,
+it may look nice for you but ugly for others with slower machines. Also
+you should call this after an animation is performed, before the switch to another
+fractal happens; since the switch involves calculation, the screen is stopped
+for a while and an unfinished fractal there looks ugly.
+You should also call it, when you want to do something as soon as possible.
+@end table
+
+Example:
+
+
+@example
+;configure everything for the first frame
+(inistate)
+(palette 1 1163254293 0) ;custom palette
+(cycling #t) ;enable cycling
+(cyclingspeed 7)
+(maxiter 276) ;higher number of iterations
+(range 3) ;default range for solid guessing
+(usleep 1000000) ;second frame starts here
+(moveview -1.8101154154614007889 -8.2687205907162041209E-05)
+;just move the image
+(usleep 1000000) ;third frame
+(morphview -1.8101154154614007889 -8.2687205907162041209E-05
+6.277210971069452361E-10 6.2772109785334669875E-10)
+;10 seconds of zooming into selected
+rectangle
+(usleep 100000000)
+@end example
+
+
+The best way to learn XaoS command language is probably to read position files
+and modify them. For example, to create zooming animation from the original
+file:
+
+
+@example
+(initstate)
+(defaultpalette 0)
+(formula 'mandel)
+(view -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+9.69332308834E-08)
+@end example
+
+
+Just change the @code{view} command to @code{morphview}, and add @code{usleep}:
+
+
+
+@example
+(initstate)
+(defaultpalette 0)
+(formula 'mandel)
+(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+9.69332308834E-08)
+(usleep 10000000)
+@end example
+
+
+The following code produces Julia morphing in the real axis:
+
+
+@example
+(initstate)
+(fastjulia #t)
+(juliaseed -2 0)
+(morphjulia 2 0)
+(usleep 2000000)
+@end example
+
+
+
+And following is the ``rotozooming'' animation:
+
+
+
+@example
+(initstate)
+(fastrotate #t)
+(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+9.69332308834E-08)
+(morphangle 300)
+(usleep 10000000)
+(wait)
+(fastrotate #f)
+@end example
+
+
+

+@section AA-lib driver
+
+The AA driver is currently the most advanced and portable driver for XaoS.
+It is based on AAlib---a high quality ASCII-art library developed by the AA-project.
+(see @code{http://aa-project.sf.net})
+
+It is a fully featured XaoS driver for text mode displays. It supports 256 colors
+and the mouse where possible.
+
+It also has some extended features available from the UI menu:
+
+@table @strong
+@item Attributes
+AA-lib may use character attributes to improve image quality.
+By default it uses normal, dim and bold characters where possible,
+but you can also enable different attributes like reversed or bold font
+characters. You may also enable usage of non ansii/reversed characters if
+your device supports it.
+@item Font
+AA-lib uses a bitmap image of the font to prepare the approximation table
+used for ASCII art rendering. This bitmap is expected to be same as the one used
+by your device. AAlib performs detection where possible however some devices
+(like UNIX text terminals or MDA) do not support this. AAlib has few font
+images compiled in, so in this case you should try to use one of them to
+achieve best results.
+@item Inversion
+Some devices use inverse video: use this to get correct results on such devices.
+@item Dithering mode
+Dithering is an way to get more exact color in approximations, by combining
+more characters; but this method can produce ugly looking noise on certain images.
+Use this menu to disable or tune it.
+@item Palette options
+By default AA driver uses the XaoS palette to render images, but it quite often
+looks ugly on text displays. Here you can choose a special text palette instead. Note that with
+filters enabled, the results may be rather ugly. This function is available from
+the @emph{palette menu}.
+@item Save text screen
+The normal save function will generate a PNG image instead of nice
+ASCII-art. To save ASCII art use this function instead. It supports many
+text file formats like HTML, ANSI, more, etc... It will also ask you for
+font and attributes(see above). It is available from the @emph{file
+menu}.
+@end table
+
+The AA-lib driver also provides the full set of standard AA-lib's command line
+options. You may use them to tune parameters like gamma correction, and so on.
+See @code{xaos -help} or the AA-lib documentation for details.
+
+The AA driver was written by Jan Hubicka, 1997.

+@section BeOS support
+
+XaoS has pretty advanced support for BeOS R4. It works on both PowerPC and
+Intel platforms, supports multithreading, the clipboard, file dragging,
+has native look and feel and can work as an image translator from XaoS files
+to images.
+
+The first version of the BeOS driver was written by Jens Kilian and later
+extended by Jan Hubicka.
+
+@subsection Installation
+
+You can start the installation script to do everything for you. If you want
+something special, read this section.
+
+In order for XaoS to work you need to keep the executable together with
+its data files (@code{help}, @code{examples}, @code{catalogs} and the @code{tutorials} directory)
+
+When first started, XaoS registers two new mime types called
+@code{image/x-xaos-position} for XaoS Position Files and
+@code{video/x-xaos-animation} for XaoS Animation Files,
+registers icons for them and sets itself as default application.
+
+@subsection Available display drivers
+
+XaoS supports following drivers:
+
+@table @strong
+@item BeOS
+Standard windowed driver using application server
+@item DirectWindow
+Driver done using Game Kit's direct window class
+@item WindowScreen
+Fullscreen driver.
+@end table
+
+By default, XaoS starts in windowed mode and uses the application server for output.
+You could change the driver to DirectWindow to use direct access to video RAM.
+Note that this mode is slower in most cases, and not supported by some videocards.
+
+The BeOS driver by default chooses the most similar bitmap supported by XaoS
+to achieve best and fastest results.
+In the UI menu you can change this default choice to another one if you wish.
+Also you can ask the BeOS and DirectWindow to resize to fullscreen mode.
+
+XaoS also supports real fullscreen mode using the BWindowScreen API. To switch
+XaoS to this driver, use the UI menu. If you want to use this mode by default,
+use the @code{-driver WindowScreen} command line option.
+
+This driver differs a lot from windowed ones. It use direct access to the video
+card, allowing you to change video mode. Also, the 256 color mode
+can access the palette, so it is not dithered like the windowed mode.
+Because BeOS can't do GUI in fullscreen mode, XaoS uses its own toolkit.
+I hope you will feel confortable in it.
+
+@subsection XaoS as translator
+
+You should be able to open XaoS files in graphics applications
+such as ShowImage or ArtPaing. In Preferences you can find the DataTranslations
+program, that can be used to set the size, type and DPI of the resulting image.
+Also antialiasing can be enabled.
+
+Note that @emph{translation can take a while}. So be patient and
+wait for the result.
+
+If the translator doesn't work, ensure that you have a link to the XaoS executable
+in @code{/boot/beos/system/add-ons/Translators/}.

+This is a fully featured driver for DJGPP and allegro.
+It supports many VGA modes, VESA 1.0---3.0, VBE/AF, S3 and some other cards.
+
+The following problems may occur:
+
+@table @strong
+@item Some DPMI servers may cause problems
+Some DPMI servers like the one from Novell/Dr/Open DOS are buggy. Use clean DOS
+instead and XaoS will automatically start @code{cwsdpmi}.
+Under Open Dr DOS use @code{dpmi off} at command line to disable it.
+@item Higher resolutions don't work
+If your videocard has enough memory for the selected resolution,
+you most probably have an unsupported videocard.
+Please use a VESA BIOS extension on this videocard. (See the note about VESA
+at the end of this section.)
+@item XaoS needs a coprocessor
+I don't distribute a coprocessor library linked into XaoS because it is too slow for
+a real-time zoomer. Coprocessor emulation will not help, because xaos works in protected mode.
+@item XaoS needs mouse driver to be usable
+@item XaoS works slowly in higher resolution
+This could also be caused by Allegro's slow driver or your videocard's VESA BIOS.
+You could try some other VESA BIOS extension instead.
+Look at the @code{http://www.talula.demon.co.uk} for the FreeBE
+project or Scitech Display Doctor package.
+(See the note about VESA at the end of this section.)
+@end table
+@subsection VESA
+VESA is a standard for using higher resolutions in DOS. Many videocards have
+VESA support in the BIOS so you don't need any additional software, while others
+need support from a special program. Also some VESA BIOS implementations are
+buggy or suboptimal; there are 3 different versions, version 1.0 is many times
+slower than 2.0, which has support for protected mode and linear framebuffers.
+So if you have problems with higher resolutions, or some graphics modes are
+not available (like 320x200 truecolor), you might try some software package
+which emulates VESA.
+
+The most famous VESA emulating program is Scitech Display Doctor. It has support
+for many videocards and is quite reliable. It's disadvantage is that it is
+shareware and works for only 30 days. You might also look on
+@code{ftp.simtel.net}, where there are many VESA emulation packages such as
+@code{s3vbe} or the new FreeBe project at
+@code{http://www.talula.demon.co.uk}

+@section DirectX fullscreen driver
+This is da river for Windows 9x and NT. It is new since version 3.1 and
+because of some oddities of Windows API and kludges in DirectX
+it may be rather unstable. Please report all bugs. In case
+of problems you could use the DOS version of XaoS instead.
+
+This driver allows the Windows port of XaoS to run in full screen mode.
+The driver supports 256, 65536 and 16777216 color modes (24bpp and 32bpp)
+in all resolutions supported by DirectX.
+You can change graphics mode by pressing the @code{=} key
+(or by using the UI/Resize menu). If the selected mode is not supported,
+the driver will restore the previous setting.
+
+Use the @code{-mode WIDTHxHEIGHTxDEPTH} (like @code{-mode 640x480x16})
+command line option to change graphics mode.
+
+If you want to start XaoS in DirectX, use the @code{-driver dX-fullscreen}
+option.
+
+See the Win32 driver documentation for some more Windows
+releated information.

+libggi, a portable graphics library, and XaoS's GGI driver uses that.
+It is experimental, since the API of libggi is not stabilized yet.
+There are some problems with keyboard handling---the shift key doesn't work
+yet.
+
+Everything else might work well, but there are no guarantees. It is alpha quality
+software.
+
+GGI driver was written by Jan Hubicka, 1998.

+@section Plan9 driver
+
+Plan9 is a very nice small operating system by the authors of Unix at Bell Labs.
+It is very incompatible with other operating systems; even the C compiler and
+header files are different, but XaoS should work well there (even on the
+limited free demo installation without any POSIX compatibility stuff)
+
+There are a few limitations: the file selector and image saving don't work.
+You can save position files and then later render them on the other OS, or save
+screenshots.
+
+Plan9 terminals also don't provide any way to catch the arrow keys, so you
+can't use them. Use the mouse to navigate in the menus. Also, getting the screen
+resolution is impossible, so use @code{-pixelwidth} and @code{-pixelheight}
+instead of @code{-screenwidth} and @code{-screenheight}.
+
+By default XaoS changes the colormap. This will collide with other colorful
+programs like Mortha. You can disable this behavior using
+@code{-nopalette} switch, but this will slow down XaoS.
+
+Plan9 driver was written by Jan Hubicka, 1997.

+@section SVGAlib driver
+
+This is a driver for Linux SVGAlib. I really like this driver, because
+I much prefer full screen zooming instead of a small 320x320 window in X11.
+It was one of the first drivers for XaoS and is fully featured.
+The following problems can occur:
+
+@table @strong
+@item XaoS doesn't initialize graphics mode
+when started under users other than root SVGAlib requires root privileges
+to directly access the hardware. When you really want to start XaoS as a
+normal user, enable the suid bit (@code{chmod +s}) at XaoS executable.
+note that I take care to disable all security holes caused by this
+bit so I believe it is safe.
+@item Mouse doesn't work
+@item Screen is blank at higher resolutions
+Both this problems are probably caused by misconfiguration of
+SVGAlib. Please configure it in @code{etc/vga/libvga.cong} or
+@code{/usr/local/lib/libvga.conf}
+GPM can also cause problems. Try to kill it before starting XaoS.
+@item When I switch console I can't switch back
+This is another typical SVGAlib bug. Try to hold @code{F} key longer than @code{alt}.
+It helps on my computer. On older SVGAlib there was a famous ``enter bug'' that caused
+a crash after pressing enter. Try to update to a newer release.

+@section Win32 driver
+
+This is a driver for Windows 9x and NT. It is new since version 3.1 and
+because of some oddities of Windows API it may be rather unstable.
+Please report all bugs. In case of problems you could use the DOS version
+of XaoS instead.
+
+The driver should work in all bit depths, but 16 color mode is not natively
+supported by the XaoS engine. XaoS internally works in 32k colors and
+the result is converted to 16 colors by Windows. Because Windows
+conversion routines are slow and ugly, the result is slow and ugly.
+Please configure your display to another bit depth to ``solve''
+this problem.
+
+Use @code{-size WIDTHxHEIGHT} command line option to change the default
+window size.
+
+This driver also maps to native Windows look and feel. There is a small
+problem with combo boxes in dialogs. They are expected to give you a choice
+between a few strings. The keyboard controls (changing choice by arrow keys)
+work, but mouse selection is broken. If you know how to solve this bug,
+please let me know.
+
+XaoS is a UNIX application and has many command line options.
+Some features are not available from the GUI.
+Because Windows applications can't have normal output,
+most of the critical messages are displayed in message boxes, but
+some longer messages are omitted. The most significant omission is the help
+about command line options that you can find in @code{doc/cmdopts.txt}.
+
+One thing that might be confusing is that animation rendering mode doesn't
+display anything, but only renders images. Start the rendering,
+and a message box will inform you that XaoS is entering the calculation
+loop. Relax and wait for the message box signaling the end of the loop.
+
+Note that XaoS also supports the DirectX API.

+This was the first driver done for XaoS. It supports many visuals, shared
+colormaps and MitSHM extension.
+
+Bugs/limitations:
+
+@table @strong
+@item XaoS makes some X servers too busy
+Sometimes XaoS generates images faster than X can display them.
+In this case XaoS responds poorly to the mouse, and other applications slow
+down too. This happens especially often on old R4 servers. Use @code{-sync}
+to avoid this problem. Note that @code{-sync} does @code{not} make all
+communication with X asynchronous; it just adds one additional XSync call.
+So the slowdown is not as large as you might expect.
+@item Does not work on all visuals
+This driver supports only 8bpp pseudocolor/grayscales, 15,16,24 and 32bpp truecolor, 1bpp and 8bpp staticolor visuals.
+@item Palette rotating does not work for 8bpp pseudocolor w/o private palette

+
+@appendixsubsec Include file
+@defun load file 
+@end defun
+
+This function lets you include another file in your script. It works similarly
+to @code{#include} in C or @code{load} in Scheme.
+The file is searched for in the same directory as the current source file.
+
+@emph{Available as}: command

+@node linemenu,  animf,  plc,  menus
+
+
+
+@appendixsec Line drawing functions
+XaoS has support for drawing lines. These functions are available only in
+animations and could be used to show some parts of fractals or draw simple
+diagrams. See the tutorial ``Introduction to fractals''
+for examples of this feature.
+
+Lines can be drawn in @emph{screen} coordinates, where 0,0
+is the top left corner and 1,1 is bottom right, @emph{scaled}
+coordinates, which are similar, but scaled to keep 0,0---1,1 rectangular,
+or @emph{Fractal} coordinates, to draw a line at an exact position
+on the screen.
+
+The color of the line should be specified by the @code{color} command.
+You might draw an arbitrary number of lines and, later, morph them. Each line is
+identified by a unique numeric key; the current key can be set using @code{linekey}.
+Commands for changing lines operate on the line with the current key.
+(Lines drawn in sequence have consecutive numbers.)
+
+For example:
+
+
+@example
+(color 'red)
+(line 'scaled 0.3 0.5 0.7 0.5)
+(line 'scaled 0.3 0.5 0.7 0.5)
+(line 'scaled 0.3 0.5 0.3 0.5)
+(line 'scaled 0.7 0.5 0.7 0.5)
+(linekey 0)
+(morphline 'scaled 0.3 0.3 0.7 0.3)
+(morphline 'scaled 0.3 0.7 0.7 0.7)
+(morphline 'scaled 0.3 0.3 0.3 0.7)
+(morphline 'scaled 0.7 0.3 0.7 0.7)
+(usleep 1000000)
+@end example
+
+
+Creates line morphing to rectangle.
+
+
+
+
+@defun line keyword complex complex 
+@end defun
+
+Draw line between two points.
+@code{keyword} specifies type of coordinates and should be one of the
+following: @code{`fractal}, @code{`screen} or @code{`scaled}.
+This function also increases the line key.
+
+@emph{Available as}: command
+
+
+
+
+
+@defun morphline keyword complex complex 
+@end defun
+
+Morph current line to given coordinates.
+@code{keyword} specifies type of coordinates and should be one of the
+following: @code{`fractal}, @code{`screen} or @code{`scaled}.
+The line will start moving at the next timing command, and reach the
+final position before the end of it.
+This function also increases the line key.
+
+@emph{Available as}: command
+
+
+
+
+
+@defun morphlastline keyword complex complex 
+@end defun
+
+This function has the same functionality as morphline, but it doesn't
+increase the line key, and touches the line with the previous key. This is useful when
+you want to move a just-drawn line---you don't need to set linekey back.
+

+@appendixsec Animation functions
+These functions are used to animate fractal state---to zoom, unzoom and morph
+various parameters. They should be used only in animation files.
+Animations are usually performed for a time selected by an immediately following
+timing function. @xref{time}.
+For example:
+
+
+@example
+(view 0 0 1 1)
+(morphview 0 0 2 2)
+(usleep 5000000)
+@end example
+
+
+Will do a 5 second long unzooming animation.

+@end menu 
+@node animateview,  smoothmorph,  ,  animf
+
+
+@appendixsubsec Animate view
+@defun animateview float float float float 
+@end defun
+
+This function is almost identical to function @code{view}. @xref{uiview}.
+It expects that the view will be changed only slightly, so recalculation is done
+with @code{ANIMATE} priority. This means that dynamic resolution is used by
+default.
+
+Viewport is selected by the center and two radiuses (real and imaginary). See
+@code{view} for more information.
+
+@emph{Available as}: command
+
+@node smoothmorph,  morphview,  animateview,  animf
+
+
+@appendixsubsec Smooth Morphing
+@defun morphview keystring starttime endtime 
+@end defun
+This function lets you smoothly start and stop morphing. Specify
+starttime and stoptime as nonzero, and morphing will speed up and slow down for
+that number of usecs.
+
+The keystring is used to select what morphing you want to control. It is one of
+the following:
+@table @strong
+@item 'view
+control morphview
+@item 'angle
+control morphangle
+@item 'julia
+control morphjulia
+@item 'line
+control morphline
+@end table
+@node morphview,  morphjulia,  smoothmorph,  animf
+
+
+@appendixsubsec Morph view
+@defun morphview float float float float 
+@end defun
+For the time selected by the next @code{usleep} or other timing function, the viewpoint is smoothly morphed from
+the current one to that selected by @code{morphview}.
+
+Viewport is selected by the center and two radiuses (real and imaginary). See
+@code{view} for more information.
+
+This function can easily be used for creating zooming/unzooming animations using position files.
+This is an example position file generated by XaoS:
+
+
+@example
+(initstate)
+(defaultpalette 0)
+(formula 'mandel)
+(view -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+9.69332308834E-08)
+@end example
+
+
+By replacing the @code{view} command with @code{morphview} and
+adding @code{usleep} you can create a zooming animation:
+
+
+@example
+(initstate)
+(defaultpalette 0)
+(formula 'mandel)
+(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08

+@emph{Available as}: command
+
+@node morphjulia,  moveview,  morphview,  animf
+
+
+@appendixsubsec Morph Julia
+@defun morphjulia complex 
+@end defun
+For the time selected by the next @code{usleep} or other timing function, the Julia seed
+is smoothly interpolated from the current one to that selected by @code{morphjulia}. By default this will
+cause recalculation of the whole screen.
+To avoid this, use fast Julia mode. @xref{fastjulia}.
+
+A simple animation morphing Julia seed in the X axis:
+
+
+@example
+(initstate)
+(fastjulia #t)
+(juliaseed -2 0)
+(morphjulia 2 0)
+(usleep 2000000)
+@end example
+
+
+
+@emph{Available as}: command

+@appendixsubsec Move view
+@defun moveview complex 
+@end defun
+Smoothly move the image center to another position.
+
+@emph{Available as}: command
+
+@node morphangle,  zoom,  moveview,  animf
+
+
+@appendixsubsec Morph angle
+@defun morphangle float 
+@end defun
+Smoothly rotate the image to another angle. By default rotation causes
+recalculation of the whole screen. To avoid this you need to enable
+fast rotate mode. @xref{rotate}. Don't forget to disable it later, since
+it slows down other animations.
+
+
+A simple ``rotozooming'' animation:
+
+
+@example
+(initstate)
+(fastrotate #t)
+(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08
+9.69332308834E-08)

+(fastrotate #f)
+@end example
+
+
+@emph{Available as}: command
+
+@node zoom,  ,  morphangle,  animf
+
+
+@appendixsubsec Zooming functions
+
+The functions for zooming/unzooming were created mainly for recording
+animations. In manually created animation files, it is easier to use
+@code{morphview}. @xref{morphview}.
+
+@defun zoomcenter complex 
+@end defun
+This function sets the center to zoom in on. The center is given as a position
+in fractal coordinates.
+
+@emph{Available as}: command
+@defun zoom 
+@end defun
+Start zooming to the area specified by @code{zoomcenter}.
+
+The speed of zooming should be controlled by the function @code{speed}
+or in a more exact way by @code{maxstep} and @code{speedup}.
+
+@defun unzoom 
+@end defun
+
+Start unzooming from the area specified by @code{zoomcenter}.
+
+@emph{Available as}: command
+@defun stop

+@appendixsec Timing functions
+Timing functions are used to control the animation replay daemon. It can wait

+are controlled by such waiting; animations that are running while delays start
+keep running through the delay.

+@defun usleep integer 
+@end defun
+
+This function waits for a given amount of time (in usec) before processing

+usleep if necessary necessary. The remaining time is spent in waiting or
+performing animation.

+
+@appendixsubsec Wait for text
+@defun textsleep 
+@end defun
+
+
+This function's behavior is very similar to @code{usleep},
+but the time is calculated from the number of letters currently displayed
+onscreen. If you want to wait just long enough for the user to read the subtitle,
+use this function. The user can alter the replay speed as desired using
+@code{letterspersec}. @xref{letterspersec}. This value can be changed during

+
+@emph{Available as}: command
+
+@node wait,  ,  textsleep,  time

+
+@appendixsubsec Wait for complete image
+@defun wait 
+@end defun
+
+Wait until the image is complete. You should always use this function after
+zooming or unzooming when dynamic resolution is in use. This ensures that
+the image calculation will be complete so the user can see the result before
+the animation continues. It may also be useful in combination with filters like
+motion blur. @xref{blur}.

+@appendixsubsec Mandelbrot/Julia mode
+
+Most fractals rendered by XaoS can be represented as Mandelbrot sets or Julias.
+Each point in the Mandelbrot set has its own Julia set. To learn more about
+this correspondence, see the tutorial on the Julia set.
+
+This function switches between Mandelbrot and Julia representations. When
+switching to Julia, you need to set the seed---a point selected from the
+Mandelbrot set.
+
+If you run this function from the menu, you are prompted for the Julia seed
+as a number. Often, this can be clumsy, and it would be easier to specify a
+point with the mouse pointer. If you hit the @code{M} key instead of
+using the menu, the current mouse position is used.
+
+Good seedpoints lie at the boundaries of the Mandelbrot set; other seeds
+usually generate quite a boring fractal. You can also explore various seeds
+at high speed using the Fast Julia mode. @xref{fastjulia}.
+
+Not all fractals have Julias, but XaoS can generate fake Julia sets for
+those that do not, which use some Julia-like modification of the formula;
+so this function is currently usable for all fractal types.

+@appendixsubsec Perturbation
+
+Perturbation is a simple trick which changes the point at which orbits start.
+Traditionally zero is used, but other values can generate interesting
+results too.
+
+On enabling this function from the menu, you will be asked for a complex
+number specifying the perturbation. It is a toggle; selecting it again
+resets the perturbation to zero without prompting.
+
+It can be used to specify a complex number representing a point on the screen.
+If you hit the @code{B} key instead of using the menu, the current mouse
+position is used. This too is a toggle, so @code{B} again will disable
+perturbation by setting it to zero.
+
+This function only has an effect for certain formulae (like the
+Mandelbrot set</a>) and only then in <a uimandelbrot>Mandelbrot mode. @xref{mandel}.
+
+@emph{Available as}: menu item
+@defun perturbation complex 
+@end defun
+
+This is the scripting-language variation of the perturbation function. Instead
+of toggling, you always specify the perturbation to use. Use 0 0 to disable
+perturbation.

+
+
+@appendixsubsec Bailout
+
+Bailout is the value which is checked for each point of
+the orbit if the point is far enough
+from the complex zero point in the current iteration.
+If the point is far enough, then the iteration immediately
+stops and the starting point on the screen will be
+painted with a given colour, depending on the fractal
+type and many other settings.
+
+For the Mandelbrot set
+this value is 4. Other fractal types usually
+have the same bailout value. For most fractals many bailout values
+give more or less similar output. E.g., for the second order
+Mandelbrot set one can prove that the sequence |z| (z:=z^2+c) tends to
+infinity if and only if |z|>2 for some element z of this sequence.
+In XaoS program, Bailout value is the square of this 2, i.e. you can change this
+to any value greater than 2 for similar results.
+
+Other fractal types may use other bailout values. The default
+is 4 for each types.

+@appendixsubsec View
+
+Set your current viewpoint in the fractal. This function is useful when you have
+found some interesting coordinates somewhere (on a web page, perhaps) and you
+want to see that position in XaoS.
+
+In the dialog you will be asked for the @emph{center}, @emph{radius}
+and @emph{angle} of the image.
+
+The center specifies the point which is displayed at the center of the screen.
+The radius is the radius of a circle around this point; XaoS will size the image
+so that this circle only just fits on the screen. The angle gives the rotation of
+the image in degrees.
+
+People specify fractal coordinates in many ways. Some people use the coordinates
+of the upper-left and lower-right visible points, specifying the coordinates as four
+numbers @math{x1}, @math{y1}, @math{x2}, @math{y2}.
+To set the same viewpoint in XaoS, set the real portion of the center to
+@math{(x1+x2)/2}, the imaginary part of center to @math{(y1+y2)/2}, and
+the radius to the greater of @math{x2-x1} and @math{y2-y1}.
+
+Other programs use a zoom factor instead of a radius. For these, you can set the
+radius to @math{2/zoom}.

+
+This function is used to set the visible area of fractal in animation files.
+It doesn't let let you specify the angle, (for that, see the separate function
+@code{angle}), but lets you specify an ellipse instead of a circle. You can
+specify both a real and an imaginary radius, so you have better control over the
+area that will be visible. XaoS will size the image so that the ellipse only just
+fits on the screen.
+
+@emph{Available as}: command line option, command

+
+Outcoloring modes are similar to incoloring modes, but indicate
+how to display the areas outside the set instead. As with incoloring modes, the
+value of the latest orbit can be used to determine the color of each pixel, but the
+default is to use the number of iterations needed for the value at that point to become
+recognisably divergent as the color.
+
+The tutorial on outcoloring has more information and
+examples.
+
+The cryptic names of the modes are mathematical formulae, where @emph{iter}
+means the number of iterations required for the value to become recognisably divergent,
+@emph{real} means the real part of the latest orbit, and @emph{imag}
+means the imaginary part. @emph{binary decomposition} uses a different color
+when the imaginary part of the orbit is lower than zero, and @emph{smooth}

+
+Truecolor coloring modes are similar to incolor and

+they directly calculate the red, green and blue components of the color.
+This lets you display more parameters at once, and produces interesting
+and often attractive results. On 8bpp displays you need to enable the
+palette emulator filter first to see anything, amd the quality
+won't be so good, as far fewer colors are available per parameter.
+
+The tutorial on truecolor coloring modes has more

+The cryptic names of the modes are always three mathematical formulae (one for

+@end defun
+
+XaoS has a solid guessing optimization: if all corners of a rectangle have
+the same color, it assumes that the whole rectangle is a solid colored block,
+and doesn't calculate points inside the rectangle. This optimization saves
+lots of calculation, but sometimes introduces errors. This value alters the
+maximum size of the rectangle that can be guessed at one time. The default
+value is 3; use 0 to disable the optimization.

+
+
+@appendixsubsec Periodicity checking
+@defun periodicity bool 
+@end defun
+
+Periodicity checking is one way to speed up the calculation. Areas inside the
+set always need @code{maxiter} iterations to determine that
+the point is probably inside the set (while it is rare for areas outside to
+need anywhere near that much). Often the orbital trajectory falls into a
+periodic, repeating cycle; if that can be detected, the calculation can be
+stopped early, as there's no way that the orbit can ever leave the cycle
+again (hence it cannot diverge, hence the point must be inside the set).
+
+Implementating this method efficiently is quite problematic. It slows down
+the cases where cycles are not found, because cycle-checking is quite hard work
+and has to take place for all points, even those that don't become cyclic.
+Because of the inexactness of floating-point calculations, the cycles are
+never exact, so you need to use an error value. Higher error values mean that
+cycles will be detected sooner, while lower error values increase the
+exactness of the calculation. Higher values can introduce serious errors,
+especially at the front of the Mandelbrot set. XaoS detects this automatically
+and corrects for it in most cases, but sometimes it might be wrong. Also,
+other optimizations in XaoS (such as boundary tracing) don't give this method
+much of a chance to run, since areas inside the set are usually not
+calculated at all.
+
+That's why the advantages of this optimization are questionable. You should
+probably experiment with enabling and disabling it. Sometimes XaoS is faster
+with this enabled, sometimes when disabled. Also, this method works only
+when incoloring methods are disabled, and only for some
+fractal types (some fractal types, e.g. newton, don't have any concept of
+an area `inside the set' at all.)
+

+
+When the fractal set is calculated, a orbital trajectory is examined for each
+point. If the orbit diverges to infinity, the point is outside the set.
+Otherwise, the point is inside the set. For exact calculations, you need to
+know the entire orbital trajectory, which is infinitely long for areas inside
+the set, so fractals cannot be calculated exactly. By default, XaoS calculates
+at most 170 positions (iterations) and then gives up; if the point is still
+inside the bail-out value, it guesses that the point is inside the set.
+
+When zoomed into a detailed area, especially one close to the set boundary,
+this value could become too low, and the fractal will become boring.
+You might try increasing this value if you want to get the image interesting
+again; but this necessarily slows down the calculation at the same time.

+
+Fractal images are good as a base for random dot stereograms. In
+case you don't know what these are, please point your browser to
+Google or another search engine and find some articles about such
+images, because learning to read such images takes some effort. They
+make it possible to generate three dimensional images on a normal monitor
+without any additional hardware, by exploiting bugs in the human brain
+(although you need two working eyes, and some people never learn to
+see them; they can simply ignore this feature).
+
+XaoS is able to generate these images in animations, so you may use
+all normal XaoS functions (except palette changing and palette rotation,
+which makes no sense applied to a stereogram). To make the animation yet
+more exciting, XaoS emulates ``falling'' into the set; while you zoom in,
+your distance from the set drops and drops---but you never hit it; when the
+set reaches the level of your monitor, the distance is changed again so
+you are far away.
+
+To make this work right, XaoS needs to know the @emph{exact size of your
+monitor}. Because most platforms have no way to determine this, you need to
+use @emph{command line options} to tune it. If it's not set or is wrong,
+the stereograms will probably be impossible to see (if your monitor is too
+big or resolution too low), or the images will seem to be shallow (if your
+monitor is too small or resolution too high).
+
+By default XaoS expects my 15" monitor (29.0cm x 21.5 cm). Another
+cause of problems is the virtual screen supported by some windowed
+environments (like some X servers) that makes a program think that the
+resolution is higher than it actually is, and you see only part of
+this extra-large screen.
+
+The worst thing you could possibly do is to run full-screen XaoS in some
+graphical windowing system (OS/2 on top of Windows or Wine on top of Linux,
+perhaps) where XaoS can't tell the real size of its window at all. In such
+cases, it's normally better (not to mention faster) to run XaoS natively,
+rather than under such an emulation layer.

+Lets you specify the size of your screen in centimeters. Note that
+you need to specify the size of the visible image on the monitor, not
+the size with edge borders, or the size of the tube. The simplistic
+`my monitor is 17", just turn 17" into centimeters' doesn't work;
+that 17" is a marketing figure and has only a vague connection to
+reality. Get out a ruler and measure it.
+
+@item @code{-pixelwidth}, @code{-pixelheight}
+Lets you specify the exact size of a single pixel, if XaoS cannot
+determine this for itself from your screen size.
+@end table
+
+These options are used by some other parts of XaoS as well, so you should
+use them even when you don't want to see stereograms. You should probably
+write a small starting script (or alias, or shortcut; whatever your environment
+uses) that passes the correct parameters to XaoS.
+
+If the window is @emph{smaller than 8cm in any direction}, you will probably be
+unable to see anything; make the window bigger.
+
+The correct way to see XaoS stereograms is:
+@table @strong
+@item 1
+Start XaoS with options specifying the exact size of your screen or one pixel on it
+@item 2
+Sit 60cm away from monitor
+@item 3
+If you use a windowed environment, resize XaoS's window to make it wider than, say, 15 cm.
+@item 4
+Enable the filter (by pressing @code{E})
+@item 5
+focus on a point far away from the monitor (try to use your
+own reflection, if your monitor's not antireflective); the random blurring should
+eventually fall into the pattern of a Mandelbrot set.
+@item 6
+Carefully use your mouse to zoom into interesting areas
+(it is easy to lose concentration when you are not trained; but you can use
+the autopilot...)
+@item 7
+Enjoy animation :)
+@end table
+
+If you still can't see the stereograms, it could be that the fractal, or your eye,
+is deformed. A deformed fractal can be caused by your specifying your monitor size
+wrongly. Visual problems that damage depth perception, as well as problems like
+astigmatism, can make it impossible to see stereograms at all.

+
+@node interlace,  blur,  stereogram,  mfilter
+
+
+@appendixsubsec Interlace filter
+
+The interlace filter halves the horizontal resolution, and in each frame alternates
+between drawing only the even and only the odd lines. This speeds up the
+calculation, and in higher resolutions produces a motion-blur-like effect.
+
+@emph{Available as}: menu item, command line option
+
+@node blur,  emboss,  interlace,  mfilter
+
+
+@appendixsubsec Motion blur
+
+Motion blur mixes the current frame with previous ones to produce a
+motion-blur effect. It might be rather slow in 16bpp truecolor modes. The best
+results can probably be seen in 8bpp modes, so you might want to enable the
+palette filter first.
+
+@emph{Available as}: menu item, command line option
+
+@node emboss,  palettef,  blur,  mfilter
+
+
+@appendixsubsec Emboss
+
+This is a standard emboss filter, as seen in programs such as the GIMP or
+Photoshop. It produces especially nice results with the smooth
+outcoloring mode. @xref{outcoloring}.
+
+@emph{Available as}: menu item, command line option
+
+@node palettef,  anti,  emboss,  mfilter
+
+
+@appendixsubsec Palette emulator
+
+XaoS can work in either palette or truecolor mode. Both modes
+have advantages and disadvantages. Palette mode allows effects such as palette
+rotation, while truecolor mode allows smoother incoloring
+and outcoloring modes and the
+truecolor coloring modes. If your display is truecolor, you
+can enable this filter to get palette emulation (albeit not as cheaply as in
+a real paletted mode).
+
+@emph{Available as}: menu item, command line option
+
+@node anti,  truecolor,  palettef,  mfilter
+
+
+@appendixsubsec Antialiasing
+
+Antialiasing is a technique to increase image quality by eliminating jagged
+edges. XaoS calculates four values for each pixel (on the subpixel boundaries)
+and uses the average of them for the pixel value.
+
+This filter slows XaoS down a @emph{lot} and greatly increases memory
+requirements. It is useful mainly when you want to save images and want to make
+them look as nice as possible. Antialiasing also helps a lot when you want to
+encode JPEG or MPEG files; they are much shorter if antialiased (MPEG and JPEG
+hate jagged edges).
+
+@emph{Available as}: menu item, command line option
+
+@node truecolor,  ,  anti,  mfilter
+
+
+@appendixsubsec Truecolor emulator
+
+XaoS can work in either palette or truecolor mode. Both modes
+have advantages and disadvantages. Palette mode allows effects such as palette
+rotation, while truecolor mode allows smoother incoloring
+and outcoloring modes and the
+truecolor coloring modes. If your display is 8bpp, you can enable
+this filter to get truecolor emulation (but, obviously, not with as many colors
+as a real truecolor display).

+
+@emph{Available as}: menu item, command line option, command
+
+In the scripting language you can use the following functions for better
+control:
+@defun maxstep float 
+@end defun
+
+Selects the zooming/unzooming speed. The parameter specifies how much of the
+range will be removed each twentieth of a second; 0 means nothing, 1 means
+everything (the parameter obviously has to be less than 1).
+Higher values mean faster zooming.
+
+@emph{Available as}: command
+@defun speedup float 
+@end defun
+When zooming/unzooming, every twentieth of a second the @code{speedup}
+value is added to the current step until @code{maxstep} is reached.
+So this value selects the rate at which zooming stops and starts.
+Both these functions are more for internal use of XaoS then for manually
+written scripts, but they could come in useful nonetheless.

+press @code{A}, play your favorite music, drink coffee and relax. I never
+tried this but it should be really relaxing! Many pictures in the XaoS
+gallery were discovered using the autopilot.
+
+The autopilot also has some additional features. It backtracks if the
+zoomed picture is not interesting anymore, and can detect when it's zoomed
+into really a boring part of the fractal or reached the limit of floating
+point arithmetic on the platform, and restart zooming from the top.

+Default palette
+@item 1
+Black to color gradient
+@item 2
+Black to color to white gradient
+@item 3
+Cubistic-like algorithm.

+@appendixsubsec Color cycling
+@defun cycling bool 
+@end defun
+
+Color cycling is an old and simple effect to animate fractals. The Mandelbrot
+set looks particularly nice when color-cycled. On truecolor displays, color
+cycling fails to initialize (since those displays don't have a palette).
+You can enable palette emulation filter to make it possible.
+
+@emph{Available as}: menu item, command line option, command
+
+In the user interface, colors can also be cycled in the opposite direction
+with the ``@emph{Reversed color cycling}'' function.

+
+@appendixsubsec Shift palette
+@defun shiftpalette integer

+
+Shift palette by the specified number of cells. This can be used to tune the
+palette's position on the fractal. You can also use the
+@emph{Shift one forward} and @emph{Shift one backward} functions
+for fine-tuning. Note that shifted and rotated palettes could look different on
+different displays (because they may have different palette sizes).
+
+Shifting the palette on truecolor displays causes a recalculation of the screen.
+To avoid this, you could use palette emulation filter. @xref{palettef}.

+
+Overview of the XaoS design
+***************************
+
+   Whole sources of XaoS are designed into several "libraries" (some of
+them are not really libraries, but added into other's, but should be
+separated easily).
+
+   Understanding to the main philosophy should help you to navigate in
+the sources.  I also expect that many of the lower level stuff should
+be useful in the other projects, since it is designed to be fairly
+generic.
+
+   So here is an overview from the lowest level stuff to the highest.
+
+Palette and image library
+=========================
+
+   Sources are in directory `src/filter'. The aim of palette library is
+to provide relatively abstract interface to the various visuals and
+hide differences in the hardware and driver implementation. Fixedcolor,
+pseudocolor, grayscale and truecolor visuals should be handled in the
+almost same way.
+
+   It provides the structure `palette', which contains actual palette.
+You might allocate new colors here (you give RGB value and
+corresponding pixel is returned), interpolate colors where possible,
+cycle colors and so on.  Every palette also consist from the two
+parts--the preallocated color cells and the actual palette. This lets
+for example to GUI possibility to allocate statically colors for its
+texts and dialogs, while rest of palette is under control of different
+parts of XaoS.
+
+   This library also contain set of functions to allocate different
+palettes used by other parts. I expected that different parts of XaoS
+should use same palette. Nothing similar happened yet, but functions
+are kept here.
+
+   The image library is built at the top of palette library. It extends
+functionality for handling actual image data. Each image is represented
+by one or two frame-buffers (it is useful for double-buffering). One
+frame-buffer is called current and other old. They should be flipped by
+special function.  Program can draw into both of them.
+
+   Frame-buffers are hold as the set of pointers to the scan-lines.
+This brings better flexibility, because tricks like sub-windows, or
+flipped bitmaps are possible. Also speeds up, since you should avoid
+one multiplication.
+
+   The last significant information image structure hold is of course
+bpp depth.  It is counted in bytes, and should be 0-4. Where 0 is used
+for 1bit bitmaps.
+
+Filter library
+==============
+
+   Source are available in `src/filter'. This library controls the
+process of creation of the image. It handles an queue of the filters,
+where each filter should modify the image. There are two special filter
+at the beginning and end of queue. The first filter is usually the
+actual fractal engine which creates image, while the terminal filter is
+usually user interface helper library.
+
+Xthread library
+===============
+
+   This library provides interface to various multi-threading libraries
+(currently the BeOS, plan9 and POSIX implementations are available). It
+allows to run various function paraelly and some synchronization
+primitives (semaphores). It is simple, but has all the functionality
+required for the XaoS engine.
+
+Fractal library
+===============
+
+   Source are available in `src/engine/', headers in `fractal.h'.  This
+library contains the actual fractal calculation routines. It operates
+with fractal context, which contains informations like current formula,
+seed for julia, palette etc.
+
+   Functions for calculating the various fractal types and various
+coloring modes are available here.
+
+Zooming engine and other filters.
+=================================
+
+   Source are available in `src/engine/'.  This is the actual zooming
+engine filter. It is done in fairly independent way at fractal library,
+so it should be possibly used for zooming other stuff.  (it was already
+used for zooming large scale images containing maps of Hungary).
+
+   All other filter has their special file, where is implementation and
+structure containing all functions exported from the filter to user
+interface. They are registered in the file `ui_helper'.  One other
+terminal filter is implemented--Julia morpher. Other filters adds
+special effects (such as motion blur), or does conversions (such as
+rotation, dithering etc.)
+
+Timer library
+=============
+
+   This library provides many of very useful timing primitives. Such as
+timers, etc. Currently it is used by some other programs too.
+
+xio library
+===========
+
+   This library aims to provide united interface to file-system. Some
+strange systems (such as MacOS) has file-system API done in much
+different way than in UNIX. They don't have names in string, and uses
+special structures etc.
+
+xshl library
+============
+
+   Xshl stands for XaoS simple hypertext library. It contains fairly
+universal engine parsing an xshl language. It is similar to HTML with
+some additions and many restrictions. It should render this texts for
+the proportional/non-proportional fonts and various sizes.
+
+help library
+============
+
+   it is built at the top of xshl and xio libraries. It should read
+help files, wick contains an chapters. Parse chapter with given keyword
+etc.
+
+xmenu library
+=============
+
+   This is the XaoS function registry. All functions from UI-Helper
+library are registered in the registry. From this registry the menus,
+dialogs, command line options and scripting language are built.
+
+Catalog library
+===============
+
+   This is library for handling an message catalogs. It should read
+catalog and convert the keyword into actual message.
+
+PNG library
+===========
+
+   This library provides the function for saving an image from Image
+library to the file (in PNG format). Other formats should be added as
+well if required.
+
+UI-helper library
+=================
+
+   This library controls all the low-level stuff and provides an high
+level interface to it. It has functions for playing animations,
+zooming/UN-zooming and such. It heavily uses all the described
+libraries. It don't implement functions for handling menus and such,
+but makes great help for such implementations, because of the function
+registry database.
+
+Ugly interface
+==============
+
+   This is currently the only real user interface for XaoS (there is
+also an second, wich is used for rendering animations, but it is not
+user interface, how users expect it). It is built at the top of
+UI-helper library and provides functions for drawing menus, dialogs and
+such.  It has drivers for many platforms, and it should be easily
+ported to the others.
+
+   In the future, it should be quite easily to extended to let drivers
+specify their own menu/dialog handling code, so it should be possible
+to give it an "native" look of given platform.
+
+   It has also an function, where an GUI drawing routines are disabled.
+Function registry database is transfered trough pipe to external
+program, wick should build the menus and act as external user
+interface. It then back sends an commands in the scripting language
+representing things, that user done.  So it is an another way, how to
+give native look to ugly interface.
+
+   Ugly interface has also one serious limitation--for the historical
+reasons it is coded to handle just one window (rest of XaoS probably
+can do multiple windows--untested). So in windowed environments it is
+impossible to open multiple menus with fractals. At the other hand,
+this limitation is not so important, once external GUI enter the role.
+They should just start multiple XaoS engines. This will bring extra
+robustness, multitasking and some other advantages, so it is the
+proffered way. Thats why I don't plan to remove this limitation yet.

+
+Driver API description
+**********************
+
+   To port successfully XaoS to some platform you need:
+
+   * ANSI C compatible optimizing compiler. Note that optimizing
+     compiler is really required, since XaoS is coded to be good target
+     for optimizations and don't have any routines coded in assembly,
+     so if you will use some bad compiler, you should receive more than
+     ten times slower result. Also note that some compilers has serious
+     problems with compiling XaoS--like most of DOS compilers (Watcom
+     C, Borland C, Microsoft C etc...), has serious problems.  They
+     generate incorrect code or crash during compilation. I highly
+     recommend to use GNU C compiler. Even some versions of GNU C has
+     problems. Please read `compilers.txt' for more information.
+
+   * Fast way to avoid division by zero/overflow and other floating
+     point exception. XaoS is carefully coded to not to crash in this
+     case, but don't have any tests to avoid such situation and expect
+     random result in such case.  Many platforms provide way to switch
+     coprocessor into mode, where 1/0 is evaluated into Inf etc. If
+     there is no such way, try to use some kind of signal handler that
+     will ignore such exceptions.
+
+     The "normal" solution--add ifs to avoid division by zero is almost
+     impossible. The division is quite easy to check. But other
+     cases--overflows are much worse. So I don't think it is possible
+     to avoid all crashes just by adding ifs.
+
+     XaoS don't depend at IEEE arithmetic. Result in such cases should
+     me mostly undefined. XaoS usually works well with compiler's
+     switches for inexact math enabled (such as `-ffast-math' in GNU).
+     But no guarantees. For example at Alphas this is not true--since
+     they usually generates exceptions then.  Also `-mno-ieee-fp' at
+     Intel don't work. This is due to gcc bug. Gcc in some cases reverse
+     the condition when this switch is enabled. I've made patch to fix this
+     problem and hope that it will get to egcs or gcc soon.
+
+   * Text or graphics output device. If you have only text output
+     device, you may use AA driver, which renders fractals into high
+     quality ASCII art. In this case you might skip this chapter,
+     download AA-lib (http://www.ta.jcu.cz/aa) and read porting chapter
+     of AAlib manual. Graphics device must one of:
+
+        * 8bits per pixel with user definable palette `C256', static
+          palette `FIXEDCOLOR', or static grayscale `GRAYSCALE'
+
+        * 16bits per pixel with arbitrary bits per each color
+          `TRUECOLOR'
+
+        * 24bits per pixel with 8 bits per each color, arbitrary order
+          `TRUECOLOR24'
+
+        * 32bits per pixel with arbitrary order of colors, where each
+          colors fit to exactly one byte `TRUECOLOR'
+
+        * 1bits per pixel bitmap with both orders (Least or Most
+          significant bit first)
+
+     Please contact me if you have different kind of device. Some modes
+     (like miss-ordered truecolor modes) should be added really easily
+     if required.  Note that mono/4/16 colors devices will be probably
+     never supported internally by XaoS, since I expect they will be
+     slower than 8bpp, so XaoS will internally work in 8bpp and then
+     image should be converted. Contact me if you want to write such
+     converter. (For bitmap there already exists--see `dither.c'.
+
+   * Some way to save images. By default XaoS uses `pnglib', which is
+     ported to many platforms, but there is still many others. If your
+     system has some standard image format, which is easier to handle
+     than `.png', contact me and I will show you, how to add such
+     support to XaoS (see `png.c').
+
+   * Stdio compatible library (this is problem at Mac or BeOS). XaoS
+     has the abstract layer at the top of stdio, so it should use other
+     input/output libraries too. You might write just another
+     implementation if it's library called `xio'. See `xio.h'.
+
+   Ugly interface is designed to make writing of new drivers as easy as
+possible.  You need to write just few functions to fill following table:
+(use file `ui_template' for starting of writing new driver from scrath)
+     struct ui_driver {
+       char *name;
+       int (*init)(void);            /*initializing function. returns 0 if fail*/
+       void (*getsize)(int *,int *);	/*get current size..in full-screen versions
+                                       i.e svga and dos asks user for it*/
+       void (*processevents)(int,int *,int *,int *,int *);
+                                     /*processevents..calls ui_resize,ui_key
+                                       also returns positions of mouse..
+                                       waits for event if first parameter is
+                                       1*/
+       void (*getmouse)(int *,int *,int *);
+                                     /*returns current mouse positions*/
+       void (*uninit)();             /*called before exit*/
+       int (*set_color)(int,int,int,int);
+                                     /*alloc palette color and returns number*/
+       int (*set_range)(ui_palette *palette,int start,int end)
+                                     /*Set palette range*/
+       void (*print)(int,int,char *);/*prints text*/
+       void (*display)();            /*displays bitmap*/
+       int (*alloc_buffers)(char **buffer1,char **buffer2);/*makes buffers*/
+       void (*free_buffers)(char *buffer1,char *buffer2);/*frees buffers*/
+       void (*flip_buffers)(void);   /*prints text*/
+       void (*mousetype) (int type); /*Change mouse cursor*/
+       void (*flush) (void);         /*Flush current state to screen*/
+       int textwidth;                /*width of text*/
+       int textheight;		/*height of text*/
+       struct params *params;        /*command line parameters*/
+       int flags;
+       float width,height;
+       int maxwidth,maxheight;
+       int imagetype;
+       int palettestart,paletteend,maxentries;
+       int rmask, gmask, bmask;
+       struct gui_driver gui_driver;
+     };
+
+Functions
+=========
+
+   Ui uses following functions to communicate with driver:
+
+ - Function: init
+     function that initializes driver and returns 1 if success and 0 if
+     fail
+
+ - Function: getsize (INT *WIDTH, INT *HEIGHT)
+     returns size of screen(window) x and y
+
+ - Function: processevents (INT WAIT, INT *X,INT *Y, INT *BUTTONMASK,
+          INT &KEYS)
+     gets new keyboard/mouse events. parameters:
+    WAIT
+          if 1 function can wait for next event otherwise just lookup if
+                    something came. This is useful on multi-tasked os
+          where xaos 	   does not eats unnecesaru CPU.
+
+    *X,*Y
+          here returns current positions of mouse
+
+    *B
+          returns mask of `BUTTON1',`BUTTON2',`BUTTON3' for mouse
+          buttons
+
+    *K
+          returns mask for cursor keys
+         `1'
+               left
+
+         `2'
+               right
+
+         `4'
+               up
+
+         `8'
+               down             function also calls `ui_key' (ASCII
+     character) and ui_resize if required.      For special keys use
+     `UIKEY_UP', `UIKEY_DOWN', etc. See     `ui.h' for complete lists
+     of this constants.
+
+     note in case of problems freeing/allocating inside processevents
+     you may     call `ui_call_resize' that calls resize later outside
+     this function
+
+ - Function: uninit
+     Unitialises driver--called before exit.
+
+ - Function: set_range (UI_PALETTE *PALETTE, INT START, INT END)
+     This is an preffered way to set palette (second way is `set_color')
+     when `imagetype' is `UI_C256' (256 color with palette) one of this
+     two functions is required. In truecolor modes they are unused. In
+     case direct access to palette is possible at your platform, define
+     this one. Function is expected to set all color cells between
+     START to END to colors defined in PALETTE. `Ui_palette' is array
+     of UI_RGB. `Palette[0]' is color for entry number START. `Ui_rgb'
+     is an array of `char'.  `Palette[0][0]' is red field of entry
+     number START, `Palette[0][1]' is green and `Palette[0][2]' is
+     blue. `0' means black and `255' means full intensity. Use `NULL'
+     if your driver don't support this call.
+
+ - Function: set_color (INT R, INT G, INT B, INT INIT)
+     This is an secondary way, that should be used at platforms w/o
+     direct   palette access (like X11 or static color schemes). It
+     receives RGB value   of color, and returns index of color cell
+     with this color or -1 if no more   color cells available. An INIT
+     parameter is set to 1, when first entry   of palette is allocated,
+     `set_color' is expected to free all color   entries previously
+     allocated. Use `NULL' if your driver don't support   this call
+
+ - Function: print (INT `x',INT `y', CHAR *`text')
+     prints text to screen at position x/y. This function is a bit
+     archaistic   (XaoS now uses in the most cases its own functions
+     drawing directly to the   buffer), but in some
+     cases--initialization messages or calculation,   functions are
+     unusable, so we still need this primitive. In the `C256'   mode
+     you might rely, that first allocated color is always black and
+     second   is white.
+
+ - Function: display (VOID)
+     displays current buffer to screen
+
+ - Function: alloc_buffers (CHAR **BUFFER1,CHAR **BUFFER2)
+     allocs two buffers that can hold screen size bitmap.    Also sets
+     current buffer to BUFFER1. Since version 2.1 returns scan-line
+     size in bytes(usually width) and 0 if fail. This is useful on
+     systems, that   allocated bitmap bigger than
+     window/screen(dividable by 4 or so)
+
+ - Function: free_buffers (CHAR *BUFFER1, CHAR *BUFFER2)
+     frees allocated buffers
+
+ - Function: flip_buffer (VOID)
+     flips buffers--set current buffer to other one
+
+ - Function: flush (VOID)
+     This function should be used by drivers with buffered output to
+     flush   output buffers. Other driver should set it to NULL.
+
+ - Function: mousetype (INT TYPE)
+     This function is used to change mouse cursor. It receives
+     following values:
+    `NORMALMOUSE'
+          This mouse is usually displayed at screen, when UI waits for
+          user      commands
+
+    `WAITMOUSE'
+          This mouse is displayed when UI is busy(should be famous wait
+          clocks)      or you may use mouse defined in
+          ui_dos--mandelbrot set
+
+    `REPLAYMOUSE'
+          This mouse is displayed during replay. Should be none at
+          fullscreen      drivers, since blinking mouse cursor during
+          replay looks ugly. At      windowed system disabling mouse
+          looks ugly, so it should be some funny      cursor.
+     You should use NULL if your driver don't support this.
+
+Other information
+=================
+
+   Also some additional variables are used to inform ui about driver.
+All this values can be changed by init functions in case they are
+unknown before.
+
+TEXTHEIGHT, TEXTWIDTH
+     width and height of your font
+
+PALETTESTART, PALETTEEND
+     First and last palette entry, that should be changed. This you
+     should use   to avoid changing of entries reserved for window
+     system, text, mouse etc.
+
+RMASK, GMASK, BMASK
+     This fields are used in truecolor modes to specify, where each
+     color is   defined
+
+MAXENTRIES;
+     Number of allocatable entries. Normally should be
+     PALETTESTART-PALETTEEND
+
+IMAGETYPE
+     defines type of image. Should be one of following values:
+    `UI_C256'
+          classical 256 color with palette scheme used by most older
+          graphics     adapters. You should use it also for
+          static-color schemes but they are     not supported well in
+          current version.
+
+    `UI_TRUECOLOR'
+          32bpp truecolor mode
+
+    `UI_TRUECOLOR24'
+          24bpp truecolor mode.
+
+    `UI_TRUECOLOR16'
+          16bpp truecolor mode
+
+   FOLLOWING PART IS NOT REQUIRED TO MAKE FIRST VERSION OF DRIVER
+WORKING.  so you may skip to REGISTERING DRIVER for first read and
+return here later.
+
+PARAMS
+     Using this you may define command line options for you driver.
+
+     They are defined using params structure like:
+            static struct params params[]={
+              {"-mode",P_NUMBER,&defmode,
+                "Select graphics mode(same number as in interactive menu)"},
+              {NULL,0,NULL,NULL}  /*this is MUST be last option field*/
+            };
+
+     every line is one parameters. List ends with `{NULL,0,NULL,NULL}'.
+      First filed is option name.    Second field is type of parameter:
+    `P_SWITCH'
+          no parameter--variable is just set to 1 if option
+
+    `P_NUMBER'
+          integer number
+
+    `P_STRING'
+          string
+
+    `P_FLOAT'
+          floating point number (variable is float)     Third is
+     pointer to variable that is changed if option is set.    It is for
+     example `int*' for `P_NUMBER' or `P_SWITCH' and so on..    Last
+     one is help text. Displayed by `ui -h'
+
+WIDTH,HEIGHT
+     see FLAGS. May be set to `0.0, 0.0' for the beginning
+
+MAXWIDTH,MAXHEIGHT
+     see FLAGS. May be set to 0,0 for the beginning
+
+FLAGS
+     This variable says more about your driver. You may start with
+     value 0.    But for final version it is recommended to read
+     following chapter carefully.
+
+     Flags are uppercase constants and should be set by following way:
+
+     `ASYNC_PALETTE | RANDOM_PALETTE_SIZE'
+
+     following switches are supported:
+
+    `RANDOM_PALETTE_SIZE'
+          random size of palette. This is used in X where palette is
+          shared between     programs. By default xaos allocates all
+          available colors up to 256. This     is not very nice to
+          other applications in X. So randomsize causes that     just
+          some random number of colors(between 8-256) are allocated.
+
+          Also when this variable is off XaoS expects that allays same
+          number of     colors is available.
+
+    `UPDATE_AFTER_RESIZE'
+          recalculate and redraw screen even if its size is not changed.
+             In case that resize procedure destroys data in buffers
+
+    `RESIZE_COMMAND'
+          Some drivers (mainly the fullscreen ones) may in the function
+          `get_size'     ask user for the size and color depth. It
+          should be nice to let user change this parameter     at
+          runtime. I.E force XaoS to reinitialize his images. This is
+          done by     `ui_resize' call. This call in windowed drivers
+          is called by the     external event. But in fullscreen
+          drivers you need key/menu item for this.      You might add
+          this function directly into XaoS's function registry (see
+          for example the GGI driver)--it is usefull mainly when you
+          want to make     some size selection dialog in the standard
+          way, or let XaoS add his default     one. And this is done by
+          this flag. See for example SVGAlib or DOG driver.
+     Screen/window size informations:
+
+     Xaos needs to know exact size of displayed images. This is required
+        for random dot stereo-grams and also for keeping fractals in
+     their shape     (do not make them wide on 640x200 resolution etc.)
+        So minimally one of the following values should be defined.
+      (they are sorted in order I prefer them)
+    `SCREENSIZE'
+          values width/height specifies exact size of screen/window in
+          centimeters
+
+    `PIXELSIZE'
+          values width/height specifies exact size of one pixel in
+          centimeters      This is better for windowed environments
+          where window size is often changed
+
+    `FULLSCREEN'
+          driver runs fullscreen. XaoS automatically uses default
+          screen size      (29.0cm x 21.5cm)
+
+    `RESOLUTION'
+          driver does not know exact screen size. But knows resolution
+          used.       (it is in variables width/height) XaoS
+          automatically calculates      pixel width
+          using:29.0cm/maxwidth      and height: 21.5/maxheight
+     Of course default width and height can be changed by command line
+     options.     You may also use combinations like:
+
+    `SCREENSIZE | FULLSCREEN'
+          the best for fullscreen drivers
+
+    `PIXELSIZE | RESOLUTION'
+          the best for windowed drivers
+
+    `FULLSCREEN'
+          for fullscreen drivers than have no idea about screen size...
+                do not forget to set WIDTH, HEIGHT, MAXWIDTH,
+     MAXHEIGHT fields if required.

+Registering driver
+==================
+
+   Than just register driver to `driver.c' and you may compile :) You
+may use `ui_template.c' as driver template..

+
+Writting GUI driver
+*******************
+
+   XaoS have builtin GUI. Many operating systems have native gui
+toolkits and XaoS default GUI might look strange there. To avoid this
+problem, you might write external gui program (see eui section) or
+write mappings of XaoS GUI functions. The advantage of external gui
+process in multitasking.  XaoS is not thread safe and GUI must be
+synchronous with calculation.  Also ugly interface code currently don't
+support multiple windows (this should be solved in future).  This
+solution is suitable mainly for those systems, where cooperation of two
+programs sharing one window should be problem (like on Windows).
+
+   To write gui driver you need to fill following structure:
+     struct gui_driver
+     {
+        void (*setrootmenu)(struct uih_context *c, char *name);
+        void (*enabledisable)(struct uih_context *c, char *name);
+        void (*menu)(struct uih_context *c, char *name);
+        void (*dialog)(struct uih_context *c, char *name);
+        void (*help)(struct uih_context *c, char *name);
+     };
+
+   All function have `uih_context' parameter. You don't need to worry
+about it's contents. Just pass it to the called functions that require
+it. This parameter is for multiple window support, that is not
+implemented yet.
+
+   The `setrootmenu' function expected to draw root menu according to
+the menu called `name'. To get menu fields you might use following
+piece of code:
+     #include <ui.h>
+     #include <xmenu.h>
+     
+     ....
+     
+     int i;
+     menuitem *item;
+     for (i = 0; (item = menu_item (name, i)) != NULL; i++)
+        {
+           if (item->type == MENU_SUBMENU) {
+     	      /* This field is submenu. You might call here
+     	         function to construct submenu. item->shortname contains
+     		 name for submenu */
+           }
+           /* add menu field here.
+     
+              You might check flags here:
+              item->flags&MENUFLAG_CHECKBOX
+     	   field have beckbox
+              item->flags&MENUFLAG_RADIO
+     	   field is part of radio button group. In current implementation
+     	   there is one radio button group per menu.
+     
+     	 in both cases you might call: menu_enabled(uih, item) to see
+     	 if item is checked or not.
+     
+              item->name contains field's text
+     
+     	 item->key contains hotkey (one letter string in current
+     	 implementation)
+        }
+   Once field is selected, call function `ui_menuactivate(item, NULL)'
+where `item' is pointer to `menuitem' record of selected field.
+
+   Function `enabledisable' is called when checkbox or radiobutton
+state is changed. The `name' parameter match to `item->shortname' of
+changed field.  So you need to browse all created menus, compare
+`item->shortname' and in case it match, call `menu_enabled' to obtain
+new state. For radiobuttons only enable events are noticed. Your code
+is expected to automatically disable all other radiobuttons in the same
+submenu.
+
+   function `menu' works in similar way to `setrootmenu' but displays
+popup menu.
+
+   Function `dialog' is called for dialogs. The function should look
+like:
+     menuitem *item = menu_findcommand(name);
+     menudialog *dialog = menu_getdialog(uih, item);
+     int i;
+     for(i=0; dialog[i].question; i++)
+     {
+        /* Construct dialog, where left side contains labels with
+         dialog[i].question. Right side contains input entities based on the
+         dialog[i].type. Dialog[i].type is one of the following:
+     
+         DIALOG_INT: integer value input. The default value is: dialog[i].defint
+         DIALOG_FLOAT: floating point input value (long double, where availble
+         exact). Default value is dialog: dialog[i].deffloat
+         DIALOG_COORD: complex value floating point input (two floats), default
+         values are dialog[i].deffloat and dialog[i].deffloat2
+         DIALOG_STRING: string input. default value is dialog[i].defstr
+         DIALOG_IFILE: input file
+         DIALOG_OFILE: output file
+              default mask is dialog[i].defstr
+         DIALOG_CHOICE: choice between various strings.
+              retype dialog[i].defstr to char ** to get pointer to NULL terminated
+     	 array of the choices.
+     }
+   Once dialog is filled by user, gui_driver is expected to allocate
+array of union `dialogparam' `dialogparam':
+     dialogparam *p = calloc (sizeof (*p), nitems);
+   fill selected values. `p[i].dint' is used to pass integer value, or
+number of DIALOG_CHOICE selection, `p[i].number' is used for floating
+point number, `p[i].dstring' for strings and filenames,
+`p[i].dcoord[0]' and `p[i].dcoord[1]' for complex values.
+
+   The string values are expected to be in separate malloced chunks.
+Once array is filled, call `ui_menuactivate(item, p)'.
+
+   The function `help' is used to display help about given topic.  To
+implement it you might eighter convert XaoS help file to some native
+format, or use xshl library to render help page for you. To render xshl
+page use:
+     #include <xshl.h>
+     xshl_line *lines;
+     int getwidth (void *data, int flags, char *text)
+     {
+     	return width of text with given flags
+     	flags is mask of the following:
+              XSHL_BIG - large text
+              XSHL_EMPH - emphatized text
+              XSHL_MONOSPACE - monospaced text (typewriter)
+              XSHL_LINK - line (should be underlined or so)
+              XSHL_WHITE
+              XSHL_RED
+              XSHL_BLACK - color of text (not very meaningfull here)
+              XSHL_RIGHTALIGN
+              XSHL_CENTERALIGN - alignment of the text
+     
+     }
+     lines = help_make (name, getwidth, textheight, largetextheight);
+     if (lines == NULL)
+       lines = help_make ("main", getwidth, textheight, largetextheight);
+   Now you might use `lines' to draw the help. It is pointer to the
+arraw of structures:
+     struct xshl_line {
+       int y;
+       struct xshl_item *first;
+     };
+   `y' is possition of the line from beggining of text and first is
+pointer to the blocks of texts on the line. Last line contains NULL
+pointer in the first section.
+
+   `first' is linked list of the structures:
+     struct xshl_item {
+       struct xshl_context c;
+       char *text;
+       int x;
+       int width;
+       struct xshl_item *next;
+     };
+
+   you might draw text `text' on the possition `x' (and `y' from the
+line record) using style described by `xshl_context':
+     struct xshl_context {
+     	  int flags;
+     	  char *linktext;
+     };
+   `flags' have same meaning as in `getwidth' section. `linktext' is
+name of the next help page in case field have XSHL_LINK atribute.
+
+   As an example of `gui_driver' see win32 driver code.

+
+Writting an external user interface
+***********************************
+
+   This part describes, how to make an external user interface--it is
+the separate program, which makes an window with all menus and dialogs.
+It uses XaoS engine for calculating the fractal as separate process.
+This design brings many advantages--the external GUI implementation
+should have an "native look" for given platform and should contain many
+extensions, such as multiple windows etc. Also all calculation are done
+in the multitasking and user interface is usable even when engine is
+busy.
+
+   The X window provides a way, when program draws into other's
+window--"master" program creates window and sub-window, where he wants
+to have fractal, then calls engine with `-windowid' NUMBER_OF_WINDOW
+parameters. It instead of creating new window uses specified window.
+Most famous example of such cooperation is probably
+ghostscript/ghostview.
+
+   Other windowed environments probably provides similar way for
+cooperation. At others it should be implemented using shared memory, so
+it should work at most platforms, I expect.
+
+   Of course, you might also design UI as separate button box in
+another window, like most of animation players, or Imagemagick have. In
+fact external GUI should be very similar to Imagemagick style.
+
+basic concept
+=============
+
+   The UI implementation has function to disable it's GUI functions.
+Because of the function registry, all it's menus and dialogs are
+described in the fairly simple database. This database is mapped also
+to the scripting language similar to scheme. So the external UI
+implementation just translate the actions into this scripting language
+and sends it trough pipe.
+
+   This commands should be created automatically from the database, as
+well as menus and dialogs, so UI don't need to have special code for
+various XaoS features. At the beginning it should use XaoS' command
+`(print_menus)' to force him to send information about database, then
+build menus using this information.
+
+   For this you need just some equivalent to UNIX pipes, so again I
+expect it is doable at most platforms.
+
+starting XaoS as slave process
+==============================
+
+   One of the first thinks, engine needs to do is to initialize XaoS in
+right mode to work as slave process. For this you need to do several
+thinks:
+
+   * Open the pipe
+
+   * Disable builtin GUI
+
+   * Read menu hierarchy (this is optional--GUI can also have all menus
+     coded into it. But it is not recommended, since it will make
+     problems with future adding new features)
+
+   Opening pipe is done via `-pipe' option. It takes one parameter,
+which is name of FIFO you want use. If you specify "`-'", XaoS will
+read input from stdin.
+
+   To disable XaoS GUI use option `-nogui'. This will disable all menus,
+dialogs and help text.
+
+   To read menu hiearchy just add `-print_menus' parameter and then
+parse XaoS's output. This will print the whole hierarchy. In case you
+are building menus at the time, they are selected, you might prefer
+usage of the command `print_menu'. It prints just one menu without it's
+sub-menus, so it's output should be directly used for building it. It
+takes one string parameter, which is name of menu you want to print. To
+print root menu use `"root"'.  Option should look like this:
+`-print_menu root'.
+
+   Under X Window you need also specify the `-windowid'. Also the
+`-shared' is quite recommended. Otherwise in pseudocolor visuals XaoS
+will create it's own colormap, wich will most probably collide with
+UI's colormap and XaoS or UI will have false colors. If you have any
+idea, how to avoid this, let me know.
+
+   You might also let user to specify some extra parameters from the
+command line. You should simple add the to the end of command line. The
+`-nogui' and `-print_menus' commands must be first for the simple
+reason: XaoS parses it's command line in the early initialization
+stages. Some commands (like `-print_menus') should be processed at this
+time, while others (like `-loadpos' needs to have working engine. This
+commands are queued and processed later, once engine is  initialized.
+In case some such command is before `-print_menus' XaoS will decide to
+keep same order of commands, so it will queue `-print_menus' too. This
+will case, that menus will be printed much later and startup will be
+slower.
+
+   So the proper calling sequence for the user interface under X should
+look like:
+
+     xaos -nogui -print_menus -windowid <id> -share -pipe - [OTHER OPTIONS]
+
+Parsing the menu structure
+==========================
+
+   The structure is printed menu by menu. Each menu contains an header,
+some entries and `endmenu'. Whole listing from `print_menus' is
+terminated by `endmenus'.
+
+   The header starts with `menu' and then contains an identifier of menu
+and full name. Such as:
+
+     menu "fractal" "Fractal"
+
+   Then each entry has its own line. It starts by type, which should be
+`submenu' or `menuentry'.
+
+   `submenu' has similar format to header--fullname of menu and
+identifier.
+
+   `menuentry' adds next few fields. It has an type of entry, which
+should be `normal', `radio' or `checkbox'. `radio' and `checkbox' are
+followed by `on' or `off' specifying whether it is enabled or disabled.
+The radio-buttons don't have explicit information about groups they
+belongs to. For now I just expect, that each menu contains just one
+such group, so it is clear.
+
+   Then set of flags should follow. Currently two flags are defined.
+`dialog', wich specifies, that function has dialog, and
+`dialogatdisable'. By default, dialog for check-boxed functions are
+displayed just in case they are enabled. The second flag reverses this
+behaviour. It is now used for `mandlebrot' function, which behaves in
+this style. When you disable it, user is prompted for the Julia seed.
+
+   So specification should look like this:
+
+     menu fractal "Fractal"
+     submenu "formulae" "mformula"
+     submenu "Incoloring mode" "mincoloring"
+     submenu "Outcoloring mode" "moutcoloring"
+     submenu "Plane" "mplane"
+     submenu "Palette" "palette"
+     menuentry "Mandelbrot mode" "uimandelbrot" checkbox off dialogatdisable dialog
+     menuentry "Perturbation" "uiperturbation" checkbox off dialog
+     menuentry "View" "uiview" normal dialog
+     menuentry "Reset to defaults" "initstate" normal
+     endmenu
+
+Activating functions and dialogs
+================================
+
+   Once the menu structure is built and user selects some item, it
+should be activated. It is done by simple command: `(NAME)'. Once "`)'"
+is sent, command is executed by XaoS.
+
+   Check-boxed functions has one extra parameter--`#t' to enable them
+and `#f' to disable. So if you want enable item `autopilot' send:
+`autopilot #t'
+
+   Radio-buttons don't have any such special parameter--because
+disabling radio-button is nonsense.
+
+   In case, item has flag dialog enabled, engine expects that UI will
+make dialog first, ask user of values and then call function with
+parameters.  UI needs first to know, what parameters function expect.
+It is done by sending command `(print_dialog "NAME")'.  XaoS replies
+with dialog specification very similar to menu specification.
+
+   It has header `dialog' followed by the name of function. Then one
+dialog entry per line is sent. it is started by `dialogentry' followed
+by question UI should display. The is type, which should be one of the
+following:
+`integer'
+     Integer number such as `123'
+
+`float'
+     Floating point number such as `123.123'
+
+`string'
+     String such as `"ahoj"'
+
+`keyword'
+     String such as `'ahoj'. The keywords are mostly similar to string,
+     except they can not contain space. They are used for example for
+     specifying formula type. Strings are used for printing texts etc.
+
+`inputfile'
+
+`outputfile'
+     Here UI should display file selection dialogs. With `outputfile'
+     it is also good idea to check, whether file exist and in this case
+     make some overwriting dialog too.
+
+`onoff'
+     Boolean value (`#f', or `#t')
+
+`complex'
+     Complex value--two floating point numbers such as `123.123 123.123'
+
+`choice'
+     Choice between some keywords. Those keywords are send after
+     `choice' in enclosed the `{' `}'.  Last information at the line is
+the default value in the same format as examples above. For files, the
+default value is in format `"[PREFIX]*[EXTENSION]"'.
+
+   Some examples:
+
+     customdialog "uiview"
+     dialogentry "center:" complex 0.000000 0.000000
+     dialogentry "Radius:" float 0.000000
+     dialogentry "Angle:" float 0.000000
+     enddialog
+     
+     dialog "load"
+     dialogentry "Filename:" inputfile "fract*.xpf"
+     enddialog
+     
+     customdialog "color"
+     dialogentry "Color" choice {white black red }white
+     enddialog
+
+   To activate function, send command which contain function name,
+possible `#t'/`#f' in check-boxes and parameters in the same order as
+in dialog, same format as in examples, separated by the space. Such as:
+
+     (uiview 0 0 0.5 0)
+     (load "text.xpf")
+     (color 'white)
+
+Synchronization
+===============
+
+   In some cases, XaoS can change radio-box and check-box values. (like
+when user pressed a key, or loaded some file). So all changes are sent
+to GUI, wich should inform about this. They are sent to standard output
+in following format:
+
+     checkbox "name" on/off
+     radio "name" on/off
+
+   So your GUI should parse this and change it's menus when necessary.
+
+   Also XaoS's menus can contain more distinct trees. In some cases
+(like when animation replay is active) root of menu structure should
+change. The XaoS sends command:
+
+     root "name"
+
+   Also user can press keys, which normally displayed menus, dialogs or
+help. Then XaoS sends commands:
+
+     menu "name"
+     dialog "name"
+     help "topic"
+
+   All this commands should be taken into account by GUI, or should be
+ignored.
+
+help
+====
+
+   XaoS's help is in the simple hypertext language. In order to
+simplify it's parsing I've made an xshl and help libraries. So making
+of help window should be quite easy. Just call help function:
+
+ - Function: struct xshl_line *help_make (char *COMMAND, int GETWIDTH
+          (void *, int FLAGS, char *TEXT), int WIDTH, int SMALLHEIGHT,
+          int BIGHEIGHT);
+   and you will receive of listings of text with positions, where to
+print into window.
+
+   `command' parameter is topic of help. `getwidth' function is
+function, wich returns width of given text. `width' is width of window,
+`smallheight' is height of small font and `bigheight' is height of big
+font.
+
+   Please ask me for more details if necessary.
+
+   And thats all. Good luck with coding.

+UI-helper library
+*****************
+
+   UI helper library takes care to all XaoS' engine functions and
+features and gives the higher level API, which is quite easy to
+understand. If you want to write completely new user interface
+(replacement for the ugly interface--not just new bindings for native
+menus or external user interfaces) or you want to use XaoS engine in
+your program as an library, you will probably want to use this library.
+
+   It's API has many calls and features. This section gives just brief
+overview of it's calls. Please ask me about details.
+
+initialization
+==============
+
+   To initialize ui helper library, you need to prepare an palette and
+image.  Palette is created using palette library calls `createpalette'.
+Creating truecolor palette should look like this:
+
+       struct palette *pal = createpalette (0, 0, TRUECOLOR, 0, 0, NULL,
+                                            NULL, NULL, NULL);
+
+   For details about creating palettes see `ui.c' or ask me.
+
+   To create image call:
+
+       struct *image img = create_image_mem (width, height, 2, pal,
+                                             pixelwidth, pixelheight);
+
+   This creates image in the memory. If you want to create it in your
+own buffers, you might use `create_image_cont' or `create_image' calls.
+Again see `ui.c'.
+
+   Then it is time to fire up main library:
+
+       struct uih_context *uih = uih_mkcontext (0, img, passfunc,
+                                                NULL, NULL);
+
+   The `passfunc' is called when engine is calculating. It might process
+events and display process information. It should look like this:
+
+     static int
+     ui_passfunc (struct uih_context *c, int display, char *text, float percent)
+     {
+       /*process events */
+       if (uih->display)
+         {
+           uih_drawwindows (uih);
+           /*display */
+         }
+       if (display)
+         {
+           if (percent)
+     	sprintf (str, "%s %3.2f%%        ", text, (double) percent);
+           else
+     	sprintf (str, "%s          ", text);
+           /*display it */
+         }
+     }
+   It might set `uih->interrupt', if it wants to interrupt current
+calculation.
+
+   You also might load the catalog file in order to make tutorials
+working:
+
+       uih_loadcatalog (uih, "english");
+
+   Since this ui_helper library is fully functional and you might enter
+the main loop.
+
+main loop
+=========
+
+   UI helper library does an timing primitives. So it expect an
+standard form of the main loop. It asks the program to display changed
+image when necessary.  Library also use timerlib for it's timing. So
+read section about this library, since you might use it for your
+purposes too.
+
+   Main loop should look like this:
+
+     while (1)
+       {
+         if (uih->display)
+           {
+     	uih_prepare_image (uih);
+     	uih_drawwindows(uih);
+     	/*display current image buffer*/
+           }
+         uih_update (uih, mousex, mousey, buttons);
+         if ((time = tl_process_group (syncgroup, NULL)) != -1 &&
+     	    !uih->inanimation) {
+     	    /*relax given time in usec - wait of events etc..*/
+         }
+         /*and repeat*/
+       }
+
+calling functions
+=================
+
+   UI helper library has many functions declared in `ui_helper.h' for
+various actions. There is too much of them to describe, but their names
+are quite informative, so I hope you will not have problems.
+
+   You might also use XaoS function registry, which does all this stuff
+for you.  You will just draw menus and dialogs based at this registry
+and automatically all features will be available. So if you are writing
+an ordinary user interface, this is the preffered way.
+
+   Note that `ui_helper' library is not reentrant, so you can't call
+most of this function from the `passfunc'. If you are using registry,
+activating function handles this automatically and queues functions
+when necessary.  To process them you need to flush queue in the main
+loop as follows:
+
+     static void
+     processbuffer (void)
+     {
+       menuitem *item;
+       dialogparam *d;
+       if (uih->incalculation)
+         return;
+       while ((item = menu_delqueue (&d)) != NULL)
+         {
+           menu_menuactivate (item, d);
+         }
+     }
+
+closing library
+===============
+
+   This is done using:
+
+       uih_freecontext (uih);
+
+   One implementation of user interface at the top is ugly interface.
+See dirrectory `src/ui'. Another, much simpler is `render.c', which does
+animation rendering.

+XaoS thread library
+*******************
+
+   This description should be useful for those, who want to port XaoS
+into multiprocessor platforms and those, who want to implement some
+filter or other relatively computational expensive code. Note that
+thread library should be mapped into nothread calls, in case host does
+not allows multi-threading or it is not SMP architecture (since this
+library is used only to distribute calculation into other CPUs)
+
+   XaoS thread library is simple map of few functions required by XaoS
+to system library for threads.
+
+   It has following variables:
+
+ - Variable: ethreads
+     This is set to 1 in case that threads are enabled
+
+ - Variable: nthreads
+     Number of threads
+
+   It and following calls:
+
+ - Function: void xth_init (int THREADS)
+     This function initializes threading library (starts threads, sets
+     ETHREAD to 1 and NTHREADS to n. THREADS parameter should be set to
+     0--auto-detection or number of threads users wants. In case threads
+     is set to 1, threading library is disabled and following functions
+     are mapped into those nothread_ equivalents defined in `xthread.h'.
+
+     Note that threads are not identical--there is main thread (one
+     that called xth_init) that communicates with drivers, controls
+     calculation etc. and other tasks that are waiting to orders from
+     main task. They also can't use functions from xthread library.
+
+ - Function: void xth_uninit (void)
+     This function UN-initialize thread library--kills child threads,
+     sets ETHREAD to 0 and NTHREADS to 1.
+
+ - Function: void xth_function (xfunction *FUNCTION, void *data, int
+          RANGE)
+     This function is used in case, engine wants to perform some
+     operation at image in parael. It is expected to wait until all
+     threads are ready and start FUNCTION at all threads including
+     control one with following parameters: DATA--this parameter is
+     same as DATA passed to xth_function, TASKINFO--pointer to structure
+     taskinfo, that is platform depended (defined in `xthread.h') but
+     must have at least field `n', that holds number of thread (control
+     thread has 0 and other numbers in range 1 - NTHREADS). Next two
+     parameters is range of image, function is expected to do action.
+     Xth_function is expected to divided RANGE into NTHREADS equal
+     pieces and pass always start of piece and start of next piece
+     (RANGE in case of last one). Function does not wait for other
+     threads at the end and returns immediately to main thread after
+     FUNCTION returns.
+
+     This function is called approx. 5-10 times per frame
+
+ - Function: void xth_sync (void)
+     This functions waits until all threads are ready for next order
+     from main task.
+
+     This function is called approx 5-10 times per frame
+
+ - Function: void xth_bgjob (xfunction *FUNCTION, void *DATA)
+     This function is expected to behave as follows: look if there is
+     any thread waiting for orders, if so, ask him to call FUNCTION
+     with similar conventions as in xth_function except that range
+     parameters are set to 0.  Otherwise it starts function in normally
+     (at foreground).
+
+     This function is called once per frame.
+
+ - Function: void xth_nthread (struct taskinfo *S)
+     This function should be used to determine number of current
+     thread. Do not use `taskinfo->n' instead since in case threads are
+     disabled, it should be defined to 0 and that allows optimizer to
+     perform better optimizations.  This function should be called by
+     all threads.
+
+ - Function: void xth_lock (int N)
+
+ - Function: void xth_unlock (int N)
+     Lock/unlock lock number N. At least `MAXSEMAPHORS' locks must be
+     available.
+
+     Note that locks are used always for very short fragments of code
+     so they needs to be fast. So spin-locks are maybe better than
+     Dijskra semaphores.  Untested. They are called once per calculated
+     line/row during zoom and once per approx 10 pixels during
+     calculation of new image.
+
+ - Function: void xth_sleep (int N, int L)
+     It is expected to atomically unlock lock L and sleep in queue N.
+     At least `MAXCONDS' queues must be available.  After it is waked
+     up, lock L again. This mechanism is used by calculation of new
+     image algorithm, but it is designed to minimize its calls, so I
+     expect they should be called once or twice.
+
+ - Function: void xth_wakeup (int N)
+     Wake up some thread from queue N. Lock used by sleep calls is
+     locked in this cases. Function should also wake up all threads if
+     such operation is not supported by host API. With luck, this
+     function should not be called at all. It should be called by new
+     image calculation routines in case queue is empty. This happens in
+     case of 50 threads but happens rarely at two or eight threads
+     according to my tests.
+
+ - Function: void xth_wakeall (int N)
+     Similar to wakeup but wake up all threads.

+
+Filters
+*******
+
+   This is a brief description of filter system used internally by XaoS.
+Filters in XaoS provides an object oriented interface to every part of
+XaoS engine. Main filters are: User interface implemented in ui_helper.c
+and zooming engine implemented in zoom.c. Filters are connected into an
+queue--at the beginning there is just two filters here(zoom and ui) but
+later additional filters should be inserted into the middle of queue
+like an stereo-gram generation etc. The queue supports operations like
+remove filter, add filter and initialize.
+
+   In the calculation every filter should use data calculated by filter
+lower in the queue. Data are stored into image. So for example
+stereo-gram filter should use fractal generated by zooming engine and
+create an stereo-gram.
+
+   This makes XaoS's code more flexible and makes easy future
+enhancements like different zooming engine, image rotation, other
+special effects, plug-ins and some other funny stuff since interface of
+each such part is well defined and each filter has quite good control
+over his child.  So stereo-gram filter should change palette, force
+zooming engine to change depth, width and height of calculated image to
+fit his needs and so on.
+
+   This document describes mainly creating of filter like stereo-gram
+generator i.e. filter placed into middle of queue since I don't expect
+there will be many people creating "terminal" filters (zooming
+engines/user interface layer) note that different user interface is
+possible since user interface layer is not the real user interface just
+set of high level functions that should be called by main application
+like set_view. So in case you want to use XaoS as an calculation engine
+in your program this document is probably not for you.
+
+   Each filter is defined by filter_action structures as follows:
+     struct filteraction {
+       char *name;
+       char *shortname;
+       int flags;
+       struct filter *(*getinstance)(struct filteraction *a);
+       void (*destroyinstance)(struct filter *f);
+       int (*doit)(struct filter *f,int flags,int time);
+       int (*requirement)(struct filter *f,struct requirements *r);
+       int (*initialize)(struct filter *f,struct initdata *i);
+       void (*convertup)(struct filter *f,int *x,int *y);
+       void (*convertdown)(struct filter *f,int *x,int *y);
+       void (*removefilter)(struct filter *f);
+     };
+   This structure describes static filter's parameters (like its name)
+and basic set of methods required for communication with resto of XaoS.
+The name field describes filter's name like "An random dot stereo-gram
+generator". Name is displayed by ugly interface in filter's menu. So it
+is expected to be descriptive and shorter than 30 characters. The short
+name is one word long name for filter like "stereogram". This name is
+used by save files, possibly by command line parameters. Simply
+everywhere where user should need to write it and writing long
+descriptive name should be just wasting of time and disk space.
+
+   Flags field is kept for future enhancements and is expected to be 0
+for now.
+
+Creating / destroying of instance
+=================================
+
+   Functions getinstance and destroyinstance are equivalents to
+constructor and destructor in OOP. Getinstance is expected to create
+and fill following structure:
+
+     struct filter {
+       struct filter *next,*previous;
+       struct queue *queue;
+       struct filteraction *action;
+       struct image *image,*childimage;
+       struct requirements req;
+       struct fractal_context *fractalc;
+       void *data;
+       char *name;
+       int flags;
+       void (*wait_function) (struct filter *f);
+       /*stuff for wait_function*/
+       int pos,max,incalculation,readyforinterrupt,interrupt;
+       char *pass;
+     };
+   Altrought this structure seems to be long and complex, most of
+fields are unused at this time and rest of them are filled
+automatically by function:
+
+ - Function: struct filter * createfilter (struct filteraction *FA);
+     That should be used to create instance. Only possibly interesting
+     field is data. It's pointer reserved for filter's internal use. So
+     it should be pointer to filter's internal variables if required.
+     Following is example implementation of get-instance with
+     allocating of such additional structure. In case nothing similar
+     is required you should use directly createfilter at getinstance's
+     place.
+
+     static struct filter *getinstance(struct filteraction *a)
+     {
+           struct filter *f = createfilter(a);    /*create filter structure*/
+           struct stereogramdata *i=calloc(sizeof(*i),1);
+                                                  /*allocate internal variables*/
+           /*initialize your variables here*/
+           f->data=i;                             /*add pointer to internal data*/
+           return (f);
+     }
+
+   The destroyinstance is expected to free memory used by filter
+structure and all internal data of filter. To free filter structure use
+normal free(filter); So implementation of such function should look
+like:
+     static void destroyinstance(struct filter *f)
+     {
+          destroyinheredimage(f);
+          free(f->data);
+          free(f);
+     }
+   The meaning of destroyinheredimage will be described later.
+
+Initialization
+==============
+
+   During initialization phaste each filter says to his parent what kind
+of images it supports (this should depend on images supported by his
+child), parent chooses best supported image format for his purposes and
+gives it to the child. Initialization is done in two pases.
+
+   First pass start by lowest filter in the queue and each filter
+passes to his parents requirement structure.
+
+   Second pass starts by the highest filter and each filter passes to
+child an image and some other stuff. Then calculation should begin.
+
+   Queue needs to be reinitialized after creating, resizing,
+adding/removing of filter and similar operations.
+
+   First pass is implemented using require function. This function is
+expected to take care at child's requirements it received as parameter,
+fill requirements structure and call require function of his parent
+filter.
+     struct requirements {
+       int nimages;
+       int supportedmask;
+       int flags;
+     };
+   The nimages field should be set to 1 or 2. In case it is 2, parent
+filter must pass image with two buffers. Note that in case it is 1,
+parent should pass image with two buffers too.
+
+   Supported mask is mask of supported image types by filter. Image
+types are following:
+`C256'
+     An normal 8bpp image with palette
+
+`TRUECOLOR24'
+     An 24bpp truecolor image with 8bits for each color.
+
+`TRUECOLOR16'
+     An 16bpp truecolor image
+
+`TRUECOLOR'
+     An 32bpp truecolor image with 8bits for each color.
+
+`LARGEITER'
+     An 16bpp image but w/o colors. It is expected to hold number of
+     iterations   it should be also tought as 16bpp grayscale image
+
+`SMALLITER'
+     Similar to `LARGEITER' but 8bpp
+
+   In case you don't worry about palettes, allocations of colors and
+you do just some operation with bitmap, so you worry just about depth
+of image you should use mask of following: `MASK1BPP' for 8 bit images,
+`MASK2BPP' for 16bit and so on.
+
+   The latest field of requirements structure is flags. It mask from
+following constants:
+
+`IMAGEDATA'
+     in case your filter requires data from previous frame untouched.
+     In case   this is not set, filters should reuse your image and
+     change it. But some   filters like and motion blur or zooming
+     engine requires data from previous   frame to construct new, so
+     this flag should be set there is no more flags supported at the
+moment. Function require should also save child's require structure
+into filter->req for later use by initialize pass. So you should look
+like:
+     static int requirement(struct filter *f,struct requirements *r)
+     {
+       f->req=*r;    /*Save an child's requirements*/
+       r->nimages=1; /*Just one image is required*/
+       r->flags&=~IMAGEDATA;/*unset the imagedata field*/
+       r->supportedmask=C256|TRUECOLOR|HICOLOR|REALCOLOR;
+                     /*mask of all supported image types*/
+       return (f->next->action->requirement(f->next, r));
+                     /*call parent*/
+     }
+   Next pass is main initialization. It goes in opposite order(from
+parent to child) and child's infers some stuff from parent like images
+etc...  The initialize structure receives an initdata structure:
+     struct initdata {
+       void (*wait_function) (struct filter *f);
+       struct image *image;
+       struct fractal_context *fractalc;
+       int flags;
+     };
+   an wait_function is function called by filter during calculation that
+lets the parent filters(usually user interface layer) to inform user
+how calculation continues. Image is an image expected to be filled by
+image in calculation phaste. Fractalc is pointer to structure that will
+contain information about fractal during calculation(like formula type
+etc...) Flags is mask of following constants:
+`DATALOST'
+     this is set in case, that data in image was lost(image was cleared
+     or  resized or freshly allocated). Filters that uses data from
+     previous frames  should take care to this flag. Zooming engine for
+     example recalculates  whole image since pixels from previous frame
+     was lost.   Note that data should be lost also in case, filter
+     receives different  image that in previous initialization since
+     some filter behind was  removed.  An inhering process is done
+using function:
+
+ - Function: void inhermisc (struct filter *F,struct initdata *I);
+     This function sets fields in filter structure like as fractalc or
+     wait_func.  Inhering of image is quite complex, since new image
+     needs to be prepared for child. In order to save memory it is
+     highly recommended to use same image or at least same memory for
+     data when passing to child. But this is not allays possible.
+     Following function implements heuristic to do this:
+
+ - Function: int inherimage (struct filter *F,struct initdata *DATA,
+          int FLAGS, int WIDTH, int HEIGHT, struct palette *PALETTE,
+          float PIXELWIDTH, float PIXELHEIGHT)
+     You should call this function in your initialize pass. It fills
+     image and childimage in filter structure, prepares initdata for
+     child and creates image for child. Note that it should fail in
+     some cases and return 0. In this case filter is expected to
+     interrupt initialization and return 0 too.
+
+     An FLAGS parameter is mask of following constants:
+    `IMAGEDATA'
+          in case your filter requires data from previous frame
+
+    `TOUCHDATA'
+          In case your filter touches data in output image. This is
+          very usual but   there is some filters (like interlace or
+          subwindow that don't)
+
+    `NEWIMAGE'
+          Set in case your filter can not deal with shared images
+          (images that have   input data in same memory are as output)
+     WIDTH and HEIGHT should be set to 0 in case you want same
+     width/height as in parent image or width and height of image you
+     want to pass to child.  PALETTE is palette of image you want to
+     pass. Set to `NULL' if palette should be inhered from parent's
+     image (usual).  PIXELWIDTH and PIXELHEIGHT specifies physical size
+     of pixel in centimeters.  If set to 0 they are inhered from
+     parent's image.
+
+   In case you use inherimage mechanism you also must call
+destroyinheredimage in destroyinstance function and updateinheredimage
+at the beginning of calculate function.
+
+   Example implementation:
+     static int initialize(struct filter *f,struct initdata *i)
+     {struct stereogramdata *s=f->data;
+       inhermisc(f,i);
+       if(!inherimage(f,i,TOUCHIMAGE,0,0,NULL,0,0) return 0;
+       /*initialize here*/
+       return(f->previous->action->initialize(f->previous,i));
+     }
+   Also note that fractal context hold pointer to fractal palette. In
+case You don't change image palette everything is OK. But in case
+child's image differs from parents image, there should be two
+behaviors--fractal's palette is child one (this should be common for
+example in conversion filters ( 8bpp to truecolor etc)) or fractal's
+palette is parent's one (like in edge detection filter). By default
+fractal's palette is kept to parent's one.  This should be changed by
+setfractalpalette call. It has two parameters--filter structure and
+palette. When you pass as palette child's palette, fractal's palette
+will be changed to child. In case you pass NULL. Changing of palette
+will be disabled (like in motion blur filter in 8bpp mode).  Note that
+this is changed just in case you still have access to fractal palette.
+Some parent should redirect palette before. Than this function does
+nothing.
+
+Caluclation
+===========
+
+   Main calculation is done using doit function. It is expected to call
+child's calculation function when required and apply filter at output.
+It receives flags. Only flag in `INTERRUPTIBLE' for now. It is mainly
+for zooming engine so I do not describe it here. But filter is expected
+to pass this flag to child. Next parameter is time in milliseconds that
+expired since last doit call. It should be used to calculate speed of
+animation.
+
+   Calculation loops returns flags. Flags is mask from following
+constants:
+`ANIMATION'
+     in case filter performs some animation and expect that calculation
+     will be  called again soon
+
+`CHANGED'
+     in case something changed in output image (usual)
+
+`INEXACT'
+     This is enabled by zooming engine in `INTERRUPTIBLE' mode in case
+     that time  exceeded.
+
+   An doit function changes image. Image structure contains following
+fields significant for you:
+`bytesperpixel'
+     number of bytes per pixel (image depth)
+
+`palette'
+     palette of image.
+
+`currlines'
+     array of pointers to beginnings of every scanline of image
+
+`oldlines'
+     array of pointers like currlines but for previous image in case
+     doublebuffering is enabled
+
+`nimages'
+     set to 2 in case doublebuffering is active
+
+`flipimage'
+     pointer to function that flips oldlines and currlines.
+
+   palette structure contains following significant fields:
+
+`type'
+     type of palette/image (`C256', `TRUECOLOR' etc...)
+
+`size'
+     number of allocated entries
+
+`pixels'
+     array of allocated entries. Conversion table from number of
+     iteration  to pixel value.
+
+`rgb'
+     Rgb values for pixels (`NULL' for `TRUECOLOR', `HICOLOR' and
+     similiar types)
+
+   To make easier writing calculation loops for different depths
+`pixel8_t', `pixel16_t' and `pixel32_t' are predefined. You also can
+use include system as in edge detection filter, that lets you write
+calculation loops just once and use cpixel_t and it will be compiled
+for every bitmap depth.  See edge detection filter (engine/edge.c and
+engine/edged.c) for implementation details.
+
+Conversion
+==========
+
+   Convertup and convertdown functions are used for converting screen
+coordinates to position in fractal and back. Convertup is function that
+receives coordinates in child's image and is expected to convert them
+into coordinates in parents image and call parent's convertup function.
+
+   Convertdown is reversed(from parent to child).
+
+   In case coordinates respond 1:1 you should use convertupgeneric and
+convertdowngeneric. In other case implementation should look like:
+
+     static void convertup(struct filter *f,int *x,int *y)
+     {
+         *y*=2;
+         *x*=2;
+         if(f->next!=NULL) f->next->action->convertup(f->next,x,y);
+     }
+     static void convertdown(struct filter *f,int *x,int *y)
+     {
+         *y/=2;
+         *x/=2;
+         if(f->previous!=NULL) f->previous->action->convertdown(f->previous,x,y);
+     }
+
+Removing of filter
+==================
+
+   Before filter is removed from queue, removefilter function is called.
+It is expected to clean up thinks filter changed. Should be NULL in
+most cases.
+
+Registering of filter
+=====================
+
+   Once filteraction structure is filled, filter is done and you should
+try to enable it. To enable it in user interface you need to edit
+ui/ui_helper.c, add filter into uih_filters structure and increase
+uih_nfilters.  Note that order of filters in uih_filter is significant,
+since same order is kept in filter queue, so you should specify if you
+want to be called before/after filter xy.
+
+   Then it is high time to start experimenting.
+
+   Good luck!

+Algorithm description
+*********************
+
+   The main idea behind XaoS is that it is not required to calculate the
+whole image every frame. Most pixels are already calculated in the
+previous frames. You usually don't have exactly the pixels you want,
+but all within a range lower than a step between pixels are acceptable.
+That is why the image flicker a bit and why points do not blink
+randomly as in recalculated animations.
+
+   This document describes some of the most important algorithms in XaoS
+   * Saving Previous Pixels
+
+   * Approximation Algorithm
+
+   * Moving Pixels to New Positions
+
+   * Calculating New Pixels
+
+   * Symmetry
+
+   * Calculation of Mandelbrot Set
+
+   * Dynamic Resolution
+
+   * Autopilot
+
+Saving Previous Pixels
+======================
+
+   Ideally, all recalculated points should be saved and used for
+building successive frames. I could not figure out a practical way to
+implement this. To save all frames for half an hour would require 24 Mb
+of memory, and searching the saved frames would be more computationally
+expensive than recalculating an entirely new frame.
+
+   One way was later used by program Frang. It remembers all pixels as
+x,y and value fields and when it builds new image, it draws all pixels
+to it and then browses image and fills it by new pixels. Possibly some
+rle cache should be used for calculated pixels. Frang actually uses
+algorithm, that takes away pixels out of screen, so it behaves exactly
+in same way as algorihm described here. At the other hand, this method
+seems to require much more memory than XaoS algorithm and drawing
+pixels/browsing image cost quite a lot, so algorithm described here
+seems to be faster. Since it never requires examining of whole image
+and new image is constructed using block move operations.
+
+   For this reason only the last generated frame is used as reference.
+This way the memory requirements are proportional to xsize * ysize. It
+can be shown that this method is only about 2-5% slower during zooming.
+Of course unzooming back to once browsed areas is much slower.
+
+   Because only the previous frame is used, another optimization can be
+performed: Imaginary and real parts of the calculated image are not
+precise since they are the result of successive iterations of same
+algorithm. In order to prevent errors from being distributed to the
+following frames their exact coordinates need to be known.
+Fortunately, it isn't necessary to save their values since it is known
+that all real components in a row and all imaginary components in a
+column are equal. Thus, the only things that must be saved are the real
+components for every row and the imaginary components for every column.
+
+   This allows for a substantial speed-up in approximation because the
+calculation requires less data. Of course, some rows and columns fall
+out of the threshold and new ones need to be calculate to fill in the
+gaps in the frame.
+
+   Obviously, much less work is done. There are only xsize + ysize
+calculations instead of xsize * ysize. So the main loop in XaoS looks
+like this:
+   * Make approximations for rows
+
+   * Make approximations for columns
+
+   * Move old pixels to their new positions
+
+   * Calculate pixels for which there is no good approximation for
+      their row
+
+   * Calculate pixels for which there is not good approximation for
+       their column but there is one for their row
+
+Approximation Algorithm
+=======================
+
+Introduction to problem
+-----------------------
+
+   You can see that the approximation algorithm is central to the
+implementation of XaoS. If the guess is incorrect the image will look
+strange, boundaries will not be smooth and the zoom will flicker. On
+the other hand, if it adds more new rows or columns than required,
+zooming will become much slower. Also, in the instance of doubling
+(i.e., using an old row or column more than once) the resolution will
+lower. It is important to keep the increasing imaginary and real
+components in the correct order. If a row and column of complex
+coordinates follows one with higher coordinate values an improved
+approximation can be attained by swapping their values.
+
+   The algorithm needs to be relatively fast. It is only used for xsize
++ ysize values but if its speed is proportional to O(n^2), it can be
+slower than a whole recalculation of the image. Speeds of O(n) or O(n *
+log(n)) are acceptable.
+
+Some simple algorithms to solve it
+----------------------------------
+
+   Initially, a very simple algorithm was used:
+
+   Find the old row/column nearest the row/column that needs to be
+regenerated. If the difference between them is less than one step
+(step = (end - beginning) / resolution) then use it. Otherwise,
+recalculate a new one.
+
+   Finding the nearest row/column pair is very simple since it is always
+greater or equal to the pair needing to be generated.
+
+   Surprisingly, this simple algorithm has almost all the problems
+described above. Doubling was fixed by lowering the limit to step / 2.
+This cause a considerable slowdown so the limit was returned to step.
+Instead, the algorithm was changed to search for only row/column pairs
+that are greater than the previous frame's row/column pairs. This is
+the algorithm that was used in version 1.0
+
+   This algorithm still added to many new rows and columns and did not
+generate smooth boundaries. For version 1.1 a heuristic was added that
+preferred approximating rows/columns with lower values. This way it did
+not occupy possible rows/columns for the next approximation. The result
+was a speedup by a magnitude of four. In versions 1.1 to 2.0 many
+improvements were made to the heuristic to give it added performance.
+The following example tries to explain how complicated the problem is
+(O is the old coordinates and X is the values to be approximated):
+             X1        X2        X3        X4        X5        X6        X7
+     O1 O2                    O3 O4 O5                   O6 O7 O8
+
+   The normal algorithm will aproximate X1 by O2, X3 by O4 but nothing
+more. For the algorithm with threshold step instead of step / 2:
+
+       O2 to X1
+       O3 to X2
+       O4 to X3
+       O5 to X4
+       O6 to X5
+       O8 to X6
+
+   But this will fail with X7. The second algorithm which relies on
+lower values will do the following:
+
+       O1 to X1
+       O3 to X2
+       O4 to X3
+       O5 to X4
+       O6 to X5
+       O7 to X6
+       O8 to X7
+
+   O1 to X1 is wrong. And there is many and many other situations that
+may occur. But you may see that the normal algorithm will calculate 4
+new rows/columns but the heuristic saves all of these calculations.
+
+Current algorithms used
+-----------------------
+
+   In version 2.1 work on this heuristic was disabled after I discovered
+a surprisingly simple algorithm that solves all these problems. First I
+decided to define exactly what is best approximation. This should be
+done by defining a price for every approximation and choose the
+approximation with the lowest price. Prices are defined as such:
+
+   Approximating row/column x by y costs dist(x, y) ^ 2.
+
+   This prefers two smaller approximation errors before a single larger
+error and describes my goal quite well.
+
+   The cost for adding a new row/column specifies when it is better to
+do a bad approximation and when to add a new row/column. I use (4 *
+step) * (4 * step). This means that the approximation is acceptable when
+dist(x, y) < 4 * step. Otherwise, adding a new row/column costs less.
+Now the best approximation is known. All that is required is a fast
+algorithm to do this. Surprisingly, this is possible in linear time
+using a relatively simple dynamic algorithm. It uses approximations of
+length < n to make a guess at the length of n. It can start by
+approximating one row/column and then again for two, three up to
+xsize/ysize rows/columns.
+
+   The algorithm starts by calculating prices for all possible new
+positions for old row/column 1. Because of the pricing there are
+maximally 8 new positions. (Other ones must cost more than adding new
+row/column). Of course it is possible that there are no new positions.
+
+   For calculating the price of approximations for row/column 2 I may
+use previous one: Try new position n. Calculate the price and add the
+best approximation for the previous (row/column 1) one that uses a new
+position lower than n(prohibits doubling or swapping). This should be
+one of 8 positions or eventually adding of new one and not using
+row/column 1 at all.
+
+   The same method can be used for the rest of the rows/columns. At the
+end the best price may be found for the last row/column and return by
+the way it was calculated. (For this I need the saved "calculated
+using" values.) At this step the best approximation has been determined.
+
+   To fill the table, 9 * n steps are required and n steps to backtrack
+best approximation. The only problem is that this algorithm is still a
+little slow (chiefly because of slow memory access on Intel
+architectures). -But with some optimizing it works well.
+
+   This algorithm is almost perfect except that it occasionally adds new
+rows/columns to the wrong locations. It does not prefer to add new
+rows/columns into holes. But it does not seem that this is the real
+problem. The last optimization made was based upon the face that added
+rows/columns do not have the exact real and imaginary components
+calculated by (beginning + x * step) but lies at the average of left
+and right neighbors. This makes the boundaries smooth and distributes
+coordinates better. It also has the added benefit of making the input
+better for future approximations.
+
+   Another danger during implementation if this algorithm is that
+adding new rows/columns into their ideal positions should cause
+miss-ordered results, since some rows/columns should be off more that
+is distance between them.  To avoid this, I use algorithm that always
+examine start and end of block of new rows/columns and linearly
+interpolates value between them. Special care needs to be at the blocks
+that start at the beginning or overs at the end.
+
+   Implementation should be much faster using custom fixedpoint
+routines--first recalculate values that 0 means start of image and
+65536 means end.  Than calculation is much cleaner. Values <0 and
+>65536 are of screen, calculation is independent at scale and many
+thinks should be recalculated--like tables for calculating price from
+distance.  Also dividing main loops into many specialized parts and
+avoiding filing unnecessary parts of table helps. So current algorithm
+in XaoS is about 5 or 6 times faster than first naive implementation.
+
+Moving Pixels to New Positions
+==============================
+
+   Since XaoS is using the approximation algorithm the following table
+is filled for every row/column:
+   * calculate
+
+   * oldpoint
+
+   * position     calculate is 1 if the current row/column is new and
+needs to be calculated or 0 if no old pixels need to be moved. oldpoint
+is a pointer to the old row/column that corresponds to the new one. This
+pixel needs to be copied to the new location. position is the real and
+imaginary components of the coordinates used for future approximations.
+Because almost all points will be moved, the solution seems to be
+simple: for every new point look at the row and column table; copy it
+if required.
+
+   There is the problem that this minimally needs three memory reads for
+every pixel (read calculate, oldpoint and index of old point). This is
+too slow, so a small optimization is performed. Instead rewriting the
+piece of code in assembly, normal memcpy is used to move blocks of
+pixels to their new locations. This minimizes the internal loop and
+access can be done more quickly since memcpy is usually optimized for
+each architecture.
+
+   Using the row table, a list of blocks to move for every row is
+created. With this new table all the pixels can be moved quickly. This
+increased the speed of XaoS about four times and made this function so
+fast that it is no longer a problem. (In fact, it takes much less
+processing than all other parts of XaoS.)
+
+Calculating New Pixels
+======================
+
+   The above optimizations make XaoS very fast, but another 30% increase
+in speed is acquired by using a clever method for calculating the new
+pixels. Many methods are known for saving calculations during the
+generation of fractal images. The most powerful is boundary detection.
+It relies on the fact that the Mandelbrot Set is connected with lakes.
+You need only one pixel at the boundary, then traverse the whole set
+and then fill the solid area inside. This method saves many
+calculations but is too complex for adding just one line. Many claim
+that it does not introduce any errors, but this is not true. It is
+possible for a connected part of the lake to be so small that it is not
+visible in smaller resolutions. In this case, boundary detection misses
+the whole area. This algorithm is actually used just for calculating of
+new images (i.e. at the startup).
+
+   XaoS uses modification of method known as solid guessing. The pixels
+at the boundaries of a rectangle are calculated. If they are all the
+same you may assume that this rectangle does not does not contain
+anything and fill it.
+
+   This algorithm is further modified to operate on added lines. For
+this it is at least as good as boundary detection and produces more
+tangible errors. When adding a single line, the upper and lower line
+may be examined for the nearest three pixels. If they are all the same
+then it is assumed that 9x9 pixels are the same. This disables all
+calculations inside solid areas and calculates as many points as
+boundary detection. The only possibility of creating a larger error
+with this method as opposed to boundary detection is in the instance
+that the shape of the set is so sharp that it does not set any of the
+tested points but comes from the right (i.e., uncalculated) location.
+This situation is not very common.
+
+   Later, rules were added for new rows and columns that crossed each
+other. In this instance you can test only four pixels. This situation
+is very rare. It is hoped that it does not introduce many errors.
+
+   If multiple blocks of new lines need to be calculated there are not
+reference pixels to use for solid guessing. Interlacing does the trick.
+By calculating the odd lines without any guessing, the guessing
+algorithm is now possible for the remaining uncalculated lines. This
+simple trick saves about 30% of the calculation of the main Mandelbrot
+image.
+
+   A similar approximation can also be done for the X coordinate. This
+makes it possible to improve solid guessing at even pixels because all
+surrounding pixels are available, further reducing errors.
+
+Symmetry
+========
+
+   Many fractals are horizontally or vertically symmetrical. This is
+implemented in the approximation code. When there is no good
+approximation available, try to mirror the opposite side if the line is
+available.
+
+   This method primarily speeds up the initial image.
+
+Calculation of the Mandelbrot Set
+=================================
+
+   Internal Mandelbrot calculation loop is unrolled--it calculates
+first 8 iterations using normal method and then it expects that number
+of iterations will be probably large so it switches into mode, where it
+calculates iterations in block of 8 with one bailout test at the end.
+When bailout is received, saved values from previous iterations is
+restored and last 8 iterations are recalculated slowly to get exact
+values. This helps a lot especially at Pentium, where conditionals in
+floating point code is slow.
+
+   Another stuff is periodicity checking. XaoS has both version of
+loops--with an without periodicity checks. In most cases it uses
+nonperiodicity checking version. Periodicity check version is used just
+in case, some inside set pixel has been found during solid guessing
+paste around. This is done mainly because periodicity checking version
+of loop is significantly slower.
+
+Dynamic Resolution
+==================
+
+   The above optimizations often do not help enough and image
+calculation is still too slow. One option was to reduce the framerate,
+but a framerate lower than 5 frames per second is unbearable. Another
+option is simply to calculate only the details that can be determined
+within a time interval.
+
+   Rows/columns not calculated are simple approximated by referencing
+the nearest other row/column. The result is an image with larger pixels.
+One problem is the fact that the order of calculating the rows/columns
+is significant. Previous versions of XaoS simply calculated all rows
+from top to bottom and then columns from left to right. Using the
+dynamic resolution code with this algorithm would result in distorted
+images. This was solved by adding priority to every row/column and
+calculating the high priority row/column first. The algorithm for
+adding these priorities is as follows:
+   * Find middle row/column of uncalculated block. Priority is the size
+        of the block (in floating point coordinates)
+
+   * Start function for left block and right block
+
+   This function produces quite good results. It tends to make same size
+rectangles on the whole image and does not depend on resolution.
+
+   Another interesting optimization is that during the zoom it is more
+advantageous to calculate rows/columns in the center of the zoom
+instead of the borders since these will be in the viewport longer and
+the user is usually focusing on center of the zoom anyhow.
+
+   This is done by simply adding to the calculated priority
+normal_priority / (abs(newposition - oldposition) / step + 1). This
+prefers rows/columns that do not move a great deal. Of course,
+unzooming uses the formula reversed.
+
+   The last variable to consider is the time interval for one frame.
+Setting it too low makes the calculation slow. Setting it too high
+makes the framerate too low. So the amount of time spent in other parts
+of the program is calculated and multiplied by 5 to determine the
+interval. If time is then lower than 15FPS, 15FPS is used instead,
+since slower animations are unacceptable. At the other hand if it is
+higher than 35FPS, it is set to 35FPS, since higher framerate is just
+wasting of computer resources. When image is not animating, this values
+is changed, so framerate is choose between 5FPS and 15FPS. This caused
+that images are calculated quickly after zooms stops.
+
+Autopilot
+=========
+
+   Another interesting algorithm controls the autopilot. It is actually
+quite simple. Interesting parts are found at the boundaries of the set.
+It randomly looks around and zooms to the first area containing both
+outside and inside set points. Some fractals (such as the Newton) do
+not have points inside the set at all. In this case it selects a point
+where many (more than 2) different colors are around. (i.e., It zooms
+into noisy areas.)
+
+   In the instance that there are no such areas, the autopilot will
+unzoom. Also detects oscillating.
+
+   Current implementation also does detection of out of range numbers
+and randomly choosed points are choosed near the old one, to avoid too
+often changes of direction.
+
+SMP support
+===========
+
+   Since version 3.0 XaoS supports SMP. This is done using threads.
+Most of XaoS routines should be threaded easily--for example
+moveoldpoints just divides image into n equal part and each part is
+proceeded by one processor.  Only unthreaded part is realloc table
+calculation routines. I don't see any way to paraelize it except it
+calculates both--x and y approximation at one time (using two
+processors).  Another interesting algorithm to paraelize is boundary
+trace. See comments `btrace.c' for discussion about current
+implementation.  Only problem of current implementation I see is
+possibility, that calculation is divided into too many parts (realloc
+tables, move points, calculate, symmetries, dynamic resolution) and
+tasks needs to synchronize between each part. So this should be too
+slow at real SMP box.

+
+The timer library
+*****************
+
+   Timer library is library I did for timing in XaoS. But I found it
+useful in many other programs (like demonstrations, games, animation
+players and all other stuff that needs to be timed). So you should read
+this description and possibly use it in your application and save some
+coding time.
+
+   There is many ways how to design of such timed application (game)
+
+  1. read user input, move badies, display and again this way has one
+     disadvantage. Speed of game depends on speed of computer.  This
+     was acceptable in old times where only processor was Z80 :) but now
+     with wide variety of various hardwares such internal loop is
+     unacceptable
+
+  2. read user input, measure time since last loop and calculate step
+     for badies, move badies for set step, display and again.  This way
+     fixes problem with speed. But moving badies just for calculated
+     step, that should differ a much is quite complex, usually
+     introduces complex calculation, floating/fixedpoint math and other
+     unnecesarry stuff that makes program long and introduces many bugs.
+
+  3. Set the fixed framerate that is high enough to make game smooth
+     but low enough to do whole internal loop in time. So internal loop
+     should look like: read user input, move badies, display, measure
+     time spent in loop an sleep rest of time until next frame.  This
+     is quite popular scheme but has another disadvantage--game can not
+     be designed to use whole CPU power since on slower computers
+     internal loop should take longer time that is reserved for one
+     frame. Game will run slowly again.
+
+  4. To take away disadvantage of previous method, many games times just
+     moving of badies and user input. Other stuff like displaying
+     should be done in rest of time. In DOS games moving and user input
+     is often at asynchronous interrupt and drawing runs as main loop.
+     This solves problem in case that drawing of game takes
+     significantly longer time than moving of badies. This is quite
+     usual so this scheme works well.
+
+  5. previous scheme still has one problem--since timer interrupt works
+     asynchronously, there should happend many race condition, in case
+     moving takes longer time than time reserved from frame, computer
+     can crash. So this scheme should be enhanced into synchronous one
+     with exactly same result but avoiding problem with race condition:
+
+     read user input, measure time spent by loop and calculate how many
+     simulated frame interrupts activated since last activation, if
+     zero sleep until simulated interrupt, move badies as many times as
+     required, display
+
+     this is an combination of 4 and 3 and seems to be most comfortable
+     way for writing games but since main loop is now quite complex
+     many games don't do that.
+
+  6. there is still one small problem. Method 5 expect that moving takes
+     significantly lower time that displaying. This may not be truth.
+     Simple work around is to write moving routine, that should move
+     for x moves by faster way that calling move x times. This is often
+     possible and makes easy extension to scheme 5. This scheme allows
+     you to use very large maximal framerate (say 100FPS) and to have
+     same results as method 2 (that is maximally exact method)
+
+   As you can see, designing of main loop isn't so easy. This is just
+very simple example. More advanced application for example should want
+to move one set of badies at one framerate and other at different
+framerate. This requires two such timings. Another complication is that
+there is many different ways to measure time exactly at different
+platforms. Under Linux you can measure using gettimeofday but under DOS
+this is exact just to 1/18 of second and thats too low for smooth
+animation and so on.
+
+   Thats why I decided to design portable easy to use timer library,
+that makes easy to implement all described method, combining of them
+and much more.  During design I taken care at the following thinks:
+quality of timing, how easy to use it is, speed, portability and to
+minimalize inexpected situations (like race conditions in asynchronous
+interrupts and so on)
+
+The name of game
+================
+
+   Timer library operates with "timers". They should be created, you
+should measure time since last reset, pause them or set "handler" and
+"interval".  But handler is not activated at given interval yet. Since
+timer library is not asynchronous, you must activate them.
+
+   For activating is used "groups". You should process group at some
+place in your program. Then all timers in group are checked and their
+handlers activated if required. When time spent since last activation
+is higher than interval, handler is activated more times. Also interval
+to next invocation is calculated to keep frequency.  Simple scheduling
+is performed at handler--handler is activated just once and then all
+other timers are checked before it is activated again. You should also
+define an multihandler--handler that is activated just once and
+receives argument how many intervals has left.
+
+   There is two special groups--`asyncgroup'. Timers in this group are
+activated asynchronously like from interrupt. It is not recommended to
+use it, since it brings many problems and usually isn't required. Also
+it does not work at many platforms. `Syncgroup' is the default group.
+Program is expected to process is quite often. In case you don't need
+to use more groups, you should use this one.
+
+   Time in timerlib is bit strange, since it does not flow continuously
+but jumps. It is updated every time you call `tl_updatetime'. I used
+this way in order to minimize context switches but later I found this
+scheme very useful, since you should lookup timer, do something and
+then reset it and don't wory about time spend between lookup and reset
+since it is 0 in case you did not called tl_updatetime. This helps to
+keep frequency of timers exact w/o any errors caused by such
+situations. At the other hand you need to call tl_updatetime at least
+once in your main loop.
+
+   Maybe you don't know why to create more groups, but I found it quite
+useful.  For example an autopilot in XaoS has such special group--I
+need to call it approx. every 1/20 of second but just at one place in
+program. Invoking of autopilot when calculation is active should
+produce incorrect results, so I have special group for autopilot and
+process just at one place where I am sure it is safe.
+
+   Timers should be also emulated. You should stop them and then
+control flow of time for given timer. This should be quite useful for
+example when you want precalculate animation at given framerate.
+
+   To control group of timers, you might create "emulators". It is just
+another time controlled by you. It is useful in cases you want to
+emulate fixed framerate (for animation rendering) or such.
+
+Time functions

+
+XaoS function registry
+**********************
+
+   XaoS has an ui helper library, which provides functionality provided
+by user interface. All it's useful functions are registered into
+central registry.  This registry is used to generate menus and dialogs
+as well as command line options or scripting language. So it is very
+significant think in XaoS design.
+
+   Not only those who want hack XaoS ui-helper layer needs to know
+this, but also authors of drivers should use this to add new driver
+depended functions into XaoS's menu. Also external user interface is
+based at this.  Main idea behind external user interfaces (currently
+one for TCL/Tk and Gtk is under development) is following: XaoS
+transfers it's registry to interface (using simple description
+language). User interface starts XaoS in it's window and builds menus
+and dialogs based at this registry. Then once user select some
+function, it creates an command for scripting language and sends it back
+to XaoS' engine.
+
+   So knowledge of this part is essential for many developers. Please
+take care for this part.
+
+   The implementation of registry is in file `xmenu.c', header is
+`xmenu.h'. Mainly for historical reasons it speaks about menus and
+dialogs. (It was designed for the GUI at the beginning) I am keeping
+this terminology, since it is quite clean and easy to understand
+instead of talking in some cryptic abstract term.
+
+Function description
+====================
+
+   To add function into database, you need write it's description into
+menuitem structure. It has following prototype:
+
+     typedef struct menuitem
+       {
+         char *menuname;
+         char *key;
+         char *name;
+         char *shortname;
+         int type;
+         int flags;
+         void (*function) ();
+         int iparam;
+         void *pparam;
+         int (*control) (struct uih_context *);
+         menudialog *(*dialog) (struct uih_context *);
+       }
+     menuitem;
+
+ - Variable: menuname
+     Name of menu (or category) function belongs in. The root of all
+     categories is called `"root"'. XaoS alternativly uses an
+     `"animroot"' when animation replay is active. If you are adding an
+     function, it is better to add it into some subcategory like as
+     `"ui"' (it will be placed into UI menu then) or create an new
+     category for your functions if needed. It will appear as submenu
+     in main menu in the UI.
+
+ - Variable: key
+     Ascii code of hotkey to activate this function. Use `NULL' if none.
+
+ - Variable: name
+     Longer name of functions used in the menu entry, or `xaos --help'
+     listing
+
+ - Variable: shortname
+     One-word name of function used in command language and references
+     to function.
+
+ - Variable: type
+     type of function--this is not return type. Type should be one of
+     following constants:
+    `MENU_SUBMENU'
+          An submenu. This is not real function, but name for submenu.
+          You might fill    the KEY, NAME, SHORTNAME functions. An name
+          of this new    submenu is placed in the field PPARAM.
+
+    `MENU_NOPARAM'
+          An normal function without any parameters. When actived,
+          function    FUNCTION with just an pointer to `uih_context'
+          will be called.
+
+    `MENU_INT'
+          This should be used to simplify entering of more similar
+          functions (handled    by just one universal function in the c
+          code). This function is handled in    same way as
+          `MENU_NOPARAM', but also in one integer parameters taken
+          from `iparam' is passed.
+
+    `MENU_STRING'
+          Similar to `MENU_INT' but uses string instead of integer.
+
+    `MENU_DIALOG'
+          If you function needs some paramters, use dialog structure to
+          describe    them. In scripting language your function will
+          have parameters then, in    user interface dialog will be
+          displayed. PPARAM must then point to    array of dialog
+          entries. Witting them will be described later.     If your
+          function has just one parameter described in dialog
+          structure, it    will be called in normal c way--if you want
+          string parameter, one    pointer pointing to string (in
+          addition to `uih_context') will be    passed to the functions.
+
+          In case of multiple parameters are requested, it is
+          impossible to call    function in c way without special
+          wrapper for each such case. So it will    receive pointer to
+          array of `dialogparam' unions, wich contains    one entry for
+          each parameter. `dialogparam' is declared as follows:
+               typedef union
+                 {
+                   char *dstring;
+                   int dint;
+                   number_t number;
+                   number_t dcoord[2];
+                   xio_path dpath;
+                   void *dummy;
+                 }
+               dialogparam;
+
+    `MENU_CDIALOG'
+          In some cases, it is useful to add some context specific
+          default values    to the dialog structure. In this case you
+          might use this type instead. In    this case function DIALOG
+          is called first, and it is expected to    return pointer to
+          correct dialog structure. Dialog structure must lie in
+          static storage (since it is not freed) and always must have
+          the same    fields, just differ in the default values.
+          Also this function must work correctly even in the case
+          pointer to    `uih_context' is `NULL', since it is often
+          called in the    initialization stages (parameter parsing
+          etc.)
+
+ - Variable: flags
+     Flags are used to set additional information about function:
+    `MENUFLAG_CHECKBOX'
+          Some features act like check-box--i.e. by one calling of
+          function they are enabled, second call disables this. In menu
+          it is useful to add an check-box for this function indicating
+          whether feature is on or off.
+
+          And thats exactly what this flag does :). You need also
+          define the function CONTROL wich return's `1' when enabled
+          and `0' when disabled.  In order to let external GUI's work
+          correctly you need also call `uih_updatemenus("name")' every
+          time state of this function changes.
+
+          In the scripting language this adds an first parameter, wich
+          if `#t' or `#f'.  Engine then calls function just when it is
+          necessary. For `#t' dialog is requested, with `#f' function
+          is called just as `NOPARAM'. I.e.  dialog is displayed just
+          when enabling feature.
+
+    `MENUFLAG_DIALOGATDISABLE'
+          In checkbox display dialog when this feature is disabled
+          instead when enabled.
+
+    `MENUFLAG_RADIO'
+          Other features act like radio-button. Control function in
+          this case receives same parameter as defined for `MENU_INT'
+          or `MENU_STRING' types and is expected to return `1' when
+          enabled. You also need to call `uih_updatemenus' when
+          changed. No special parameter is added in the scripting
+          language.
+
+    `MENUFLAG_INTERRUPT'
+          Interrupt current calculation when this function called (it
+          is used by functions with causes recalculation of screen)
+
+    `MENUFLAG_INCALC'
+          By default XaoS queues functions and calls later when they
+          are activated in caluclation. This flag disables this feature.
+
+    `MENUFLAG_ATSTARTUP'
+          By default XaoS queues functions and calls later when they
+          are activated as command line parameters (in time engine is
+          not fully initialized yet).  This flag disables this feature.
+
+    `MENUFLAG_NOMENU'
+          Function will not be visible in the menu
+
+    `MENUFLAG_NOPLAY'
+          Function will not be available as command in scripts
+
+    `MENUFLAG_NOOPTION'
+          Function will not be available as command line option
+
+Initializing menuitem structure as static variable
+==================================================
+
+   In most case menuitems should be wrote as static variables. Because
+contents of this structure should change in future, please use one of
+macros defined in `xmenu.h'. They provides cleaner and easier to extend
+way to define this entries.
+
+   For example to define `MENU_NOPARAM' function use following macro:
+
+ - Function: MENUNOP (MENUNAME, KEY, NAME, SHORTNAME, FLAGS, FUNCTION)
+   Similar macros exist for the other types too. They ends for `CB' or
+`RB' for check-boxed or radio-boxes functions. See `menu.c' for large
+example of definitions. They should look like this:
+
+     static menuitem menuitems[] =   /*XaoS menu specifications */
+     {
+       SUBMENU ("", NULL, "Root menu", "root"),
+       SUBMENU ("", NULL, "Replay only commands", "plc"),
+       MENUNOP ("comm", NULL, "print menus specifications of all menus",
+                "print_menus", MENUFLAG_NOMENU|MENUFLAG_NOPLAY|MENUFLAG_ATSTARTUP,
+                uih_printallmenus),
+                ...
+
+Dialog description
+==================
+
+   Dialog description is similar to menuitem. It is array of following
+structures:
+     typedef struct dialog
+       {
+         char *question;
+         int type;
+         int defint;
+         char *defstr;
+         number_t deffloat;
+         number_t deffloat2;
+       }
+     menudialog;
+   It is terminated by QUESTION pointer set to `NULL'.
+
+   The QUESTION contains string ui should display when is asking for
+this field.
+
+   TYPE should be one of following values: `DIALOG_INT',
+`DIALOG_FLOAT', `DIALOG_STRING', `DIALOG_KEYSTRING' (the difference
+between string and keystring is, that in scripting language string is
+passed as `"hello"', but keystring is passed as scheme keyword as
+`'hello'), `DIALOG_IFILE' (input file), `DIALOG_OFILE', `DIALOG_CHOICE'
+(choice between different keystrings), `DIALOG_ONOFF' (boolean
+parameter), `DIALOG_COORD' (two floats--complex number)
+
+   Set to corresponding DEF* field for default value. In case of files
+use string in the format `"[PREFIX]*[EXTENSION]"'. For type
+`DIALOG_CHOICE' set DEFSTR to pointer to array of strings terminated by
+`NULL' entry.
+
+   To write dialog structures again use macros defined in `xmenu.h'
+like:
+     DIALOGSTR(question,default)
+   The definition should look like:
+
+     static menudialog uih_viewdialog[] =
+     {
+       DIALOGCOORD ("center:", 0, 0),
+       DIALOGFLOAT ("Radius:", 1),
+       DIALOGFLOAT ("Angle:", 0),
+       {NULL}
+     };
+
+Modifying registry
+==================
+
+ - Function: void menu_add (menuitem *ITEM, int N);
+     Add array of N items to the database.
+
+ - Function: void menu_delete (menuitem *ITEMS, int N);
+     Remove array of N items from database.
+
+Querying registry
+=================
+
+ - Function: menuitem* menu_findkey (char *KEY, char *ROOT);
+     Find item for given key. ROOT is menu where to start (submenus are
+     searched recursively)
+
+ - Function: menuitem* menu_findcommand (char *NAME);
+     Find item for given short name
+
+ - Function: char* menu_fullname (char *MENU);
+     Long name for the short name of menu
+
+ - Function: menuitem* menu_item (char *MENU, int N);
+     Nth entry of the MENU. Return `NULL' if no more entries available.
+
+ - Function: int menu_enabled (menuitem *ITEM, struct uih_context *C);
+     Check whether given item is activated (for check-boxed and
+     radio-boxed functions)
+
+ - Function: int menu_havedialog (menuitem *ITEM, struct uih_context
+          *C);
+     Does this function have dialog?
+
+ - Function: menu_getdialog (CONTEXT, M)
+     Macro returns pointer to dialog structure. (function must have it,
+     otherwise garbage is returned).
+
+ - Function: int menu_available (menuitem *ITEM, char *ROOT);
+     Check whether item is available as one of entries of ROOT (or it's
+     submenus)

+@chapter Overview of the XaoS design
+
+XaoS is divided into several ``libraries'' (some of them have been merged
+together; nonetheless the conceptual divisions are there and they can be
+separated easily).
+
+Understanding the design philosophy should help you to navigate in the sources.
+I also expect that much of the lower level stuff may be useful in other
+projects, since it is designed to be fairly generic.
+
+So here is an overview, from the lowest level stuff to the highest.
+
+@section Palette and image library
+
+@findex image
+@findex palette
+The sources for this are in the directory @code{src/filter}.
+The aim of the palette library is to provide a relatively abstract interface to
+the various visuals, and hide differences in the hardware and driver
+implementations. Fixed color, pseudocolor, grayscale and truecolor visuals
+should be handled in almost the same way.
+
+It provides the @code{palette} structure, containing a palette. You might
+allocate new colors here (you give an RGB value and the corresponding pixel
+is returned), interpolate colors where possible, cycle colors and so on.
+
+Every palette contains two parts --- the preallocated color cells and the actual
+palette. For instance, this could be used to allow the GUI the possibility to
+allocate static, unchanging colors for its texts and dialogs, while the rest of
+the palette is under the control of different parts of XaoS.
+
+This library also contains a set of functions to allocate different palettes
+used by other parts of XaOS. I expected that different parts of XaoS could share
+the same palette. This hasn't happened yet, but the functions are kept here just
+in case.
+
+The image library is built on top of the palette library, providing
+functionality for handling actual image data. Each image is represented by one
+or two frame-buffers (useful for double-buffering). One frame-buffer is
+called `current' and the other `old'. They are flipped by a special function.
+The program can draw into either of them.
+
+Frame-buffers are held as a set of pointers to scan-lines. This provides more
+flexibility than more obvious representations, because tricks like sub-windows
+and flipped bitmaps are possible. It's also fast, since you should avoid one
+multiplication.
+
+The last significant information the image structure holds is of course the bpp
+depth.  It is counted in bytes, and ranges from 0--4 (where 0 is used for 1bit
+bitmaps).
+
+@section Filter library
+Sources are available in @code{src/filter}.
+This library controls the process of image creation. It handles a queue of
+filters, where each filter modifies the image in some way. The filters at the
+beginning and end of the queue are special; the first filter is usually the
+actual fractal engine which creates the image, and the last filter is usually
+the user interface helper library.
+
+@section Xthread library
+This library provides an interface to various multi-threading libraries;
+currently the BeOS, plan9 and POSIX implementations are available. It allows the
+running of various functions in parallel, and provides some synchronization
+primitives (semaphores). It is simple, but has all the functionality required
+for the XaoS engine.
+
+@section Fractal library
+Sources are available in @code{src/engine/}, headers in @code{fractal.h}.
+This library contains the actual fractal calculation routines. It is governed by
+a fractal context, which contains information like the current formula, the seed
+(for julia sets), the palette, and so on.
+
+Functions for calculating the various fractal types and various coloring modes
+are also available here.
+
+@section Zooming engine and other filters.
+Sources are available in @code{src/engine/}.
+This is the actual zooming engine filter. It is fairly independent of the
+fractal library, so it could possibly be used for zooming other stuff. (It has
+already been used for zooming large scale images containing maps of Hungary).
+
+The file @code{ui_helper} contains the implementation of all filters not already
+mentioned, and a structure containing all functions exported from the filter to
+the user interface. One other terminal filter is implemented --- the Julia
+morpher. Other filters add special effects (such as motion blur), or do
+conversions (such as rotation or dithering).
+
+@section Timer library
+This library provides many useful timing primitives (such as timers).
+It is used by some other programs too.
+
+@section xio library
+This library aims to provide a unified, portable interface to the file
+system. Some strange systems (such as MacOS) have a very different filesystem
+API to UNIX; perhaps they don't represent filenames as a string, use special
+structures, or something; this library abstracts away from all that.
+
+@section xshl library
+Xshl stands for XaoS simple hypertext library. It contains a fairly universal
+engine parsing an `xshl' language, similar to HTML, with some additions and many
+restrictions. It can render text for both proportional and monospaced fonts, in
+various sizes.
+
+@section help library
+This is built on top of the xshl and xio libraries. It can read help files
+containing help chapters, can parse keywords in chapters, and so on.
+
+@section xmenu library
+This is the XaoS function registry. All functions from UI-Helper library are
+registered in the registry. From this registry the menus, dialogs, command
+line options and scripting language are built.
+
+@section Catalog library
+This is a library for handling message catalogs. It should read catalogs and
+convert keywords into an actual message.
+
+@section PNG library
+This library provides a function for saving an image from the Image library to a
+file, in PNG format. Other formats could be added as well if required.
+
+@section UI-helper library
+This library controls all the low-level stuff and provides a high-level
+interface to it. It has functions for playing animations, zooming/un-zooming
+and suchlike. It all the other libraries heavily. It doesn't implement
+functions for handling menus and such, but could be helpful for such
+implementations, because of the function registry database.
+
+@section Ugly interface
+This is currently the only real user interface for XaoS (there is another, wich
+is used for rendering animations, but it is not a user interface as users
+understand the term). It is built above the UI-helper library and provides
+functions for drawing menus, dialogs and so on.  It has drivers for many
+platforms, and can be easily ported to others.
+
+In the future, it should be quite easily extended to let drivers specify their
+own menu/dialog handling code; so it should be possible to give it a ``native''
+look on each platform.
+
+It can also operate in a mode where the GUI drawing routines are disabled; the
+function registry database is transferred through a pipe to an external program,
+which should build the menus and act as an external user interface, sending back
+commands in the scripting language (presumably representing things that the user
+has done). This provides another way to give a native look to the ugly interface,
+and could also be used to interface other scripting languages to XaoS.
+
+The ugly interface has one serious limitation --- for historical reasons, it is
+coded to handle just one window (the rest of XaoS can probably do multiple
+windows, but this is untested), so in windowed environments it is impossible to
+open multiple menus with fractals. On the other hand, this limitation is not so
+important once external GUIs enter the picture, as they could just start
+multiple XaoS engines. This is also preferred because it brings extra
+robustness, multitasking and some other advantages. That's why I don't plan to
+remove this limitation yet.
+

+@chapter Driver API description
+
+To port XaoS successfully to some platform you need:
+
+@itemize @bullet
+@item
+An ISO C compatible optimizing compiler. Note that an optimizing compiler is
+really required, since XaoS is coded to be a good target for optimizations and
+doesn't have many routines coded in assembly; so if you will use a bad compiler,
+you will notice drastic slowdowns (a slowdown of 10x or more). Some compilers
+have serious problems compiling XaoS; this applies to most DOS compilers (Watcom
+C, Borland C, Microsoft C) for instance.  They generate incorrect code or crash
+during compilation. I highly recommend using the GNU C compiler, but even some
+versions of GNU C have difficulty. Please read @code{compilers.txt} for more
+information.
+@item
+A fast way to avoid division by zero/overflow and other floating point
+exceptions. XaoS is carefully coded to not crash in this case, but doesn't have
+any tests to avoid such situations; expect random results in such cases.  Many
+platforms provide a means to switch coprocessor into a mode where 1/0 produces
+Inf and so on. If there is no such means, try to use some kind of signal handler
+that will ignore such exceptions.
+
+The ``normal'' solution --- add @code{if}s to avoid division by zero --- is
+almost impossible. Division is quite easy to check for, but other cases (such as
+overflows) are much harder. I don't think it is possible to avoid all crashes
+just by adding @code{if}s.
+
+XaoS doesn't depend on IEEE arithmetic. The result in the sort of edge cases
+where IEEE makes a difference is mostly undefined. XaoS usually works well with
+compiler switches for inexact math enabled (such as @code{-ffast-math} in GCC),
+but, of course, there are no guarantees. For example on Alphas this is not true,
+since they usually generate exceptions in that case.
+@item
+A text or graphics output device. If you only have a text output device you may
+use the AA driver, which renders fractals into high quality ASCII art. In this
+case you might want to skip this chapter, download AA-lib
+(http://www.ta.jcu.cz/aa) and read the porting chapter of AAlib manual. A
+graphics device must be one of:
+
+@findex C256
+@findex FIXEDCOLOR
+@findex GRAYSCALE
+@findex TRUECOLOR
+@findex TRUECOLOR24
+@findex TRUECOLOR32
+@itemize @bullet
+@item 8 bits per pixel with user definable palette @code{C256}, static palette @code{FIXEDCOLOR}, or static grayscale @code{GRAYSCALE}
+@item 16 bits per pixel with arbitrary bits per color @code{TRUECOLOR}
+@item 24 bits per pixel with 8 bits per color, arbitrary order @code{TRUECOLOR24}
+@item 32 bits per pixel with arbitrary order of colors, where each color fits in exactly one byte @code{TRUECOLOR}
+@item 1 bit per pixel bitmap, either least or most significant bit first
+@end itemize
+
+Please contact me if you have a different kind of device. Some modes (like
+mis-ordered truecolor modes) could be added really easily if required.  Note
+that mono/4/16 colors devices will probably never be supported internally by
+XaoS, since I expect they will be slower than 8bpp, so XaoS will internally work
+in 8bpp and then convert to 1/2/4bpp. Contact me if you want to write such a
+converter. (For bitmap one already exists --- see @code{dither.c}.)
+@item
+Some way to save images. By default XaoS uses @code{libpng}, which is ported to
+many platforms, but there are many platforms where it isn't ported yet. If your
+system has some standard image format which is easier to handle than
+@code{.png}, contact me and I will show you how to add such support to XaoS (see
+@code{png.c}).

+Stdio compatible library (this is a problem on the Mac and BeOS). XaoS has an
+abstract layer above stdio, so it can use other input/output libraries too. You
+could write another implementation of this layer, called @code{xio}. See
+@code{xio.h}, @code{xstdio.c}, and @code{xstdio_mac.h} for an example.
+@end itemize
+
+The ugly interface is designed to make writing new drivers as easy as possible.
+Use the file @code{ui_template} when starting to write a new driver from
+scratch. You need to write only a few functions, filling out the following
+table:
+@findex ui_driver
+@example
+struct ui_driver @{
+  char *name;
+  int (*init)(void);            /*initializing function. returns 0 if fail*/
+  void (*getsize)(int *,int *);	/*get current size..in full-screen versions
+                                  i.e svga and dos asks user for it*/
+  void (*processevents)(int,int *,int *,int *,int *);
+                                /*processevents..calls ui_resize,ui_key
+                                  also returns positions of mouse..
+                                  waits for event if first parameter is
+                                  1*/

+                                /*returns current mouse positions*/
+  void (*uninit)();             /*called before exit*/
+  int (*set_color)(int,int,int,int);
+                                /*alloc palette color and returns number*/

+  int flags;
+  float width,height;
+  int maxwidth,maxheight;

+  struct gui_driver gui_driver;
+@};
+@end example
+
+@section Functions
+
+@code{ui} uses the following functions to communicate with a driver:
+
+@defun init
+  Initializes the driver and returns 1 on success and 0 on failure.
+@end defun
+@defun getsize (int *@var{width}, int *@var{height})
+  Returns the size of screen (or window) in x and y dimensions.
+@end defun
+@defun processevents (int @var{wait}, int *@var{x},int *@var{y}, int *@var{buttonmask}, int &@var{keys})
+  Gets new keyboard/mouse events. Parameters are:
+  @table @var
+  @item wait
+     If 1, the function can block, waiting indefinitely for the next event,
+     otherwise it just determines if something's already arrived. This is
+     useful on multi-tasked OSes, where eating unnecessary CPU time on
+     busy-waiting is discouraged.
+  @item *x,*y
+    Returns the current mouse coordinates.
+  @item *b 
+    Returns a mouse button bitmask of @code{BUTTON1}, @code{BUTTON2}, and @code{BUTTON3}.
+  @item *k 
+    Returns a cursor key bitmask:
+    @table @code
+    @item 1 
+    @key{left}
+    @item 2 
+    @key{right}
+    @item 4 
+    @key{up}
+    @item 8 
+    @key{down}
+    @end table
+    @end table
+    The function calls @code{ui_key} (ASCII character) and @code{ui_resize}
+    if required. For special keys use @code{UIKEY_UP}, @code{UIKEY_DOWN}, etc.
+    See @code{ui.h} for a complete list of these constants.
+
+    In case of problems freeing/allocating inside @code{processevents} you may 
+    call @code{ui_call_resize}, which calls resize later outside this function.
+@end defun
+
+@defun uninit
+ Uninitialises driver---called before exit.
+@end defun
+
+@defun set_range (ui_palette *@var{palette}, int @var{start}, int @var{end})
+This is the preferred way to set the palette (the other way is with
+@code{set_color}). When @var{imagetype} is @code{UI_C256} (256 color with
+palette) one of these two functions @emph{must} be used. In truecolor modes they
+are unused. If direct palette access is possible on your platform, define this
+function. The function is expected to set all color cells between @var{start}
+and @var{end} to colors defined in @var{palette}. @var{ui_palette} is array of
+@var{ui_rgb} elements. @var{palette[0]} is the color of entry number
+@var{start}. @var{ui_rgb} is an array of @code{char}.  @var{palette[0][0]} is
+the red field of entry number @var{start}, @var{palette[0][1]} is the green and
+@var{palette[0][2]} is the blue. @code{0} means black and @code{255} means full
+intensity. Use @code{NULL} if your driver doesn't support this call.
+@end defun
+
+@defun set_color (int @var{r}, int @var{g}, int @var{b}, int @var{init})
+  This is a secondary way to set the palette, that should be used at platforms
+  w/o direct palette access (like X11 or static color schemes). It receives the
+  RGB value of the color, and returns the index of the color cell with this
+  color, or -1 if no more color cells are available. The @var{init} parameter is
+  set to 1 when this function is called for the first time on a given
+  palette; @code{set_color} is then expected to free all color entries
+  previously allocated. Use @code{NULL} if your driver doesn't support
+  this call.
+@end defun
+
+@defun print (int @var{x},int @var{y}, char *@var{text})
+  Prints text to screen at position x/y. This function is a bit archaic
+  (XaoS now uses its own functions drawing directly to the buffer in most
+  cases), but in some cases --- initialization messages or calculation ---
+  the functions are unusable, so we still need this primitive. In the
+  @code{C256} mode you can rely on the first allocated color always being
+  black and the second being white.
+@end defun
+
+@defun display (void)
+  Displays current buffer on screen
+@end defun
+
+@defun alloc_buffers (char **@var{buffer1},char **@var{buffer2})
+  Allocates two buffers that can hold a bitmap the size of the screen.
+  Also sets the current buffer to @var{buffer1}. Since version 2.1, this
+  returns the scan-line size in bytes (usually the screen width) or 0
+  on failure. This is useful on systems that allocate a bitmap bigger
+  than the window/screen (divisible by 4 or thereabouts).
+@end defun
+
+@defun free_buffers (char *@var{buffer1}, char *@var{buffer2})
+  Frees allocated buffers.
+@end defun
+
+@defun flip_buffer (void)
+  Flips buffers --- sets the current buffer to the other one.
+@end defun
+
+@defun flush (void)
+  This function should be used by drivers with buffered output to flush
+  those buffers. Other drivers should set it to @code{NULL}.
+@end defun
+
+@defun mousetype (int type)
+   This function is used to change the mouse cursor. @var{type} has the
+   following values:
+   @table @code
+   @item NORMALMOUSE
+     This pointer is that usually displayed, while the UI waits for user
+     input.
+   @item WAITMOUSE
+     This pointer is displayed when the UI is busy (perhaps the famous
+     hourglass) or you may use that defined in ui_dos --- a Mandelbrot
+     set.
+   @item REPLAYMOUSE
+     This pointer is displayed during replay. There should be none in
+     fullscreen drivers, since a blinking mouse cursor during replay
+     looks ugly. On windowed systems, disabling the mouse looks ugly,
+     so it should be some funny cursor.
+   @end table
+   You should use @code{NULL} if your driver doesn't support this.
+@end defun
+
+@section Other information
+Some additional variables are also used to inform the ui library about the
+driver. All these values can be changed by init functions in case they were
+unknown beforehand.
+
+@table @var
+@item textheight, textwidth
+  Width and height of your font
+@item palettestart, paletteend
+  First and last palette entry that can be changed. You should use this
+  to avoid changing entries reserved for the window system, UI objects,
+  mouse, etc.
+@item rmask, gmask, bmask
+  These fields are used in truecolor modes to specify where each color is
+  defined.
+@item maxentries;
+  Number of allocatable entries. Normally should be
+  @var{palettestart}-@var{paletteend}
+@item imagetype
+  Defines the type of image. Should be one of the following values:
+@findex UI_C256
+@findex UI_FIXEDCOLOR
+@findex UI_GRAYSCALE
+@findex UI_TRUECOLOR
+@findex UI_TRUECOLOR24
+@findex UI_TRUECOLOR32
+  @table @code
+  @item UI_C256
+    The classical 256 color with palette scheme used by most older graphics
+    adapters. You should also use it for static-color schemes, but they are
+    not well supported in current versions of XaoS.
+  @item UI_TRUECOLOR
+    32bpp truecolor mode
+  @item UI_TRUECOLOR24
+    24bpp truecolor mode
+  @item UI_TRUECOLOR16
+    16bpp truecolor mode
+  @end table
+@end table
+
+What follows is @emph{not required} to get the driver working at first,
+so you may skip to @emph{registering driver} on the first read and return
+here later.
+
+@table @var
+
+@item params
+  You may define command line options for your driver.
+
+  They are defined using a @var{params} structure like:
+@findex params
+  @example
+  static struct params params[]=@{
+    @{"-mode",P_NUMBER,&defmode,
+      "Select graphics mode(same number as in interactive menu)"@},
+    @{NULL,0,NULL,NULL@}  /*this MUST be last option field*/
+  @};
+  @end example
+
+  where every line is one parameter. The list ends with @code{@{NULL,0,NULL,NULL@}}.
+  The first field is the option name.
+  The second field is the parameter type:
+@findex P_SWITCH
+@findex P_NUMBER
+@findex P_STRING
+@findex P_FLOAT
+  @table @code
+    @item P_SWITCH 
+    No parameter --- variable is just set to 1 if the option is supplied.
+    @item P_NUMBER 
+    Integer number
+    @item P_STRING 
+    String
+    @item P_FLOAT 
+    Floating point number (variable is float)
+  @end table
+  The third element is a pointer to a variable that is changed if the option is
+  supplied. (For instance, it is @code{int*} for @code{P_NUMBER} or
+  @code{P_SWITCH}.)
+  The last element is help text displayed by @code{ui -h}.
+
+
+@item width,height
+  See @var{flags}. May be set to @code{0.0, 0.0} at the start.
+
+@item maxwidth,maxheight
+  See @var{flags}. May be set to 0,0 at the start.
+
+@item @var{flags}
+  This variable says more about your driver. A good starting value is 0.
+  But for the final version it is recommended to read the following carefully.
+
+  Flags are uppercase constants and should be set as follows:
+
+  @code{ASYNC_PALETTE | RANDOM_PALETTE_SIZE}
+
+  The following flag constants are supported:
+
+  @table @code
+@findex RANDOM_PALETTE_SIZE
+@findex UPDATE_AFTER_RESIZE
+@findex RESIZE_COMMAND
+  @item RANDOM_PALETTE_SIZE
+    States that the palette is randomly sized. This is used in X where the
+    palette is shared between many programs. By default XaoS allocates all
+    available colors up to 256. This is not very nice to other applications in
+    X, so this flag states that that a random number of colors (in the range
+    8--256) are allocated.
+  
+    When this variable is off XaoS expects that the same number of colors is
+    always available.
+  @item UPDATE_AFTER_RESIZE
+    Causes the screen to be recalculated and redrawn upon a resize, even if
+    its size has not changed, in case the resize procedure destroys data in
+    XaoS' buffers.
+  @item RESIZE_COMMAND
+    Some drivers (mainly the fullscreen ones) may ask the user for the size
+    and color depth to use, in the function @code{get_size}. It would be nice
+    to let the user change this parameter at runtime and force XaoS to
+    reinitialize all its images. This is done with the @code{ui_resize}
+    call
+
+    In windowed drivers, this is called by external window-system events, but in
+    fullscreen drivers you'll need a key or menu item for this. You could add
+    this function directly into XaoS's function registry (see for example the
+    GGI driver) --- it is useful mainly when you want to use a size selection
+    dialog that is standard for your environment, or let XaoS use its default
+    one. For example, see the SVGAlib or DOS driver.
+  @end table
+
+  Screen/window size information:
+
+    Xaos needs to know the exact physical size of displayed images. This is
+    required for random dot stereograms and also for keeping the aspect ratio
+    of fractals correct (do not make them wide in 640x200 resolution etc.)
+    At least one of the following values should be defined (given in the order I
+    prefer)
+@findex SCREENSIZE
+@findex PIXELSIZE
+@findex FULLSCREEN
+@findex RESOLUTION
+  @table @code
+    @item SCREENSIZE
+     The @var{width}/@var{height} values specify the exact size of the
+     screen/window in centimeters
+    @item PIXELSIZE
+     The @var{width}/@var{height} values specify the exact size of one pixel in
+     centimeters. This is better for windowed environments, where the window
+     size is often changed.
+    @item FULLSCREEN
+     The driver runs fullscreen. XaoS automatically uses the default screen size
+     (29.0cm x 21.5cm)
+    @item RESOLUTION
+     The driver does not know the exact screen size, but knows the resolution
+     used (in the @var{width}/@var{height} variables); XaoS automatically
+     calculates pixel width using width = 29.0cm/maxwidth and height =
+     21.5/maxheight.
+   @end table
+   Of course the default width and height can be changed by command line
+   options. You may also use combinations like:
+   
+   @table @code
+   @item SCREENSIZE | FULLSCREEN 
+   The best for fullscreen drivers
+   @item PIXELSIZE | RESOLUTION 
+   The best for windowed drivers
+   @item FULLSCREEN 
+   For fullscreen drivers that have no idea about screen size...  
+   @end table
+
+   Do not forget to set the @var{width}, @var{height}, @var{maxwidth},
+   @var{maxheight} fields if required.
+
+@item gui_driver
+   See the next section for description.
+@end table
+
+
+@section Registering the driver
+
+Once you've done the above, you just register the driver in @code{drivers.c} and
+you may compile :) You can use @code{ui_template.c} as a driver template.
+
+You may also look at the xthreads library description if you are porting XaoS to
+some SMP platform.
+
+Please let me know if you want to start to code a driver.
+
+@node gui-driver, eui ,driver ,Top
+@chapter Writing a GUI driver
+
+XaoS has a builtin GUI. Many operating systems have native GUI toolkits and XaoS
+default GUI might look strange there. To avoid this problem, you might write an
+external GUI program (see eui section) or write mappings from the XaoS GUI
+functions to the native ones. The advantage of an external GUI process is
+multitasking; XaoS is not thread safe and the GUI must be synchronous with
+calculation.  Also, the ugly interface code currently doesn't support multiple
+windows (although this should be solved in the future).  This solution is
+suitable mainly for those systems where two cooperating programs sharing one
+window is a problem (like Windows).
+
+To write a GUI driver you need to fill out the following structure:
+@example
+struct gui_driver
+@{
+   void (*setrootmenu)(struct uih_context *c, char *name);
+   void (*enabledisable)(struct uih_context *c, char *name);
+   void (*menu)(struct uih_context *c, char *name);
+   void (*dialog)(struct uih_context *c, char *name);
+   void (*help)(struct uih_context *c, char *name);
+@};
+@end example
+
+All functions have a @code{uih_context} parameter. You don't need to worry about
+its contents; just pass it to the functions that require it. This parameter is
+for multiple window support, which is not implemented yet.
+
+The @code{setrootmenu} function draws the root menu according to the menu called
+@code{name}. To get the menu fields you might use the following piece of code:
+@example
+#include <ui.h>
+#include <xmenu.h>
+
+....
+
+int i;
+menuitem *item;
+for (i = 0; (item = menu_item (name, i)) != NULL; i++)
+   @{
+      if (item->type == MENU_SUBMENU) @{
+	      /* This field is a submenu. You might call a function to
+	         construct the submenu here. item->shortname contains
+		 the name for the submenu.  */
+      @}
+      /* Add menu field here.
+
+         You might check flags here:
+         item->flags&MENUFLAG_CHECKBOX
+	   field has a checkbox
+         item->flags&MENUFLAG_RADIO
+	   field is part of a radio button group. In the current
+           implementation, there is one radio button group per menu.
+
+	 in both cases you can call menu_enabled(uih, item) to see
+	 if the item is checked or not.
+
+         item->name contains the field's text
+
+	 item->key contains a hotkey (a one letter string in the
+         current implementation)
+   @}
+@end example
+Once the field is selected, call the function @code{ui_menuactivate(item, NULL)}
+where @code{item} is a pointer to the @code{menuitem} record of the selected
+field.
+
+The @code{enabledisable} function is called when the checkbox or radiobutton
+state is changed. The @code{name} parameter is the same as the
+@code{item->shortname} of the changed field, so you need to search all the
+menus, compare @code{name} to @code{item->shortname}, and if it matches, call
+@code{menu_enabled} to get the new state. For radiobuttons, only enable events
+are noticed. Your code is expected to automatically disable all other
+radiobuttons in the same submenu.
+
+The @code{menu} function works similarly to @code{setrootmenu}, but displays a
+popup menu.
+
+The @code{dialog} function is called for dialogs. The function should look like:
+@example
+menuitem *item = menu_findcommand(name);
+menudialog *dialog = menu_getdialog(uih, item);
+int i;
+for(i=0; dialog[i].question; i++)
+@{
+   /* Construct dialog, where the left side contains labels with
+    dialog[i].question, and the right side contains input entities based on the
+    dialog[i].type. Dialog[i].type is one of the following:
+
+    DIALOG_INT: integer value input. The default value is: dialog[i].defint
+    DIALOG_FLOAT: floating point input value (long double, where available).
+    Default value is dialog: dialog[i].deffloat
+    DIALOG_COORD: complex value floating point input (two floats), default
+    values are dialog[i].deffloat and dialog[i].deffloat2
+    DIALOG_STRING: string input. Default value is dialog[i].defstr
+    DIALOG_IFILE: input file
+    DIALOG_OFILE: output file
+         default mask is dialog[i].defstr
+    DIALOG_CHOICE: choice between various strings.
+         cast dialog[i].defstr to char ** to get a pointer to a NULL
+         terminated array of choices.
+@}
+@end example
+Once the dialog is filled by the user, @code{gui_driver} is expected to allocate
+an array of union @code{dialogparam}:
+@example
+dialogparam *p = calloc (sizeof (*p), nitems);
+@end example
+and fill in the selected values. @code{p[i].dint} is used to pass an integer
+value, or the number of a DIALOG_CHOICE selection, @code{p[i].number} is used
+for floating point numbers, @code{p[i].dstring} for strings and filenames,
+@code{p[i].dcoord[0]} and @code{p[i].dcoord[1]} for complex values.
+
+The string values are expected to be in separately @code{malloc}ed chunks. Once
+the array is filled, call @code{ui_menuactivate(item, p)}.
+
+The function @code{help} is used to display help about a given topic. To
+implement it you could either convert XaoS help file to some native format, or
+use the xshl library to render the help page for you. To render an xshl page
+use:
+@example
+#include <xshl.h>
+xshl_line *lines;
+int getwidth (void *data, int flags, char *text)
+@{
+	return width of text with given flags
+	flags is mask of the following:
+         XSHL_BIG - large text
+         XSHL_EMPH - emphasized text
+         XSHL_MONOSPACE - monospaced text (typewriter)
+         XSHL_LINK - line (should be underlined or suchlike)
+         XSHL_WHITE 
+         XSHL_RED 
+         XSHL_BLACK - color of text (not very meaningful here)
+         XSHL_RIGHTALIGN 
+         XSHL_CENTERALIGN - alignment of text
+
+@}
+lines = help_make (name, getwidth, textheight, largetextheight);
+if (lines == NULL)
+  lines = help_make ("main", getwidth, textheight, largetextheight);
+
+@end example
+Now you might use @code{lines} to draw the help. It is a pointer to the array of
+structures:
+@example
+struct xshl_line @{
+  int y;
+  struct xshl_item *first;
+@};
+@end example
+@var{y} is the position of the line from the beginning of the text, and
+@var{first} is a pointer to the blocks of text on the line. The last line
+contains a @code{NULL} pointer in the first section.
+
+@code{first} is a linked list of @code{xshl_item} structures:
+@example
+struct xshl_item @{
+  struct xshl_context c;
+  char *text;
+  int x;
+  int width;
+  struct xshl_item *next;
+@};
+@end example
+
+You can draw @code{text} at position @code{x} (and @code{y} from the line
+record) using the text style described by @code{xshl_context}:
+@example
+struct xshl_context @{
+	  int flags;
+	  char *linktext;
+@};
+@end example
+@code{flags} has the same meaning as in the @code{getwidth}
+section. @code{linktext} is the name of the next help page when the field has
+the @code{XSHL_LINK} atribute.
+
+For an example of @code{gui_driver}, see the win32 driver code.

+@node eui, ui-helper ,gui-driver ,Top
+@chapter Writing an external user interface
+
+This part describes how to make an external user interface --- that is, a
+separate program which constructs a window with all menus and dialogs. It uses
+the XaoS engine to calculate the fractal as a separate process. This design
+brings many advantages --- the external GUI implementation could have a ``native
+look'' for given platform and could contain many extensions (perhaps multiple
+windows). Also all calculation is done while multitasking, so the user interface
+is usable even when the engine is busy.
+
+The X Window System provides a way for programs to draw into others' windows ---
+the ``master'' program creates window the sub-window where it wants to put the
+fractal, then calls the engine with @code{-windowid} @var{number_of_window}
+parameters. Instead of creating a new window, the engine uses uses the specified
+window. The most famous example of such cooperation is probably
+ghostscript/ghostview.
+
+Other windowed environments probably provide similar means for for
+cooperation. In most others it will probably be implemented using shared memory,
+so it should work on most platforms, I expect.
+
+Of course, you might also design the UI as a separate button box in another
+window, like most animation players, or ImageMagick do. In fact, the external
+GUI could be very similar in style to ImageMagick...
+
+@section Basic concept
+
+The UI implementation has a function to disable its GUI functions.  Because of
+the function registry, all its menus and dialogs are described in a fairly
+simple database, which is also mapped to the Scheme-like scripting language.
+The external UI implementation can just translate the user's actions into this
+scripting language and send that through the pipe.
+
+The commands, menus, and dialogs should be created automatically from the
+database, so the UI doesn't need to have special code for each XaoS feature. At
+the beginning it should use XaoS' @code{(print_menus)} command to force it to
+send information about the database, then build menus using this information.
+
+For this you only need some equivalent to UNIX pipes, so again I expect it is
+doable on most platforms.
+
+@section Starting XaoS as a slave process
+
+One of the first things the engine needs to do is to initialize XaoS in the
+right mode to work as a slave process. For this you need to do several things:
+
+
+@itemize @bullet
+@item Open the pipe
+@item Disable the builtin GUI
+@item Read the menu hierarchy (this is optional --- GUI can also have all menus
+coded into it. But it is not recommended, since it will cause problems with
+adding new features in future)
+@end itemize
+
+Opening pipe is done via the @code{-pipe} option. It takes one parameter, the
+name of the FIFO you want to use. If you specify ``@code{-}'', XaoS will read
+input from stdin.
+
+To disable the XaoS GUI use @code{-nogui}. This will disable all menus, dialogs
+and help text.
+
+To read the menu hierarchy, just add @code{-print_menus} parameter and then
+parse XaoS's output. This will print the whole menu hierarchy. If you are
+building menus at the time they are selected, you might prefer to use the
+@code{print_menu} command, which prints just one menu without its submenus; its
+output could be immediately used for building a menu. The command takes one
+string parameter, the name the menu you want to print; i.e., to print the root
+menu use @code{-print_menu root}.
+
+Under the X Window System you also need to specify the @code{-windowid}; also
+the @code{-shared} option is quite recommended. Otherwise in pseudocolor visuals
+XaoS will create its own colormap, wich will likely collide with the UI's
+colormap, and either XaoS or the UI will have wrong colors. If you have any
+idea how to avoid this, let me know.
+
+You might also let the user specify some extra parameters from the command line,
+by simply adding those options to the end of the command line. The @code{-nogui}
+and @code{-print_menus} commands must be first for a simple reason: XaoS parses
+its command line early in initialization. Some commands (like
+@code{-print_menus}) should be processed at this time, while others (like
+@code{-loadpos} need a working engine. Such commands are queued and processed
+later, once the engine is initialized. XaoS never reorders commands; if an
+option that requires queuing is located before @code{-print_menus} on the
+command line, it will queue @code{-print_menus} too. This will cause the menus
+to be printed much later, slowing startup.
+
+So the proper calling sequence for the user interface under X should look like:
+
+
+@example
+xaos -nogui -print_menus -windowid <id> -share -pipe - @var{[other options]}
+@end example
+
+@section Parsing the menu structure
+
+The structure is printed menu by menu. Each menu contains a header, some
+entries, then @code{endmenu}. The listing from @code{print_menus} is terminated
+by @code{endmenus}.
+
+The header starts with @code{menu} and then contains a menu identifier, and the
+menu's full name, e.g.
+
+@example
+menu "fractal" "Fractal"
+@end example
+
+Each entry which follows has its own line. It starts with a menu type, which
+should be @code{submenu} or @code{menuentry}.
+
+@code{submenu} has a similar format to the header --- the full menu name, and an
+identifier.
+
+The next few fields are @code{menuentry}-related. It has an entry type, which
+could be @code{normal}, @code{radio} or @code{checkbox}. @code{radio} and
+@code{checkbox} are followed by @code{on} or @code{off} specifying whether it is
+enabled or disabled by default. (The radio-buttons don't have explicit
+information about which group they belong to. For now I expect that each menu
+contains just one such group, so it is clear in any case.)
+
+A set of flags should follow. Currently two flags are defined: @code{dialog},
+wich specifies that the function has a dialog box, and
+@code{dialogatdisable}. By default, dialogs for check-boxed functions are
+displayed only when the checkboxes are enabled. The second flag reverses this
+behaviour. It is currently used for the @code{mandelbrot} function, which
+behaves in this way; when you disable it, the user is prompted for the Julia
+seed.
+
+So a specification should look something like this:
+
+@example
+menu fractal "Fractal"
+submenu "formulae" "mformula"
+submenu "Incoloring mode" "mincoloring"
+submenu "Outcoloring mode" "moutcoloring"
+submenu "Plane" "mplane"
+submenu "Palette" "palette"
+menuentry "Mandelbrot mode" "uimandelbrot" checkbox off dialogatdisable dialog
+menuentry "Perturbation" "uiperturbation" checkbox off dialog
+menuentry "View" "uiview" normal dialog
+menuentry "Reset to defaults" "initstate" normal
+endmenu
+@end example
+
+@section Activating functions and dialogs
+
+Once the menu structure is built and the user selects some item, it should be
+activated. This is done by a simple command: @code{(@var{name})}. Once
+``@code{)}'' is sent, the command is executed by XaoS.
+
+Check-boxed functions has one extra parameter --- @code{#t} to enable them and
+@code{#f} to disable. So if you want to enable the @code{autopilot} item, send:
+@code{autopilot #t}
+
+Radio-buttons don't have any such parameter, because disabling radio-buttons
+makes no sense.
+
+If the item has a dialog enabled, the engine expects that the UI will make the
+dialog first, ask the user for values and then pass back a function with
+parameters. But first, the UI needs to know what parameters the function
+expects.  This is done by sending the command @code{(print_dialog
+"@var{name}")}.  XaoS replies with a dialog specification very similar to the
+menu specification.
+
+This has the header @code{dialog} followed by the name of the function being
+described. Then one dialog entry per line is sent, started by
+@code{dialogentry}, followed by the question the UI should display. Next is a
+type, which should be one of the following:
+@table @code
+@item integer
+Integer number such as @code{123}
+@item float
+Floating point number such as @code{123.123}
+@item string
+String such as @code{"ahoj"}
+@item keyword
+String such as @code{'ahoj}. Keywords are mostly similar to strings, except that
+they can not contain spaces. They are used, for example, for specifying types of
+formulae. Strings are used for printing text and so on.
+@item inputfile
+@item outputfile
+Here the UI should display a file selection dialogs. With @code{outputfile} it
+is also a good idea to check whether the file exists and ask the user if he
+wants to overwrite it.
+@item onoff
+Boolean value (@code{#f}, or @code{#t})
+@item complex
+Complex value --- two floating point numbers such as @code{123.123 123.123}
+@item choice
+Choice between some keywords. The keywords are sent after @code{choice},
+enclosed in @code{@{} @code{@}}.
+@end table
+The last information on the line is the default value, in the same format as the
+examples above. For files, the default value is in the format
+@code{"@var{[prefix]}*@var{[extension]}"}.
+
+Some examples:
+
+@example
+customdialog "uiview"
+dialogentry "center:" complex 0.000000 0.000000
+dialogentry "Radius:" float 0.000000
+dialogentry "Angle:" float 0.000000
+enddialog
+
+dialog "load"
+dialogentry "Filename:" inputfile "fract*.xpf"
+enddialog
+
+customdialog "color"
+dialogentry "Color" choice @{white black red @}white
+enddialog
+
+@end example
+
+To activate a function, send a command consisting of the function name followed
+by a sequence of parameters, mapped one-to-one to dialog box fields, in the same
+order as those fields. The parameters have the same format as in the above
+examples; checkbox fields return @code{#t} and @code{#f}. For instance:
+
+@example
+(uiview 0 0 0.5 0)
+(load "text.xpf")
+(color 'white)
+@end example
+
+@section Synchronization
+
+In some cases, XaoS can change radio-box and check-box values itself (when user
+presses a key, or loads some file, for instance). All such changes are sent to
+the GUI so that it can update what the user sees correspondingly. They are sent
+to standard output in the following format:
+
+@example
+checkbox "name" on/off
+radio "name" on/off
+@end example
+
+Your GUI code should parse this and change its menus when necessary.
+
+XaoS's menus can contain multiple distinct trees. In some cases (like when
+animation replay is active) the root of the menu structure should change. To
+indicate this to the GUI, XaoS sends a command:
+
+@example
+root "name"
+@end example
+
+Also, the user can press keys which normally display menus, dialogs or
+help. If XaoS has the keyboard focus, it will receive these instead of the
+GUI. XaoS sends commands to indicate this:
+
+@example
+menu "name"
+dialog "name"
+help "topic"
+@end example
+
+All these commands should be taken into account by the GUI, or could be ignored
+(not recommended!)
+
+@section help
+
+XaoS's help is in a simple hypertext language. In order to simplify its parsing,
+I've made xshl and help libraries. Making a help window with these libraries
+should be quite easy; just call the help function:
+@deftypefn Function struct xshl_line *help_make (char *@var{command}, int @var{getwidth} (void *, int @var{flags}, char *@var{text}), int @var{width}, int @var{smallheight}, int @var{bigheight});
+@end deftypefn
+and you will receive a stream of text with coordinates describing where to
+display the text into the shared window.
+
+The @code{command} parameter is the help topic. The @code{getwidth} function
+returns the width of a given piece of text. @code{width} is the width of the
+window, @code{smallheight} is the height of the small font, and @code{bigheight}
+is the height of the big font.
+
+Please ask me for more details if necessary.
+
+And thats all. Good luck with coding.

+@chapter UI-helper library
+
+UI helper library takes care of all of XaoS' engine functions and features and
+provides a higher level API which is quite easy to understand. If you want to
+write a completely new user interface (a replacement for the ugly interface ---
+not just new bindings for native menus or external user interfaces) or you want
+to use the XaoS engine in your program, you will probably want to use this
+library.
+
+Its API has many calls and features. This section gives a brief overview of its
+calls. Please ask me for details.
+
+@section initialization
+
+To initialize the UI helper library, you need to prepare a palette and image.
+The palette is created using the palette library call
+@code{createpalette}. Creating a truecolor palette should look like this:
+
+@example
+  struct palette *pal = createpalette (0, 0, TRUECOLOR, 0, 0, NULL,
+                                       NULL, NULL, NULL);
+@end example
+
+For details about creating palettes see @code{ui.c} or ask me.
+
+To create an image, call:
+
+@example
+  struct *image img = create_image_mem (width, height, 2, pal,
+                                        pixelwidth, pixelheight);
+@end example
+
+This creates an image in memory. If you want to create it in your own buffers,
+you might use @code{create_image_cont} or @code{create_image} calls.  Again see
+@code{ui.c}.
+
+Then it is time to fire up the main library:
+
+@example
+  struct uih_context *uih = uih_mkcontext (0, img, passfunc,
+                                           NULL, NULL);
+@end example
+
+The @code{passfunc} is called when the engine is calculating. It might process
+external events and display progress information. It should look like this:
+
+@example
+static int
+ui_passfunc (struct uih_context *c, int display, char *text, float percent)
+@{
+  /*process events */
+  if (uih->display)
+    @{
+      uih_drawwindows (uih);
+      /*display */
+    @}
+  if (display)
+    @{
+      if (percent)
+	sprintf (str, "%s %3.2f%%        ", text, (double) percent);
+      else
+	sprintf (str, "%s          ", text);
+      /*display it */
+    @}
+@}
+@end example
+It can set @code{uih->interrupt} if it wants to interrupt the current
+calculation (whereupon the main calculation loop will return to its caller).
+
+You can also load the catalog file in order to make tutorials work:
+
+@example
+  uih_loadcatalog (uih, "english");
+@end example
+
+Once this is done, the ui_helper library is fully functional and you can enter
+the main loop.
+
+@section main loop
+The UI helper library does not have any timing primitives; so it expects a
+standard form of main loop. It asks it caller to redisplay a changed image when
+necessary.  The library also uses the generic timerlib library for its timing,
+for which see elsewhere in this document.
+
+The main loop should look like this:
+
+@example
+while (1)
+  @{
+    if (uih->display)
+      @{
+	uih_prepare_image (uih);
+	uih_drawwindows(uih);
+	/*display current image buffer*/
+      @}
+    uih_update (uih, mousex, mousey, buttons);
+    if ((time = tl_process_group (syncgroup, NULL)) != -1 &&
+	    !uih->inanimation) @{
+	    /*relax for the given time in usec - wait for events etc..*/
+    @}
+    /*and repeat*/
+  @}
+@end example
+
+@section Calling functions
+
+The UI helper library has many functions declared in @code{ui_helper.h} for
+various actions. There are too many of them to describe here, but their names
+are quite informative, so I hope you will not have problems.
+
+(You could also use the XaoS function registry, which does all this stuff for
+you; you will just draw menus and dialogs based on this registry and all
+features will be automatically made available. If you are writing an ordinary
+user interface, this is the preferred way.)
+
+Note that the @code{ui_helper} library is not reentrant, so you can't call most
+of these functions from the @code{passfunc}. If you are using the registry, the
+activating function handles this automatically and queues functions when
+necessary.  To process them you need to flush the queue in the main loop as
+follows:
+
+@example
+static void
+processbuffer (void)
+@{
+  menuitem *item;
+  dialogparam *d;
+  if (uih->incalculation)
+    return;
+  while ((item = menu_delqueue (&d)) != NULL)
+    @{
+      menu_menuactivate (item, d);
+    @}
+@}
+@end example
+
+@section closing library
+
+This is done using: 
+
+@example
+  uih_freecontext (uih);
+@end example
+
+One user of this library is the ugly interface code in XaoS; see the
+@code{src/ui} directory. Another, much simpler user is
+@code{src/ui-hlp/render.c}, which does animation rendering.
+
+@node xthreads, filters ,ui-helper ,Top
+@chapter XaoS thread library
+
+This description should be useful for those who want to port XaoS to
+multiprocessor platforms, and those who want to implement a filter or other
+relatively computationally expensive code. Note that the thread library uses
+nothread calls as a degenerate case when only one thread is used, when the host
+does not allow multi-threading or it is not an SMP architecture (since this
+library is used only to distribute calculation into other CPUs).
+
+XaoS thread library is a simple map of a few functions required by XaoS to the
+system's library for threads.
+
+It has the following variables:
+
+@deffn Variable ethreads
+This is set to 1 in the case that threads are enabled
+@end deffn
+
+@deffn Variable nthreads
+Number of threads
+@end deffn
+
+It provides the following functions:
+
+@deftypefn Function {void} xth_init (int @var{threads})
+This function initializes the threading library (starts threads, sets
+@var{ethread} to @code{1} and @var{nthreads} to @var{n}. @var{threads} parameter
+should be set to 0 for auto-detection, or to the number of threads the user
+wants. If threads is set to 1, the threading library is disabled and the
+following functions are mapped to the @code{nothread_} equivalents defined in
+@code{xthread.h}.
+
+Note that all threads are not interchangeable --- there is a main thread (the
+one that called @code{xth_init}) that communicates with drivers, controls
+calculation, and so on, and there are child threads that are waiting for orders
+from the main thread. The latter threads can't use any functions from the
+xthread library.
+@end deftypefn
+
+@deftypefn Function {void} xth_uninit (void)
+This function un-initializes the thread library --- kills child threads and sets
+@var{ethread} to 0 and @var{nthreads} to 1.
+@end deftypefn
+
+@deftypefn Function {void} xth_function (xfunction *@var{function}, void *data, int @var{range})
+This function is used when the engine wants to perform some operation on the
+image in parallel. It is expected to wait until all threads are ready, then
+start @var{function} on all threads, including the control one, with the
+following parameters: @var{data} --- the same as @var{data} passed to
+@code{xth_function}, @var{taskinfo} --- pointer to a platform-dependent
+@code{taskinfo} structure (defined in @code{xthread.h}), but must have at least
+a field @code{n}, that holds the thread number (where the control thread is
+numbered 0 and other threads are numbered in the range 1 -- @var{nthreads}).
+The next two parameters are the range of images across which the function is
+expected to work. @code{xth_function} is expected to divide @var{range} into
+@var{nthreads} equal pieces and pass to each thread the start of a piece and the
+start of the next piece (@var{range} for the last one). The function does not
+wait for other threads to finish at the end, but returns immediately to main
+thread after @var{function} returns.
+
+This function is called approx. 5--10 times per frame.
+@end deftypefn
+
+@deftypefn Function {void} xth_sync (void)
+This function waits until all threads are ready for the next order from the main
+task.
+
+This function is called approx 5--10 times per frame.
+@end deftypefn
+
+@deftypefn Function {void} xth_bgjob (xfunction *@var{function}, void *@var{data})
+This function is expected to behave as follows: if there are any threads waiting
+for orders, ask one of them to call @var{function} with similar conventions as
+in @code{xth_function} except that the @var{range} parameters are set to 0.
+Otherwise it starts function in the foreground, as usual.
+
+This function is called once per frame.
+@end deftypefn
+
+@deftypefn Function {void} xth_nthread (struct taskinfo *@var{s})
+This function should be used to determine the current thread number. Do not use
+@code{taskinfo->n} instead, since if threads are disabled this will be defined
+to 0 to allow the optimizer to perform better optimizations.  This function can
+be called by all threads.
+@end deftypefn
+
+@deftypefn Function {void} xth_lock (int @var{n})
+@end deftypefn
+@deftypefn Function {void} xth_unlock (int @var{n})
+Lock/unlock lock number @var{n}. At least @code{MAXSEMAPHORS} locks must be
+available.
+@findex MAXSEMAPHORS
+
+Note that locks are used for very short fragments of code, so they need to be
+fast; so spinlocks may be better than classical Dijkstra semaphores (although
+this is untested). They are called once per calculated line/row during zoom and
+once per approx 10 pixels during calculation of a new image.
+@end deftypefn
+
+@findex MAXCONDS
+@deftypefn Function {void} xth_sleep (int @var{n}, int @var{l})
+Expected to atomically unlock lock @var{l} and sleep in queue @var{n}.  At least
+@code{MAXCONDS} queues must be available.  After the function is woken up, lock
+@var{l} again. This mechanism is used by the new image calculation algorithm,
+but it is designed to minimize its calls, so I expect it should be called once
+or twice.
+@end deftypefn
+
+@deftypefn Function {void} xth_wakeup (int @var{n})
+Wake up some thread from queue @var{n}. The lock used by sleep calls is locked
+in this case. The function should wake up all threads if a single-thread awaken
+is not supported by the host API.
+
+With luck, this function will not be called at all; it will be called by the new
+image calculation routines when the queue is empty. This happens when there are
+50 threads or thereabouts, but happens rarely at two or eight threads in my
+tests.
+@end deftypefn
+
+@deftypefn Function {void} xth_wakeall (int @var{n})
+Similar to wakeup but wake up all threads.
+@end deftypefn
+

+@chapter Filters
+
+This is a brief description of the filter system used internally by XaoS.
+Filters in XaoS provide an object oriented interface to every part of the XaoS
+engine. The main filters are the user interface implemented in ui_helper.c and
+the zooming engine implemented in zoom.c. Active filters are kept in a queue ---
+in the beginnning there are just two filters here (zoom and ui), but at any
+later time additional filters (stereogram generation, and so on) can be inserted
+into the middle of the queue.
+
+When calculating, every filter should use data calculated by the filter
+immediately before it in the queue, which that filter placed into the image it
+passes to its child.  For example, the stereogram filter should take the fractal
+generated by the zooming engine and create a stereogram from it (assuming that
+the zooming engine is immediately after the zooming engine in the filter queue).
+
+This makes XaoS's code more flexible and makes future enhancements easy (perhaps
+a different zooming engine, or image rotation, other special effects, plug-ins
+or some other funny stuff) since the enhancements are forced to be decoupled by
+the filter library, and since each filter has a degree of control over filters
+that follow it in the queue.  For instance, the stereogram filter should change
+the palette, force the zooming engine to change the depth, width and height of
+the calculated image to fit its needs, and so on.
+
+This document mainly describes the creation of a filter like the stereogram
+generator --- i.e. a filter placed into the middle of the queue --- since I
+don't expect there will be many people creating ``terminal'' filters (zooming
+engines/user interface layers). Note that different user interfaces are
+possible, since the user interface layer is not the real user interface, just a
+set of high level functions that should be called by the main application, like
+@code{set_view}. So if you want to use XaoS as a calculation engine in your
+program this document is probably not for you.
+
+Each filter is defined by a @var{filteraction} structure, as follows::
+@findex filteraction
+@example
+struct filteraction @{
+  char *name;
+  char *shortname;
+  int flags;
+  struct filter *(*getinstance)(struct filteraction *a);
+  void (*destroyinstance)(struct filter *f);
+  int (*doit)(struct filter *f,int flags,int time);
+  int (*requirement)(struct filter *f,struct requirements *r);
+  int (*initialize)(struct filter *f,struct initdata *i);
+  void (*convertup)(struct filter *f,int *x,int *y);
+  void (*convertdown)(struct filter *f,int *x,int *y);
+  void (*removefilter)(struct filter *f);
+@};
+@end example
+This structure describes unchanging parameters to the filter (like its name) and
+a basic set of methods required for communication with the rest of XaoS.  The
+@var{name} field is a comparatively long description of the filter's name, such
+as ``A random dot stereogram generator''. @var{name} is displayed by the ugly
+interface in the Filters menu, so it is expected to be descriptive (but shorter
+than 30 characters). The short name is a one word long name for the filter, like
+``stereogram''. This name is used in save files and command line parameters;
+everywhere that the user might need to write it, so writing a long descriptive
+name would just be wasteful of time and disk space.
+
+The flags field is reserved for future enhancements and is expected to be 0 for
+now.
+
+@section Instance creation / destruction
+
+Functions @code{getinstance} and @code{destroyinstance} are equivalent to the
+constructor and destructor in object-oriented languages. @code{getinstance} is
+expected to create and fill out the following structure:
+
+@findex filter
+@example
+struct filter @{
+  struct filter *next,*previous;
+  struct queue *queue;
+  struct filteraction *action;
+  struct image *image,*childimage;
+  struct requirements req;
+  struct fractal_context *fractalc;
+  void *data;
+  char *name;
+  int flags;
+  void (*wait_function) (struct filter *f);
+  /*stuff for wait_function*/
+  int pos,max,incalculation,readyforinterrupt,interrupt;
+  char *pass;
+@};
+@end example
+Although this structure seems to be long and complex, most of the fields are
+currently unused, and the rest of them are filled out automatically by a helper
+function:
+
+@deftypefn Function {struct filter *} createfilter (struct filteraction *@var{fa});
+
+This function should be used to do the dirty work of instance creation and fill
+out the @var{filter} structure. The only possibly interesting field is
+@var{data}, a pointer reserved for the filter's internal use; it can be a
+pointer to the filter's internal variables if required. This is what a
+@code{getinstance} implementation that allocates such an additional structure
+might look like:
+
+@findex getinstance
+@example
+static struct filter *getinstance(struct filteraction *a)
+@{
+      struct filter *f = createfilter(a);    /*create filter structure*/
+      struct stereogramdata *i=calloc(sizeof(*i),1);
+                                             /*allocate internal variables*/
+      /*initialize your variables here*/
+      f->data=i;                             /*add pointer to internal data*/
+      return (f);
+@}
+@end example
+
+If nothing similar is required you can simply put @code{creatfilter} into the
+@var{getinstance} field.
+
+@end deftypefn
+
+@code{destroyinstance} is expected to free the memory used by the filter
+structure and all the filter's internal data. To free the filter structure use
+the normal @code{free} call. An implementation of such function should look
+something like
+:
+@example
+static void destroyinstance(struct filter *f)
+@{
+     destroyinheredimage(f);
+     free(f->data);
+     free(f);
+@}
+@end example
+The meaning of @code{destroyinheredimage} will be described later.
+
+
+@section Initialization
+
+During the initialization phase, each filter says to its parent what kind of
+images it supports (which should depend on the images that it's child has said
+it supported), the parent chooses the best supported image format for its
+purpose and gives that to the child (while passing that information on up the
+queue of filters). Initialization is done in two passes:
+
+The first pass starts at the lowest filter in the queue (zoom, by default); each
+filter passes a @var{requirements} structure to its parent.
+
+The second pass starts at the highest filter (the ui filter), and each filter
+passes to its child an image and some other stuff. Then calculation should
+begin.
+
+The queue needs to be reinitialized after creating, resizing, adding or removing
+a filter, and similar operations.
+
+The first pass is implemented using the @code{require} function. This function
+is expected to look at the child's requirements it received as a parameter, fill
+out its own @var{requirements} structure, and call the @code{require} function
+of its parent filter.
+@findex requirements
+@example
+struct requirements @{
+  int nimages;
+  int supportedmask;
+  int flags;
+@};
+@end example
+The @var{nimages} field should be set to 1 or 2. When it is 2, the parent filter
+@emph{must} pass the image in two buffers (double-buffered). Note that if it is
+1, the parent @emph{should} pass the image in two buffers, but is not required
+to.
+
+@var{supportedmask} is a mask giving the image types supported by the
+filter. Valid image types are:
+@findex C256
+@findex FIXEDCOLOR
+@findex GRAYSCALE
+@findex TRUECOLOR
+@findex TRUECOLOR24
+@findex TRUECOLOR32
+@table @code
+@item C256
+  A normal 8bpp image with palette
+@item TRUECOLOR24
+  A 24bpp truecolor image with 8 bits for each color.
+@item TRUECOLOR16
+  A 16bpp truecolor image
+@item TRUECOLOR
+  A 32bpp truecolor image with 8 bits for each color.
+@item LARGEITER
+  A 16bpp image, but without colors. The pixels are expected to hold an
+  iteration count; it could also be thought of as a 16bpp grayscale image.
+@item SMALLITER
+  Similar to @code{LARGEITER}, but 8bpp.
+@end table
+
+@findex MASK1BPP
+If you don't want to worry about palettes, color allocations and so on, but just
+want to do some non-display operation with a bitmap, you probably only care
+about the image depth and not the precise meaning of the pixels; in that case,
+you can use one of the bitmasks @code{MASK1BPP} for 8 bit images,
+@code{MASK2BPP} for 16 bit and so on.
+
+The final field in the @var{requirements} structure is @var{flags}. It's a mask
+composed from the following constants:
+
+@table @code
+@item IMAGEDATA
+  Set this if your filter requires the data from previous frame untouched. When
+  this is not set, filters can reuse your image and change it. But some
+  filters, like motion blur or the zooming engine, require data from the
+  previous frame to construct the new one; for such filters, this flag should be
+  set.
+@end table
+There are no more flags supported at the moment. The @code{require} function
+should also save the child's @code{requirements} structure into
+@var{filter->req} for later use by the initialize pass. The code for a
+@code{requirement} function might look like
+@example
+static int requirement(struct filter *f,struct requirements *r)
+@{
+  f->req=*r;    /*Save an child's requirements*/
+  r->nimages=1; /*Just one image is required*/
+  r->flags&=~IMAGEDATA;/*unset the imagedata field*/
+  r->supportedmask=C256|TRUECOLOR|HICOLOR|REALCOLOR;
+                /*mask of all supported image types*/
+  return (f->next->action->requirement(f->next, r));
+                /*call parent*/
+@}
+@end example
+The next pass is the main initialization pass. It goes in the opposite order
+(from parent to child, from the top of the queue to the bottom, in the same
+direction as image flow), and the child receives some stuff from the parent
+(such as images). The @code{initialize} function receives an @var{initdata}
+structure:
+@findex initdata
+@example
+struct initdata @{
+  void (*wait_function) (struct filter *f);
+  struct image *image;
+  struct fractal_context *fractalc;
+  int flags;
+@};
+@end example
+@var{wait_function} points to a function called by the filter during calculation
+that lets the parent filter (usually the user interface layer) inform the user
+of calculation progress. @var{image} is an image expected to be filled with an
+image in the calculation phase. @var{fractalc} is a pointer to a structure that
+will contain information about the fractal itself during calculation (formula
+type and so on). @var{flags} is a mask of the following constants:
+@table @code
+@item DATALOST
+ This is set if the data in the previous image was lost (if the image was
+ cleared or resized or freshly allocated). Filters that use data from previous
+ frames should pay attention to this flag. The zooming engine, for example,
+ recalculates the whole image if this flag is set, since all pixels from
+ the previous frame were lost.
+ Note that data will also be lost if the filter receives a different
+ @var{image} than in the previous initialization (since some filter before it in
+ the queue was removed).
+@end table
+Inheritance is carried out using these functions:
+
+@deftypefn Function void inhermisc (struct filter *@var{f},struct initdata *@var{i});
+
+This function sets fields in the filter structure like @var{fractalc} or
+@var{wait_func}.  Inheritance of images is quite complex, since the new image
+needs to be prepared for the child filter. In order to save memory it is highly
+recommended to use the same image --- or at least the same memory --- for data
+when passing to the child, but this is not allays possible. The following
+function implements a heuristic to reuse the image where possible:
+@end deftypefn
+@deftypefn Function int inherimage (struct filter *@var{f},struct initdata *@var{data}, int @var{flags}, int @var{width}, int @var{height}, struct palette *@var{palette}, float @var{pixelwidth}, float @var{pixelheight}) 
+You should call this function in your @code{initialize} pass. It fills out
+@var{image} and @var{childimage} in the @var{filter} structure, and prepares
+@var{initdata} and @var{image} for the child. Note that in some cases it may
+fail and return 0. In this case the filter is expected to interrupt
+initialization and return 0 too.
+
+The @var{flags} parameter is a mask of the following constants:
+@table @code
+@item IMAGEDATA
+  Set if your filter requires data from the previous frame.
+@item TOUCHDATA
+  Set if your filter touches data in the output image. This is the usual case,
+  but some filters, like interlace or subwindow, don't touch the image data at
+  all.
+@item NEWIMAGE
+  Set if your filter cannot use the same image for output as it uses for input
+  (that is, if the two images must be distinct blocks of memory).
+@end table
+@var{width} and @var{height} are the width and height of the image you want to
+pass to the child; it should be set to 0 if you want the same width/height as in
+the parent image. @var{palette} is the palette of the image you want to pass;
+set to @code{NULL} if the palette should be inherited from the parent's image
+(as is usual).  @var{pixelwidth} and @var{pixelheight} give the physical size of
+a pixel in centimeters; if set to 0 they are inherit from the parent's image.
+@end deftypefn
+
+If you use the @code{inherimage} mechanism, you must also call
+@code{destroyinheredimage} in the @code{destroyinstance} function and
+@code{updateinheredimage} at the beginning of the @code{calculate} function.
+
+Example implementation:
+@example
+static int initialize(struct filter *f,struct initdata *i)
+@{struct stereogramdata *s=f->data;
+  inhermisc(f,i);
+  if(!inherimage(f,i,TOUCHIMAGE,0,0,NULL,0,0) return 0;
+  /*initialize here*/
+  return(f->previous->action->initialize(f->previous,i));
+@}
+@end example
+Also note that the fractal context holds a pointer to the fractal's palette. If
+you don't change the image's palette everything is OK; but if the child's image
+differs from the parent's, there should be two behaviors --- the fractal's
+palette is the child's one (this is common in color conversion filters, going
+from 8bpp to TrueColor and suchlike), or the fractal's palette is the parent's
+one (like in the edge detection filter). By default the fractal's palette is set
+to the parent's one, because this is most likely to be generally useful;
+anything else requires explicit work from the parent to set up the child's new
+palette.
+
+This can be changed by the @code{setfractalpalette} call, which has two
+parameters --- the @var{filter} structure, and the new palette. When you pass
+the child's palette as @var{palette}, the fractal's palette will be changed to
+the child's. If you pass @code{NULL}, changing the palette will be disabled (as
+in the motion blur filter in 8bpp mode).  This is only changeable if you still
+have access to the fractal's palette; some parent might have already redirected
+the palette beforehand, in which case this function does nothing.
+
+
+@section Calculation
+
+The calculation is done using the @code{doit} function:
+
+@deftypefn Function int (*doit)(struct filter *f,int flags,int time)
+
+This function is expected to call the child's calculation function when
+required, and apply its filter to the child's output.
+
+The @var{flags} are mostly undefined; only @code{INTERRUPTIBLE} is defined for
+now, and @emph{that} is mainly for the zooming engine so I do not describe it
+here. Nonetheless, the filter is expected to pass the @var{flags} to its
+child. Finally, @var{time} is the time in milliseconds that expired since the
+last @code{doit} call. It can be used to calculate the animation speed, perhaps
+in an attempt to keep the speed constant.
+
+@end deftypefn
+
+Calculation loops return a bitmask composed of the following flags:
+@findex ANIMATION
+@findex CHANGED
+@findex INEXACT
+@table @code
+@item ANIMATION
+ Set if the filter performs some animation, and expects that its calculation
+ function will be called again soon.
+@item CHANGED
+ Set if something changed in the output image (the usual case).
+@item INEXACT
+ This is enabled by the zooming engine in @code{INTERRUPTIBLE} mode in case the
+ @var{time} was exceeded.
+@end table
+
+Most @code{doit} functions change the image. The @var{image} structure contains
+following fields that might be significant to filters:
+@findex image
+@table @code
+@item bytesperpixel
+  Number of bytes per pixel (image depth).
+@item palette
+  Palette of image.
+@item currlines
+  Array of pointers to the beginning of each scanline in the image.
+@item oldlines
+  Like @var{currlines}, but for the previous image, when double-buffering is
+  enabled.
+@item nimages
+  Set to 2 when double-buffering is active.
+@item flipimage
+  Pointer to a function that flips @var{oldlines} and @var{currlines}.
+@end table
+
+The @var{palette} structure contains the following significant fields:
+
+@table @code
+@item type
+ Type of palette/image (@code{C256}, @code{TRUECOLOR} etc...)
+@item size
+ The number of allocated entries in the palette.
+@item pixels
+ The array of allocated entries; a conversion table mapping from the iteration
+ number to a pixel value.
+@item rgb
+ @sc{RGB} values for pixels (@code{NULL} for @code{TRUECOLOR}, @code{HICOLOR}
+ and similar paletteless types)
+@end table
+
+To make writing calculation loops for different bit-depths easier,
+@code{pixel8_t}, @code{pixel16_t} and @code{pixel32_t} are predefined. You also
+can use preprocessor magic as the edge detection filter does; this lets you
+write calculation loops just once, using @code{cpixel_t}, and the code will be
+compiled for every bitmap depth.  See the edge detection filter
+(@code{src/engine/edge.c} and @code{src/engine/edged.c}) for implementation
+details.
+
+
+@section Coordinate conversion
+
+The @code{convertup} and @code{convertdown} functions are used for converting
+screen coordinates to a position in the fractal and back. @code{convertup}
+receives coordinates in the child's image, and is expected to convert them into
+coordinates in the parent's image and call the parent's @code{convertup}
+function.
+
+@code{convertdown} is the reverse of @code{convertup} (going from parent to
+child).
+
+If coordinates correspond 1:1 you should use @code{convertupgeneric} and
+@code{convertdowngeneric}; otherwise, the implementation should look something
+like this:
+
+@example
+static void convertup(struct filter *f,int *x,int *y)
+@{
+    *y*=2;
+    *x*=2;
+    if(f->next!=NULL) f->next->action->convertup(f->next,x,y);
+@}
+static void convertdown(struct filter *f,int *x,int *y)
+@{
+    *y/=2;
+    *x/=2;
+    if(f->previous!=NULL) f->previous->action->convertdown(f->previous,x,y);
+@}
+@end example
+
+@section Filter removal
+
+Before the filter is removed from the queue, the @code{removefilter} function is
+called.  It is expected to clean up anything that the filter changed.
+
+In most cases, it should be left at @code{NULL}.
+
+@section Filter registration
+
+Once the @var{filteraction} structure is filled, the filter is ready, and you
+should try to enable it. To enable it in the user interface you need to edit
+@code{src/ui-hlp/ui_helper.c}, add the filter to the @var{uih_filters}
+structure, and increase @var{uih_nfilters}. Note that the order of filters in
+@var{uih_filter} defines the order of the filters in the filter queue.
+
+Then it is high time to start experimenting.
+
+Good luck!

+@chapter Algorithm description
+The main idea behind XaoS is that it is not necessary to calculate the whole
+image in every frame; most pixels were already calculated by the previous
+frames. You usually don't have exactly the pixels you want, but all within a
+range lower than a step between pixels are acceptable. That is why the image
+flickers a bit and why points do not blink randomly as in recalculated
+animations.
+
+   This document describes some of the most important algorithms in XaoS:
+   @itemize @bullet
+     @item Saving Previous Pixels
+     @item Approximation Algorithm
+     @item Moving Pixels to New Positions
+     @item Calculating New Pixels
+     @item Symmetry
+     @item Calculation of Mandelbrot Set
+     @item Dynamic Resolution
+     @item Autopilot
+    @end itemize   
+
+@section Saving Previous Pixels
+
+Ideally, all recalculated points should be saved and used for
+building successive frames. I could not figure out a practical way to
+implement this. To save all frames for half an hour would require 24
+Mb of memory, and searching the saved frames would be more
+computationally expensive than recalculating an entirely new frame.
+
+One way was later used by the program Frang. It remembers all pixels as
+triplets of (x,y,value), and when it builds a new image, it draws all
+the pixels that it remembers to that image and then browses the image
+and fills it with new pixels. (Possibly an @sc{rle} encoding should be
+used for calculated pixels to conserve memory.) Frang actually uses an
+algorithm that takes away pixels from the screen, so it behaves in
+exactly the same way as the algorithm described here. On the other hand,
+this method seems to require much more memory than XaoS' algorithm, and
+drawing pixels/browsing the image costs quite a lot, so the algorithm
+described here seems to be faster, since it never requires examining the
+whole image, and the new image is constructed using block move
+operations.
+
+For this reason, only the last generated frame is used as a reference.
+This way the memory requirements are proportional to @math{xsize *
+ysize}. It can be shown that this method is only about 2--5% slower
+during zooming. (Of course unzooming back to once browsed areas is much
+slower.)
+
+Because only the previous frame is used, another optimization can be
+performed: The imaginary and real parts of the calculated image are not
+precise, since they are the result of successive iterations of the
+algorithm. In order to prevent errors from being propagated to the
+following frames, their exact coordinates need to be known.
+Fortunately, it isn't necessary to save their values since it is known
+that all real components in a row and all imaginary components in a
+column are equal. Thus, the only things that must be saved are the real
+components for every row and the imaginary components for every column.
+
+This allows for a substantial speed-up in approximation because the
+calculation requires less data. Of course, some rows and columns fall
+out of the threshold and new ones need to be calculated to fill in the
+gaps in the frame.
+
+Obviously, much less work is done than in a brute-force calculation:
+there are only @math{xsize + ysize} calculations instead of
+@math{xsize * ysize}. So the main loop in XaoS looks like this:
+   @itemize @bullet
+     @item Make approximations for rows
+     @item Make approximations for columns
+     @item Move old pixels to their new positions
+     @item Calculate pixels for which there is no good approximation for
+       their row
+     @item Calculate pixels for which there is no good approximation for
+       their column, but there is one for their row
+    @end itemize
+
+@section Approximation Algorithm
+
+  @unnumberedsubsec Introduction to problem
+
+You can see that the approximation algorithm is central to the
+implementation of XaoS. If a guess is incorrect the image will look
+strange, boundaries will not be smooth and the zoom will flicker. On the
+other hand, if it adds more new rows or columns than required, zooming
+will become much slower. Also, if doubling should happen (i.e., using an
+old row or column more than once) the resolution will lower and the
+image will look jagged. It is important to keep the increasing imaginary
+and real components in the correct order. If a row and column of complex
+coordinates follows one with higher coordinate values, an improved
+approximation can be attained by swapping their values.
+
+The algorithm needs to be relatively fast. It is only used for @math{xsize + ysize}
+values, but if its speed is proportional to @math{O(n^2)}, it can be
+slower than a whole recalculation of the image. Speeds of @math{O(n)} or @math{O(n * log(n))} are acceptable.
+
+  @unnumberedsubsec Some simple algorithms to solve it
+
+Initially, a very simple algorithm was used:
+
+  Find the old row/column nearest the row/column that needs to be
+  regenerated. If the difference between them is less than one step
+  (@math{step = (end - beginning) / resolution}) then use it. Otherwise,
+  recalculate a new one.
+
+Finding the nearest row/column pair is very simple since it is always
+greater than or equal to the pair needing to be generated.
+
+Surprisingly, this simple algorithm has almost all the problems
+described above. Doubling was fixed by lowering the limit to @math{step / 2.}
+This caused a considerable slowdown so the limit was returned to @math{step}.
+Instead, the algorithm was changed to search for only row/column pairs
+that are greater than the previous frame's row/column pairs. This is
+the algorithm that was used in version 1.0.
+
+This algorithm still added too many new rows and columns, and did not
+generate smooth boundaries. For version 1.1 a heuristic was added that
+preferred approximating rows/columns with lower values. This way it
+did not occupy possible rows/columns for the next approximation. The
+result was a speedup by a magnitude of four. In versions 1.1 to 2.0
+many improvements were made to the heuristic to give it added
+performance. The following example tries to explain how complicated
+the problem is (O is the old coordinates and X is the values to be
+approximated):
+@example
+        X1        X2        X3        X4        X5        X6        X7
+O1 O2                    O3 O4 O5                   O6 O7 O8
+@end example
+
+The normal algorithm will aproximate X1 by O2, X3 by O4 but nothing
+more. For the algorithm with threshold step instead of @math{step / 2}:
+
+@example
+  O2 to X1
+  O3 to X2
+  O4 to X3
+  O5 to X4
+  O6 to X5
+  O8 to X6
+@end example
+
+But this will fail with X7. The second algorithm which relies on lower
+values will do the following:
+
+@example
+  O1 to X1
+  O3 to X2
+  O4 to X3
+  O5 to X4
+  O6 to X5
+  O7 to X6
+  O8 to X7
+@end example
+
+O1 to X1 is wrong. And there is many and many other situations that
+may occur. But you may see that the normal algorithm will calculate 4
+new rows/columns but the heuristic saves all of these calculations.
+
+  @unnumberedsubsec Current algorithms used
+
+In version 2.1 work on this heuristic was disabled after I discovered a
+surprisingly simple algorithm that solves all these problems. First I
+decided to exactly define the ``best approximation''. This should be
+done by defining a price for every approximation and choose the
+approximation with the lowest price. Prices are defined as such:
+
+  Approximating row/column x by y costs @math{dist(x, y) ^ 2}.
+
+This prefers two smaller approximation errors before a single larger
+error and describes my goal quite well.
+
+The cost for adding a new row/column specifies when it is better to do
+a bad approximation and when to add a new row/column. I use @math{(4 * step)
+* (4 * step)}. This means that the approximation is acceptable when
+@math{dist(x, y) < 4 * step}. Otherwise, adding a new row/column costs less.
+Now the best approximation is known. All that is required is a fast
+algorithm to do this. Surprisingly, this is possible in linear time
+using a relatively simple dynamic algorithm. It uses approximations of
+@math{length < n} to make a guess at the length of @math{n}. It can start by
+approximating one row/column and then again for two, three up to
+xsize/ysize rows/columns.
+
+The algorithm starts by calculating prices for all possible new
+positions for old row/column 1. Because of the pricing there are
+maximally 8 new positions. (Other ones must cost more than adding new
+row/column). Of course it is possible that there are no new positions.
+
+
+For calculating the price of approximations for row/column 2 I may use
+the previous column: Try new position n. Calculate the price and add the
+best approximation for the previous (row/column 1) that uses a new
+position lower than n (thus prohibiting doubling or swapping). This
+should be one of 8 positions or (eventually) adding a new one and not
+using row/column 1 at all.
+
+The same method can be used for the rest of the rows/columns. At the
+end the best price may be found for the last row/column and return by
+the way it was calculated. (For this I need the saved ``calculated
+using'' values.) At this step the best approximation has been
+determined.
+
+To fill the table, @math{9 * n} steps are required and n steps to
+backtrack to the best approximation. The only problem is that this
+algorithm is still a little slow (chiefly because of slow memory access
+on the Intel architectures). But, with some optimizing, it works well.
+
+This algorithm is almost perfect except that it occasionally adds new
+rows/columns to the wrong locations --- it does not prefer to add new
+rows/columns into holes --- but it does not seem that this is a real
+problem. The last optimization made was based upon the fact that added
+rows/columns do not have the exact real and imaginary components
+calculated by (@math{beginning + x * step}) but lie at the average of
+their left and right neighbors. This makes the boundaries smooth and
+distributes coordinates better. It also has the added benefit of making
+the input better for future approximations.
+
+Another danger during implementation of this algorithm is that adding new
+rows/columns into their ideal positions could cause misordered results,
+since some rows/columns could be off more than the distance between
+them. To avoid this, I use an algorithm that always examines the start
+and end of a block of new rows/columns and linearly interpolates the
+value between them. Special care needs to be taken with the blocks that
+start at the beginning or finish at the end.
+
+Implementation should be much faster using custom fixed-point
+routines --- first recalculate values such that 0 means start of image
+and 65536 means end. Than calculation is much cleaner. Values <0 and
+>65536 are off screen, calculation is independent of scale, and many
+things should be recalculated --- like tables for calculating price from
+distance.  Also dividing the main loops into many specialized parts and
+avoiding filling unnecessary parts of tables helps. So current algorithm
+in XaoS is about 5 or 6 times faster than first naive implementation.
+
+@section Moving Pixels to New Positions
+
+Since XaoS is using the approximation algorithm the following table is
+filled for every row/column:
+   @itemize @bullet
+     @item calculate
+     @item oldpoint
+     @item position
+   @end itemize
+
+calculate is 1 if the current row/column is new and needs to be
+calculated or 0 if no old pixels need to be moved. oldpoint is a
+pointer to the old row/column that corresponds to the new one. This
+pixel needs to be copied to the new location. position is the real and
+imaginary components of the coordinates used for future
+approximations. Because almost all points will be moved, the solution
+seems to be simple: for every new point look at the row and column
+table; copy it if required.
+
+There is the problem that this minimally needs three memory reads for
+every pixel (read calculate, oldpoint and index of old point). This is
+too slow, so a small optimization is performed. Instead of rewriting the
+piece of code in assembly, normal memcpy is used to move blocks of pixels
+to their new locations. This minimizes the internal loop and access can
+be done more quickly since memcpy is usually optimized for each
+architecture.
+
+Using the row table, a list of blocks to move for every row is
+created. With this new table all the pixels can be moved quickly. This
+increased the speed of XaoS by about four times and made this function
+so fast that it is no longer a problem. (In fact, it takes much less
+time than all other parts of XaoS.)
+
+@section Calculating New Pixels
+
+The above optimizations make XaoS very fast, but another 30% increase in
+speed is acquired by using a clever method for calculating the new
+pixels. Many methods are known for saving calculations during the
+generation of fractal images. The most powerful is boundary detection.
+It relies on the fact that the Mandelbrot Set is connected with lakes.
+You need only one pixel at the boundary, then can traverse the whole set
+and fill the solid area inside. This method saves many calculations but
+is too complex for adding just one line. Many claim that it does not
+introduce any errors, but this is not true. It is possible for a
+connected part of the lake to be so small that it is not visible in
+smaller resolutions. In this case, boundary detection misses the whole
+area. This algorithm is actually used just for calculating of new images
+(i.e. at the startup).
+
+XaoS uses modification of method known as solid guessing. The pixels
+at the boundaries of a rectangle are calculated. If they are all the
+same you may assume that this rectangle does not does not contain
+anything and fill it.
+
+This algorithm is further modified to operate on added lines. For this
+it is at least as good as boundary detection and produces more
+tangible errors. When adding a single line, the upper and lower line
+may be examined for the nearest three pixels. If they are all the same
+then it is assumed that 9x9 pixels are the same. This disables all
+calculations inside solid areas and calculates as many points as
+boundary detection. The only possibility of creating a larger error
+with this method as opposed to boundary detection is in the instance
+that the shape of the set is so sharp that it does not set any of the
+tested points but comes from the right (i.e., uncalculated) location.
+This situation is not very common.
+
+Later, rules were added for new rows and columns that crossed each
+other. In this instance you can test only four pixels. This situation
+is very rare. It is hoped that it does not introduce many errors.
+
+If multiple blocks of new lines need to be calculated there are no
+reference pixels to use for solid guessing. Interlacing does the
+trick. By calculating the odd lines without any guessing, the guessing
+algorithm is now possible for the remaining uncalculated lines. This
+simple trick saves about 30% of the calculation of the main Mandelbrot
+image.
+
+A similar approximation can also be done for the X coordinate. This
+makes it possible to improve solid guessing at even pixels because all
+surrounding pixels are available, further reducing errors.
+
+@section Symmetry
+
+Many fractals are horizontally or vertically symmetrical. This is
+implemented in the approximation code. When there is no good
+approximation available, try to mirror the opposite side if the line
+is available.
+
+This method primarily speeds up the initial image.
+
+@section Calculation of the Mandelbrot Set
+
+The internal Mandelbrot calculation loop is unrolled --- it calculates
+the first 8 iterations using the normal method, and then it expects that
+number of iterations will probably be large, so it switches into a mode
+where it calculates iterations in blocks of 8 with one bailout test at
+the end. When the bailout is attained, saved values from previous
+iterations are restored and the last 8 iterations are recalculated slowly
+to get exact values. This especially helps on the Pentium, where
+conditionals in floating point code are slow.
+
+Another stuff is periodicity checking. XaoS has loops with and without
+periodicity checks. In most cases it uses the no-periodicity-checking
+version. The periodicity check version is used just in the case where
+some inside-set pixel has been found during the solid guessing
+phase. This is done mainly because the periodicity checking version of
+the loop is significantly slower.
+   
+@section Dynamic Resolution
+
+The above optimizations often do not help enough and image calculation
+is still too slow. One option was to reduce the framerate, but a
+framerate lower than 5 frames per second is unbearable. Another option
+is simply to calculate only the details that can be determined within
+a time interval.
+
+Rows/columns not calculated are simply approximated by referencing the
+nearest row/column. The result is an image with larger pixels.  One
+problem is the fact that the order of calculating the rows/columns is
+significant. Previous versions of XaoS simply calculated all rows from
+top to bottom and then columns from left to right. Using the dynamic
+resolution code with this algorithm would result in distorted
+images. This was solved by adding a priority to every row/column and
+calculating the high priority row/column first. The algorithm for adding
+these priorities is as follows:
+@itemize @bullet
+  @item Find middle row/column of uncalculated block. Priority is the size
+    of the block (in floating point coordinates)
+  @item Start function for left block and right block
+@end itemize
+
+This function produces quite good results. It tends to make same-sized
+rectangles on the whole image and does not depend on resolution.
+
+Another interesting optimization is that during the zoom it is more
+advantageous to calculate rows/columns in the center of the zoom
+instead of the borders since these will be in the viewport longer and
+the user is usually focusing on the center of the zoom anyhow.
+
+This is done by simply adding to the calculated priority
+@math{normal_priority / (abs(newposition - oldposition) / step + 1)}. This
+prefers rows/columns that do not move a great deal. (Of course,
+unzooming uses the reverse of this formula.)
+
+The last variable to consider is the time interval for one frame.
+Setting it too low makes the calculation slow. Setting it too high makes
+the framerate too low. So the amount of time spent in other parts of the
+program is calculated and multiplied by 5 to determine the interval. If
+this indicates a framerate lower than 15FPS, 15FPS is used instead, since
+slower animations are unacceptable. On the other hand, if it is higher
+than 35FPS, it is set to 35FPS, since a higher framerate than that is
+just wasting computer resources. When the image is not animating, this
+value is changed, so a framerate between 5FPS and 15FPS is selected. This
+ensures that images are calculated quickly after zooming stops.
+
+@section Autopilot
+
+Another interesting algorithm controls the autopilot. It is actually
+quite simple. Interesting parts are found at the boundaries of the
+set. It randomly looks around and zooms to the first area containing
+both outside and inside set points. Some fractals (such as the Newton)
+do not have points inside the set at all. In this case it selects a
+point where many (more than 2) different colors are around. (i.e., It
+zooms into noisy areas.)
+
+In the instance that there are no such areas, the autopilot will
+unzoom. It also detects oscillations / vacillations and breaks them.
+
+The current implementation also does detection of out of range numbers;
+randomly chosen points are chosen near the old one, to avoid frequent
+changes of direction.
+
+@section SMP support
+Since version 3.0 XaoS supports SMP. This is done using threads. Most of
+XaoS routines should be threaded easily --- for example
+@code{moveoldpoints} just divides image into @math{n} equal parts and
+each part is computed by one processor. The only unthreaded part is the
+realloc table calculation routines. I don't see any way to paralellize it
+except for calculating both @math{x} and @math{y} approximations
+simultaneously (using two processors). Another interesting algorithm to
+parallelize is boundary trace; see the comments in
+@code{src/engine/btrace.c} for discussion of the current implementation.
+The only problem I see in the current implementation is the possibility
+that calculation is divided into too many parts (realloc tables, move
+points, calculate, symmetries, dynamic resolution) causing too much
+synchronization between each part. So this may be too slow on a real SMP
+box.
+
+@node timerlib, registry,algorithm ,Top
+@chapter The timer library
+
+Timer library is a library originally written for timing in XaoS; but I
+found it useful in many other programs (like demonstrations, games,
+animation players and other stuff that needs to be timed). So you should
+read this description and possibly use it in your application and save
+some coding time.
+
+There are many ways to design a timed application (such as a game)
+
+@enumerate
+@item
+Read user input, move baddies, display and loop again.
+
+This way has one disadvantage; the speed of game depends on the speed of
+the computer.  This was acceptable in olden times where the only
+processor was the Z80 :) but now with a wide variety of hardware with
+widely differing speeds such a loop is unacceptable.
+
+@item
+Read user input, measure time since last loop and calculate step for
+baddies, move baddies for set step, display and loop again.
+
+This way fixes the problem with speed. But moving baddies just for
+calculated step, that should differ a much is quite complex, usually
+introduces complex calculation, floating/fixedpoint math and other
+unnecessary stuff that makes program long and introduces many bugs.
+
+@item
+Set a fixed framerate that is high enough to make the game smooth but low
+enough to do the whole internal loop in time. The internal loop then
+looks like this: read user input, move baddies, display, measure time
+spent in loop, sleep until next frame.
+
+This is quite a popular scheme but has another disadvantage --- game can
+not be designed to use the whole CPU power, since on slower computers
+internal loop would longer than is available for one frame, so the game
+will run slowly again.
+
+@item
+To take away disadvantage of previous method, many games time just the
+moving of baddies and user input. Other stuff like displaying should be
+done in the `untimed' rest of the time. In DOS games moving and user
+input is often done in an asynchronous interrupt and drawing runs as the
+main loop. This solves the case where the drawing of the game takes a
+significantly longer time than the moving of baddies. This is quite
+common so this scheme works well.
+
+@item
+The previous scheme still has one problem --- since the timer interrupt
+works asynchronously, there could be many race conditions: if moving
+takes a longer time than the time reserved for it, the computer can
+crash. So this scheme should be enhanced into a synchronous one with
+exactly the same result but avoiding the problem with race conditions:
+
+Read user input, measure the time spent by the loop and calculate how
+many simulated frame interrupts were activated since last activation: if
+zero, sleep until simulated interrupt, move baddies as many times as
+required, display, and loop again.
+
+This is a combination of 4 and 3 and seems to be the most comfortable way
+for writing games, but since the main loop is now quite complex many
+games don't do that.
+
+@item
+there is still one small problem. Method 5 expects that moving takes a
+significantly smaller time than displaying. This may not be the truth. A
+simple work around is to write a moving routine that should move for
+@math{x} moves in a faster way than calling move @math{x} times. This is
+often possible, and makes extension to scheme 5 easy. This scheme allows
+you to use a very large maximal framerate (say 100FPS) and to have the
+same results as method 2 (which is the maximally exact method)
+@end enumerate
+
+As you can see, designing the main loop isn't so easy. This is just a
+very simple example: a more advanced application might want to move one
+set of baddies at one framerate and another at a different
+framerate. This requires two such timings. Another complication is that
+there are many different ways to measure time exactly on different
+platforms. Under Linux you can measure using @code{gettimeofday}, but
+under DOS this is exact to just 1/18 of second and thats too low for
+smooth animation, and so on.
+
+That's why I decided to design a portable easy to use timer library, that
+makes it easy to implement all methods described above, combinations of
+them, and much more.  During the design I took care of the following
+things: quality of timing, how easy to use it is, speed, portability and
+to minimise unexpected situations (like race conditions in asynchronous
+interrupts and so on)
+
+@section The name of the game
+
+The timer library operates with @dfn{timers}. They should be created, you can
+measure time since last reset, pause them or set @dfn{handler} and
+@dfn{interval}. But handler is not yet activated at the given interval. Since
+timer library is not asynchronous, you must activate them yourself.
+
+For activating @dfn{groups} are used. You should process a group at some place
+in your program, whereupon all timers in the group are checked and their
+handlers activated if required. When the time spent since last activation is
+higher than the interval, the handler is activated more than once. Also, the
+interval to next invocation is calculated to keep frequency.  Simple scheduling
+is performed for handler --- handler is activated just once and then all other
+timers are checked before it is activated again. You can also define a
+multihandler --- a handler that is activated just once and receives as an
+argument a count of intervals.
+
+There are two special groups --- @code{asyncgroup}. Timers in this group are
+activated asynchronously (as though they were called from interrupts). Thisis
+not recommended, since the asynchronicity brings many problems and usually isn't
+required. Also it does not work on many platforms. @code{syncgroup} is the
+default group. The program is expected to process it quite often. If you don't
+need to use more than one group, you should use this one.
+
+Time in timerlib is bit strange, since it does not flow continuously but
+jumps. It is updated every time you call @code{tl_updatetime}. I did this in
+order to minimize context switches, but later I found this scheme very useful,
+since you normally look up the timer, do something and then reset it and don't
+want to worry about any time spent between lookup and reset. This helps to keep
+frequency of timers exact w/o any errors caused by such situations. At the other
+hand you need to call @code{tl_updatetime} at least once in your main loop.
+
+Maybe you don't know why you'd want to create more groups, but I found it quite
+useful.  For example, an autopilot in XaoS has such a special group --- I need
+to call it approx. every 1/20 of second, but just at one place in the
+program. Invocation of the autopilot when calculation is active would produce
+incorrect results, so I have a special group for autopilot and process it in
+just one place where I am sure it is safe.
+
+Timers can also be emulated. You can stop them and then control the flow of time
+for given timer. This should be quite useful; for example, when you want to
+precalculate animation at a given framerate.
+
+To control a group of timers, you can create @dfn{emulators}, which are just
+other timers controlled by you. They are useful in cases where you want to
+emulate fixed framerates (for animation rendering) or suchlike.

+@chapter XaoS function registry
+
+XaoS has an ui helper library, which provides functionality used by the user
+interface. All its useful functions are registered into a central registry.
+This registry is used to generate menus and dialogs as well as command line
+options or scripting language; so it is a very significant thing in XaoS design.
+
+This is not just useful for those who want to hack XaoS ui-helper layer, but
+also for authors of drivers, who can use this to add new driver dependent
+functions into XaoS's menu. The external user interface is also based on the
+registry.  The main idea behind external user interfaces@footnote{currently one
+for Tcl/Tk and Gtk is under development} is this: XaoS transfers its registry to
+the interface (using asimple description language). The user interface starts
+XaoS in its window and builds menus and dialogs based on the registry. Then,
+once user selects some function, the user interface creates a command in XaoS'
+scripting language and sends it back to XaoS' engine.
+
+Knowledge of this part is thus essential for many developers. Please pay
+attention. :)
+
+The implementation of the registry is in @code{xmenu.c}, and the header is
+@code{xmenu.h}. For historical reasons, it talks about menus and dialogs (it was
+originally designed for the GUI). I am keeping this terminology, since it is
+quite clean and easy to understand instead of talking in some cryptic abstract
+terms.
+
+@section Function description
+
+To add a function into the database, you need to put a description into the
+@var{menuitem} structure. It has the following definition:
+
+@findex menuitem
+@example
+typedef struct menuitem
+  @{
+    char *menuname;
+    char *key;
+    char *name;
+    char *shortname;
+    int type;
+    int flags;
+    void (*function) ();
+    int iparam;
+    void *pparam;
+    int (*control) (struct uih_context *);
+    menudialog *(*dialog) (struct uih_context *);
+  @}
+menuitem;
+@end example
+
+@defvar menuname
+Name of menu (or category) the function belongs in. The root of all categories
+is called @code{"root"}. XaoS also uses an @code{"animroot"} when animation
+replay is active. If you are adding a function, it is better to add it into some
+subcategory like @code{"ui"} (which will place it into the UI menu) or to create
+a new category for your functions, which will appear as a submenu of the main
+menu in the UI.
+@end defvar
+
+@defvar key
+@sc{ASCII} code of the hotkey that activates this function. Use @code{NULL} if
+none.
+@end defvar
+
+@defvar name
+Longer name of the function, used in the menu entry, or @code{xaos --help}
+listing.
+@end defvar
+
+@defvar shortname
+One-word name of function used in command language and other references to
+the function.
+@end defvar
+
+@defvar type
+Type of function --- this is @emph{not} the return type. @var{type} should be
+one of the following constants:
+@table @code
+@findex MENU_SUBMENU
+@item MENU_SUBMENU
+   A submenu. This is not a function, but a name for the submenu. You can fill
+   in the @var{key}, @var{name}, and @var{shortname}. The name of this new
+   submenu is placed in the field @var{pparam}.
+@findex MENU_NOPARAM
+@item MENU_NOPARAM
+   A normal function without any parameters. When activated,
+   @var{function} will be called with a pointer to @code{uih_context} as its
+   parameter.
+@findex MENU_INT
+@item MENU_INT
+   This should be used to simplify entering of many similar functions (handled
+   by just one universal function in the C code). The @var{function} is handled
+   in the same way as @code{MENU_NOPARAM}, but also one integer parameter taken
+   from @code{iparam} is passed in.
+@findex MENU_STRING
+@item MENU_STRING
+   Similar to @code{MENU_INT} but uses a string instead of an integer.
+@findex MENU_DIALOG
+@item MENU_DIALOG
+   If your function needs some paramters, use the dialog structure to describe
+   them. In the scripting language your function then have parameters; in
+   the user interface, a dialog will be displayed. @var{pparam} must point
+   to array of dialog entries (writing them will be described later).
+   If your function has just one parameter described in the dialog structure, it
+   will be called in the normal C way --- if you want a string parameter, one
+   pointer pointing to a string (in addition to @code{uih_context}) will be
+   passed to the functions.
+
+   If multiple parameters are requested, it is impossible to call
+   function in a C way without a special wrapper for each case. So it will
+   receive a pointer to an array of @code{dialogparam} unions, wich contain
+   one entry for each parameter. @code{dialogparam} is declared as follows:
+@example
+typedef union
+  @{
+    char *dstring;
+    int dint;
+    number_t number;
+    number_t dcoord[2];
+    xio_path dpath;
+    void *dummy;
+  @}
+dialogparam;
+@end example
+@findex MENU_CDIALOG
+@item MENU_CDIALOG
+   In some cases, it is useful to add some context specific default values
+   to the dialog structure. In this case you might use this type instead. In
+   this case the function @var{dialog} is called first, and it is expected to
+   return a pointer to the correct dialog structure. The dialog structure must
+   lie in static storage (since it is not freed), and must always have the same
+   fields, and differ only in the default values.
+   This function must also work correctly even when the pointer to
+   @code{uih_context} is @code{NULL}, since it is often called in the
+   initialization stages (parameter parsing etc.)
+@end table
+@end defvar
+@defvar flags
+The @var{flags} are used to set additional information about the function:
+@table @code
+@findex MENUFLAG_CHECKBOX
+@item MENUFLAG_CHECKBOX
+Some features act like check-boxes --- i.e. repeated calls to the function
+toggle the features. In menus it is useful to add a check-box for this function
+indicating whether the feature is on or off. This flag adds such a check-box.
+
+So that the UI can determine the current state of the checkbox, you need to
+define the function @var{control}, which returns @code{1} when enabled and
+@code{0} when disabled.  In order to let external GUIs work correctly you also
+need to call @code{uih_updatemenus("name")} every time the state of this
+function changes.
+
+In the scripting language, this adds a single parameter, either @code{#t} or
+@code{#f}. The engine then calls the function only when necessary. When
+@code{#t}, a dialog is requested; when @code{#f}, the function is called just as
+@code{NOPARAM}. I.e. the dialog is displayed only when enabling the feature.
+
+@findex MENUFLAG_DIALOGATDISABLE
+@item MENUFLAG_DIALOGATDISABLE
+Display dialog on disabling of this checkbox feature, instead of on enabling.
+@findex MENUFLAG_RADIO
+@item MENUFLAG_RADIO
+Other features act like radio-buttons. Control functions in this case receive
+the same parameter as is defined for @code{MENU_INT} or @code{MENU_STRING}
+types, and is expected to return @code{1} when enabled and @code{0}
+otherwise. You also need to call @code{uih_updatemenus} when the value is
+changed. No special parameter is added in the scripting language.
+
+@findex MENUFLAG_INTERRUPT
+@item MENUFLAG_INTERRUPT
+Interrupt current calculation when this function is called (used by functions
+with cause recalculation of the screen)
+
+@findex MENUFLAG_INCALC
+@item MENUFLAG_INCALC
+By default XaoS queues functions and calls them later when they are activated in
+the calculation. This flag disables this feature.
+
+@findex MENUFLAG_ATSTARTUP
+@item MENUFLAG_ATSTARTUP
+By default XaoS queues functions and them calls later when they are activated as
+command line parameters (in case the engine is not fully initialized yet).  This
+flag disables this feature.
+
+@findex MENUFLAG_NOMENU
+@item MENUFLAG_NOMENU
+If set, the function will not be visible in the menu.
+
+@findex MENUFLAG_NOPLAY
+@item MENUFLAG_NOPLAY
+If set, the function will not be available as a command in scripts (and therefore
+won't be usable by external GUIs).
+
+@findex MENUFLAG_NOOPTION
+@item MENUFLAG_NOOPTION
+If set, the function will not be available as a command line option.
+@end table
+@end defvar
+
+@section Initializing the menuitem structure as a static variable
+In most cases, menuitems should be written as static variables. Because the
+contents of this structure could change in future, please use one of the macros
+defined in @code{xmenu.h}. They provide a cleaner and easier to extend way to
+define these entries than does doing it by hand.
+
+For example to define a @code{MENU_NOPARAM} function, use the following macro:
+@defun MENUNOP (menuname, key, name, shortname, flags, function)
+@end defun
+Similar macros exist for other types too. They end in @code{CB} or @code{RB} for
+check-boxed or radio-box functions. See @code{src/ui-hlp/menu.c} for a large
+number of example definitions. They should look like this:
+
+@findex menuitem
+@example
+static menuitem menuitems[] =   /*XaoS menu specifications */
+@{
+  SUBMENU ("", NULL, "Root menu", "root"),
+  SUBMENU ("", NULL, "Replay only commands", "plc"),
+  MENUNOP ("comm", NULL, "print menus specifications of all menus",
+           "print_menus", MENUFLAG_NOMENU|MENUFLAG_NOPLAY|MENUFLAG_ATSTARTUP,
+           uih_printallmenus),
+           ...
+@end example
+
+@section Dialog description
+A dialog description is similar to a menuitem. It is an array of the following
+structures:
+@example
+typedef struct dialog
+  @{
+    char *question;
+    int type;
+    int defint;
+    char *defstr;
+    number_t deffloat;
+    number_t deffloat2;
+  @}
+menudialog;
+@end example
+It is terminated by an element with the @var{question} pointer set to
+@code{NULL}.
+
+The @var{question} contains the string the UI should display when it asks for
+this field.
+
+@var{type} should be one of the following values:
+@code{DIALOG_INT}, @code{DIALOG_FLOAT}, @code{DIALOG_STRING},
+@code{DIALOG_KEYSTRING} (the difference between string and keystring is that
+in the scripting language string is passed as @code{"hello"}, but keystring is
+passed as a Scheme keyword: @code{'hello}), @code{DIALOG_IFILE} (input file),
+@code{DIALOG_OFILE}, @code{DIALOG_CHOICE} (choice between different
+keystrings), @code{DIALOG_ONOFF} (boolean parameter), @code{DIALOG_COORD} (two
+floats --- a complex number)
+
+Set the corresponding @var{def*} field to set the default value. In the case of
+files, use a string in the format @code{"@var{[prefix]}*@var{[extension]}"}. For
+type @code{DIALOG_CHOICE} set @var{defstr} to a pointer to an array of strings,
+terminated by a @code{NULL} entry.
+
+To write dialog structures, as with menus, use macros defined in @code{xmenu.h}
+like:
+@example
+DIALOGSTR(question,default)
+@end example
+The definition should look like:
+
+@findex menudialog
+@example
+static menudialog uih_viewdialog[] =
+@{
+  DIALOGCOORD ("center:", 0, 0),
+  DIALOGFLOAT ("Radius:", 1),
+  DIALOGFLOAT ("Angle:", 0),
+  @{NULL@}
+@};
+@end example
+@section Modifying the registry
+@deftypefn Function void menu_add (menuitem *@var{item}, int @var{n});
+Add an array of @var{n} items to the database.
+@end deftypefn
+@deftypefn Function void menu_delete (menuitem *@var{items}, int @var{n});
+Remove an array of @var{n} items from the database.
+@end deftypefn
+@section Querying registry
+@deftypefn Function menuitem* menu_findkey (char *@var{key}, char *@var{root});
+Find item for given key. @var{root} is menu to start (submenus are searched
+recursively).
+@end deftypefn
+@deftypefn Function menuitem* menu_findcommand (char *@var{name});
+Find item for given short name.
+@end deftypefn
+@deftypefn Function char* menu_fullname (char *@var{menu}); 
+Return a long name for a menu, given a short name.
+@end deftypefn
+@deftypefn Function menuitem* menu_item (char *@var{menu}, int @var{n}); 
+Return the @var{n}th entry in the @var{menu}. Return @code{NULL} if that entry
+does not exist.
+@end deftypefn
+@deftypefn Function int menu_enabled (menuitem *@var{item}, struct uih_context *@var{c}); 
+Check whether the given item is activated (for check-boxed and radio-boxed
+functions).
+@end deftypefn
+@deftypefn Function int menu_havedialog (menuitem *@var{item}, struct uih_context *@var{c});
+Return whether this function has an associated dialog.
+@end deftypefn
+@defun menu_getdialog (@var{context}, @var{m})
+This macro returns a pointer to the dialog structure for a given menu item. (If
+the item doesn't have a dialog, garbage is returned).
+@end defun
+@deftypefn Function int menu_available (menuitem *@var{item}, char *@var{root});
+Check whether an item is available as one of the entries of @var{root} (or it's
+submenus)
+@end deftypefn

+README file for help/ directory
+-------------------------------
+
+Zoltan Kovacs <kovzol@math.u-szeged.hu>
+
+Last modification information:
+$Header: /home/jblang/XaoS-cvsbackup/XaoS/help/README,v 1.1 2003-02-03 10:16:51 kovzol Exp $
+
+
+This directory contains several files for documentation of XaoS.
+
+The main file is xaos.hlp. From this will all scripts generate
+documentation files.
+
+To create HTML documentation (many .html files), please run
+"make html".
+
+To create TeX documentation (.dvi files) or .info files, go to ../doc
+and type "make".
+
+To create .rtf documentation, type "make rtf" or run "rtfconv.bat" (on
+Windows/CygWin development system). You will need xaoswin.rtf in order
+to generate xaoswin.hlp for your running Windows executable.
+
+To create xaoswin.hlp, you need the HCW package. Note that you also need
+xaoswin.Hpj and xaoswin.rtf (xaoswin.rtf must be generated with
+"make rtf" or using the "rtfconv.bat" utility).
+
+Finally, "make" will generate both .html and .rtf documentation.

+X11 driver
+==========
+
+This was the first driver done for XaoS. It supports many visuals, shared
+colormaps and MitSHM extension.
+
+Bugs/limitations:
+
+XaoS makes some X servers too busy
+
+    Sometimes XaoS generates images faster than X can display them. In this
+    case XaoS responds poorly to the mouse, and other applications slow down
+    too. This happens especially often on old R4 servers. Use -sync to avoid
+    this problem. Note that -sync does not make all communication with X
+    asynchronous; it just adds one additional XSync call. So the slowdown is
+    not as large as you might expect.
+
+Does not work on all visuals
+
+    This driver supports only 8bpp pseudocolor/grayscales, 15,16,24 and 32bpp
+    truecolor, 1bpp and 8bpp staticolor visuals.
+
+Palette rotating does not work for 8bpp pseudocolor w/o private palette
+
+X11 driver was written by Jan Hubicka and Thomas Marsh, 1997.

+
+AA-lib driver
+=============
+
+The AA driver is currently the most advanced and portable driver for XaoS. It
+is based on AAlib--a high quality ASCII-art library developed by the
+`AA-project`_. 
+
+.. _`AA-project`:
+    http://aa-project.sourceforge.net/
+
+It is a fully featured XaoS driver for text mode displays. It supports 256
+colors and the mouse where possible.
+
+It also has some extended features available from the UI menu:
+
+Attributes
+
+    AA-lib may use character attributes to improve image quality. By default it
+    uses normal, dim and bold characters where possible, but you can also
+    enable different attributes like reversed or bold font characters. You may
+    also enable usage of non ansii/reversed characters if your device supports
+    it.
+
+Font
+
+    AA-lib uses a bitmap image of the font to prepare the approximation table
+    used for ASCII art rendering. This bitmap is expected to be same as the one
+    used by your device. AAlib performs detection where possible however some
+    devices (like UNIX text terminals or MDA) do not support this. AAlib has
+    few font images compiled in, so in this case you should try to use one of
+    them to achieve best results.
+
+Inversion
+
+    Some devices use inverse video: use this to get correct results on such
+    devices.
+
+Dithering mode
+
+    Dithering is an way to get more exact color in approximations, by combining
+    more characters; but this method can produce ugly looking noise on certain
+    images. Use this menu to disable or tune it.
+
+Palette options
+
+    By default AA driver uses the XaoS palette to render images, but it quite
+    often looks ugly on text displays. Here you can choose a special text
+    palette instead. Note that with filters enabled, the results may be rather
+    ugly. This function is available from the **palette menu**.
+
+Save text screen
+
+    The normal save function will generate a PNG image instead of nice
+    ASCII-art. To save ASCII art use this function instead. It supports many
+    text file formats like HTML, ANSI, more, etc... It will also ask you for
+    font and attributes(see above). It is available from the **file menu**.
+
+The AA-lib driver also provides the full set of standard AA-lib's command line
+options. You may use them to tune parameters like gamma correction, and so on.
+See xaos -help or the AA-lib documentation for details.
+
+The AA driver was written by Jan Hubicka, 1997.

+Adding Built-in Formulas
+========================
+
+.. highlight:: c
+
+This provides developers an overview of how XaoS handles built-in formulas
+and how to add one.
+
+Built-in formulas are defined in :file:`/src/engine/formulas.c`. 
+
+Defining the Formula
+--------------------
+
+Each formula is defined by a block of ``#defines``, followed by ``#include "docalc.c"``, 
+like this::
+
+	#ifdef __i386__
+	#define UNCOMPRESS
+	#endif
+	#define USEHACKS
+	#define PRETEST 0
+	#define FORMULA \
+		rp = zre * (rp - 3 * ip); \
+		zim = zim * (3 * zre * zre - ip) + pim; \
+		zre = rp + pre; \
+		rp = zre * zre; \
+		ip = zim * zim;
+	#define BTEST less_than_4(rp+ip)
+	#define SMOOTH
+	#define SCALC smand3_calc
+	#define SPERI smand3_peri
+	#define CALC mand3_calc
+	#define PERI mand3_peri
+	#define JULIA mand3_julia
+	#define RANGE 2
+	#define RPIP
+	#include "docalc.c"
+
+Every time you include :file:`docalc.c`, it means something different depending
+on how you have defined the macros. 
+
+Adding the Formula Description
+------------------------------
+
+After you have defined the macros, there are two other things are to do:
+
+You must put the description of your formula at the end of
+the structure named "formulas". You can make it to be similar to the
+other formula descriptions.
+
+	1. FORMULAMAGIC
+	2. CALC function
+	3. PERI function
+	4. SCALC function
+	5. SPERI function
+	6. JULIA function
+	7. {"Name of Mandelbrot", "Name of Julia"}
+	8. "short name"
+	9. point of view: {x_translate, y_translate, ?, scale}
+	10. hassymmetry
+	11. isMandelbrot (or Julia, at startup)
+	12. pre -- real part of Julia seed
+	13. pim -- imag part of Julia seed
+	14. {{}{}... structures about the symmetries of the outcoloring modes}
+	15. {{}{}... structures about the symmetries of the incoloring modes}
+
+		The symmetry structures take the form:
+		{vertical_symmetry, horizontical_symmetry, size_of_other_symmetries, other_symmetries}
+
+		Horizontical and vertical symmetries can be INT_MAX or 0, 
+		INT_MAX means no symmetry, 0 means symmetry
+		The next two is like: {... 2, sym6} {... 2, sym8} or {... 6, sym16}
+
+	16. some FLAGS, (I still don't know what they mean.)
+
+
+Adding Function Calls to the Formula
+------------------------------------
+
+When this is done, you must put your new functions in the four switch commands at the end of the file.
+
+After compiling XaoS, you should find your fractal at the "More Formulae" menu.

+
+Antialiasing
+============
+
+Antialiasing is a technique to increase image quality by eliminating jagged
+edges. XaoS calculates four values for each pixel (on the subpixel boundaries)
+and uses the average of them for the pixel value.
+
+This filter slows XaoS down a **lot** and greatly increases memory
+requirements. It is useful mainly when you want to save images and want to make
+them look as nice as possible. Antialiasing also helps a lot when you want to
+encode JPEG or MPEG files; they are much shorter if antialiased (MPEG and JPEG
+hate jagged edges).

+Background
+==========
+
+What is XaoS?
+-------------
+
+XaoS is a realtime interactive fractal zoomer. This means that it lets you
+zoom smoothly into any place in the fractal you choose without the many hours
+of calculation required by most other fractal generators. It now has many
+other features too, like different fractal types, autopilot, special coloring
+modes, support for various bit depths (8bpp, truecolor, hicolor and realcolor),
+random palette generation, color cycling, etc.
+
+Why yet another fractal generator?
+----------------------------------
+
+We decided to make XaoS, because all fractal browsers we know of take a
+long time to calculate each image. You may browse nice images
+generated by them but real impressions of fractals --- the self
+similarity and infinite zooming into the nice parts of fractals ---
+can be seen only in animations. There are many programs available that
+make nice animations, but they take a long time to calculate and lots
+of space on disk. Most such animations are quite ugly because their
+authors can't see them without many hours of calculations.
+
+A natural question is: is it possible to generate such animations in
+real-time? The answer was negative for many years, since the Mandelbrot set is
+very computationally expensive. Things are changing. Today's computers
+are fast enough to calculate approx. 10.000 of pixels per frame,
+which is enough 
+for a very low resolution animation (100x100). Several programs doing that
+are available. But 100x100 animation still looks quite ugly. To make
+animation nice you need at least 320x200 pixels. And that is 6 times more!
+One possibility is to wait until computers will be fast enough, but
+it will take many years, and then 320x200 animations will be obsolete
+and everyone will want 1024x768 resolution instead or more.
+
+We found a special algorithm that saves up to 99.98% of calculations during
+zooming by reusing pixels already calculated in previous frames. There were
+some programs doing similiar tricks before but we don't know about any able
+to do zooming interactively with a speed similar to XaoS. Many other tricks
+were later implemented XaoS to achieve yet higher framerates. Now XaoS does
+up to 120 frames per second on a 120Mhz pentium in a fullscreen 320x200
+animation, and calculates an average of 160 (0.24%) pixels per frame. This makes
+XaoS fast enough to achieve its primary goal, realtime animation, but there
+are still many areas that could improve, since more complex fractals,
+higher resolutions, or slower computers still bring many problems.

+Bailout
+=======
+
+Bailout is the value which is checked for each point of the orbit if the point
+is far enough from the complex zero point in the current iteration. If the
+point is far enough, then the iteration immediately stops and the starting
+point on the screen will be painted with a given colour, depending on the
+fractal type and many other settings.
+
+For the :ref:`Mandelbrot set <mandel>` this value is 4. Other fractal types
+usually have the same bailout value. For most fractals many bailout values give
+more or less similar output. E.g., for the second order Mandelbrot set one can
+prove that the sequence \|z\| (z:=z^2+c) tends to infinity if and only if \|z\|>2
+for some element z of this sequence. In XaoS program, Bailout value is the
+square of this 2, i.e. you can change this to any value greater than 2 for
+similar results.
+
+Other fractal types may use other bailout values. The default is 4 for each
+types.

+Mac OS X
+========
+
+XaoS has full support for Mac OS X including native menus, dialogs, help,
+Finder integration, drag and drop, and basic AppleScript support.
+
+The Mac OS X port of XaoS strives to provide a Mac-like experience, while
+retaining compatibility with other platforms. Some Mac-specific details are
+outlined below.
+
+Zooming
+-------
+
+Since most Macs have one button mice, the middle and right buttons are emulated
+with modifier keys. This means there are multiple ways to perform basic zooming
+operations:
+
+Zoom in
+
+    Hold down the main mouse button.
+
+Zoom out
+
+    1. Hold down the Ctrl key while pressing the main mouse button. 2. Use the
+    right mouse button if you have one. 3. On laptops with gestures enabled,
+    place two fingers on your trackpad and press the main mouse button.
+
+Pan
+
+    1. Hold down the Shift key while dragging with the main mouse button. 2.
+    Drag with the center button if you have one. 3. Use the scroll wheel or
+    ball if you have one to pan up/down and left/right. 4. On laptops with
+    gestures enabled, swipe two fingers across the trackpad to pan horizontally
+    or vertically.
+
+Keyboard Shortcuts
+------------------
+
+XaoS menu functions have been mapped to commonly used Mac keyboard shortcuts.
+For example, Open is Cmd-O and Undo is Cmd-Z, just as you would expect.
+
+However, XaoS also has its own long-standing tradition of cross-platform
+keyboard shortcuts. These keyboard shortcuts are also displayed in the menus
+inside parentheses. For example, the menu item "Autopilot (a)" means that you
+can press a (with no modifier keys) to activate Autopilot. All of these
+traditional XaoS shortcuts do not use modifier keys, so they do not conflict
+with any standard Mac OS X shortcuts.
+
+In some cases, the same function may be performed with both a traditional XaoS
+shortcut and a Mac OS X-specific shortcut. You can choose whichever one is more
+comfortable for you.
+
+Full Screen Mode
+----------------
+
+The Mac OS X port supports a full screen mode. To enter it, select **Mac OS X
+Full Screen Driver** from the **UI -> Driver** submenu. Once you enter full
+screen mode, the menu bar will automatically hide. To access the menu bar, move
+your mouse to the top of the screen and the menu bar will slide into view. When
+you move your mouse away, it will automatically disappear again. To return to
+windowed mode, select **Mac OS X Windowed Driver** from the **UI -> Driver**
+submenu.
+
+Videator Support
+----------------
+
+XaoS for Mac OS X can send a live video stream to Stone Design's Videator_, 
+which can then do post-processing using Mac OS
+X's core video technology. This combination creates mind-blowing visuals that
+are great for VJing (live video performance art).
+
+.. _Videator:
+    http://stone.com/Videator/
+
+To turn on output to Videator, select **Videator Output** from the **UI** menu.
+See these instructions_ for more details on using Videator with XaoS.
+
+.. _instructions:
+    http://stone.com/Videator/VJ.html
+
+Known Issues
+------------
+
+Catseye fractal does not render properly.
+
+    Workaround: Set the bailout to just over 4 (e.g., 4.000000001). After
+    changing this setting, the fractal renders as expected.
+
+The Mac OS X driver was written by J.B. Langston, 2006-2008.

+==============

+You can use the mouse to zoom in and out. The pan function allows you to drag and drop the image in any direction to change the center without zooming in or out. The button you press determines the action performed:

+=========================  ==================================  =========================
+
+On Macs with a single button mouse, use the Mac equivalents to simulate the other buttons.  XaoS offers two additional ways to pan on a Mac:
+
+* On a Mac laptop, `swipe two fingers`__ across your trackpad to pan in any direction.  
+* If you have a Mighty Mouse, you can pan the image using your scroll ball.
+
+__ http://support.apple.com/kb/HT3448
+
+.. note::
+
+	The behavior of the mouse buttons can change when special modes are enabled. 
+	If you enable rotation, the first button is used to rotate the image. Also, 
+	in fast Julia mode, the first button is used to change the seed.
+
+
+After few minutes of zooming you will probably exceed the precision and the
+fractals will get boring. If you are getting strange big rectangles on the
+screen, you probably reached the numeric limit: there is no way to avoid this
+except un-zoom back and choose a different area. It doesn't hurt so much, since
+you have zoomed approximately 64 051 194 700 380 384 times, so there are quite
+a lot of areas to explore. Algorithms with unlimited precision exist, but they
+are still too slow for real-time zooming.
+
+The other possibility is that you have reached the iteration limit. The fractal
+is calculated approximately, and in this case you need to increase number of
+iterations used for approximation (and decrease the speed in the process). This
+is done from the menu or using the arrow keys **Left** and **Right**.
+
+An **Up** and **Down** keys should be used to change zooming speed. Note that
+higher speed costs more and image will be blocky.
+
+This behavior can also change. With palette cycling enabled, **Left** and
+**Right** keys change cycling speed; in continuous rotation they change
+rotation speed.
+
+All other functions are available from the menu, which (in the default
+configuration) are displayed when you move the mouse to the top of the
+screen/window. It is useful to learn the shortcut keys, which are shown in gray

+DirectX fullscreen driver
+=========================
+
+This is da river for Windows 9x and NT. It is new since version 3.1 and because
+of some oddities of Windows API and kludges in DirectX it may be rather
+unstable. Please report all bugs. In case of problems you could use the DOS
+version of XaoS instead.
+
+This driver allows the Windows port of XaoS to run in full screen mode. The
+driver supports 256, 65536 and 16777216 color modes (24bpp and 32bpp) in all
+resolutions supported by DirectX. You can change graphics mode by pressing the
+= key (or by using the UI/Resize menu). If the selected mode is not supported,
+the driver will restore the previous setting.
+
+Use the -mode WIDTHxHEIGHTxDEPTH (like -mode 640x480x16) command line option to
+change graphics mode.
+
+If you want to start XaoS in DirectX, use the -driver dX-fullscreen option.
+
+See the :ref:`Win32 driver <win32>` documentation for some more Windows
+releated information.

+
+The DirectX driver is an alternative to the windowed :ref:`win32 driver

+almost the same behaviour as the :ref:`win32 driver <win32>` so please read its
+documentation for more details. The only difference should be the display
+speed.
+
+The driver supports only hicolor and truecolor modes. There is no support for
+256 and 16 color modes because of palette collision problems. The win32 driver
+will be used in these cases by default, so this should cause no problems.
+
+If you are experiencing problems with this driver, you might want to use the

+Dynamic resolution
+==================
+
+**Syntax**:(fastmode keyword)
+
+XaoS performs many optimizations, but fairly often this is not enough. In order
+to keep a high framerate, XaoS automatically lowers the resolution of the
+image, increasing it when there is time for more calculation. This feature is
+enabled by default when animating, but you might also like to enable it for new
+images (which makes the image 'come into focus' when it is recalculated from
+scratch for whatever reason), or disable it completely if you don't like it.
+
+In the scripting languge, the keyword should be one of the following:
+
+'never
+
+    Disable dynamic resolution
+
+'animate
+
+    Use only for animations (default)
+
+'new
+

+File Format
+===========
+
+.. highlight:: scheme
+
+This section describes the format used by XaoS for animations, configuration
+files and saved positions. All these files have a common format, designed to be
+easily readable, to allow manual editing of files and easy conversion by other
+programs.
+
+I also taken care to make it easily extensible for future versions of XaoS so I
+hope there will not be many incompatibilities between various XaoS versions.
+
+The format is a simple set of commands executed sequentially. XaoS does not
+provide any variables/cycles as usual scripting languages do, but future
+extension to full-blown Scheme should be easy since the format uses Scheme-like
+syntax. The syntax of every command is::
+
+	(command_name [param1] [param2])
+
+where parameters are optional and separated by whitespace (an arbitrary number
+of spaces, tabs and newlines). The parameters can have the following types:
+
+integer
+    number w/o decimal point (123)
+
+float
+    floating point number in decimal notation with optional exponent (1.23E2)
+
+keyword
+    text started by quote '. It is used to pass various string constants like
+    formula name ('mandel) Quote is required for scheme compatibility
+
+string
+    Text inside double quotes. The only parameter that should contain
+    whitespace
+
+boolean
+    #t for true or #f for false
+
+There is a complete description of all XaoS functions (with some examples) and
+an index of functions in the :ref:`XaoS registry <menus>`. You may particularly want to
+read about the :ref:`animation functions <animf>`. Also, the following functions are
+significant:
+
+load
+    This function loads and interprets a file. It works similarly to #include
+    in C.
+
+initstate
+    Available in version 3.0 and above, this function resets XaoS's state to
+    default values. This command should be at the beginning of each animation
+    file, since otherwise some stuff previously enabled by user could cause
+    unexpected effects. State is not reset by default before playing animations
+    since it would make it impossible to write macros. Current versions don't
+    really need macros, but in future versions, when the Scheme programming
+    language will be available, this should be a much more interesting subject.
+
+usleep
+    This function waits for a selected amount of time(in usec) before
+    processing the next command. The screen is recalculated and displayed at
+    the beginning of the sleep if necessary. The remaining time is spent by
+    waiting, calculating if necessary, or performing any animation you entered
+    via animation commands.
+
+wait
+    Waits until the animation or image rendering is complete. Do not call this
+    function when zoom, or continuous rotation is active otherwise deadlock
+    happens. It is a good idea to call it immediately before text subtitles are
+    displayed, since it looks ugly when they are displayed over a blocky
+    unfinished fractal. Because the degree of blockiness at a given instant is
+    a function of your machine speed, it may look nice for you but ugly for
+    others with slower machines. Also you should call this after an animation
+    is performed, before the switch to another fractal happens; since the
+    switch involves calculation, the screen is stopped for a while and an
+    unfinished fractal there looks ugly. You should also call it, when you want
+    to do something as soon as possible.
+
+Example::
+
+	;configure everything for the first frame
+	(inistate)
+	(palette 1 1163254293 0) ;custom palette
+	(cycling #t) ;enable cycling
+	(cyclingspeed 7)
+	(maxiter 276) ;higher number of iterations
+	(range 3) ;default range for solid guessing
+	(usleep 1000000) ;second frame starts here
+	(moveview -1.8101154154614007889 -8.2687205907162041209E-05)
+	;just move the image
+	(usleep 1000000) ;third frame
+	(morphview -1.8101154154614007889 -8.2687205907162041209E-05
+	6.277210971069452361E-10 6.2772109785334669875E-10)
+	;10 seconds of zooming into selected
+	rectangle
+	(usleep 100000000)
+
+The best way to learn XaoS command language is probably to read position files
+and modify them. For example, to create zooming animation from the original
+file::
+
+	(initstate)
+	(defaultpalette 0)
+	(formula 'mandel)
+	(view -1.64128273713 -5.50393226816E-05 9.69332308848E-08 9.69332308834E-08)
+
+Just change the view command to morphview, and add usleep::
+
+	(initstate)
+	(defaultpalette 0)
+	(formula 'mandel)
+	(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08 9.69332308834E-08)
+	(usleep 10000000)
+
+The following code produces Julia morphing in the real axis::
+
+	(initstate)
+	(fastjulia #t)
+	(juliaseed -2 0)
+	(morphjulia 2 0)
+	(usleep 2000000)
+
+And following is the "rotozooming" animation::
+
+	(initstate)
+	(fastrotate #t)
+	(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08 9.69332308834E-08)
+	(morphangle 300)
+	(usleep 10000000)
+	(wait)
+	(fastrotate #f)

+    this License; they are outside its scope. The act of running the Program is not
+    restricted, and the output from the Program is covered only if its contents
+    constitute a work based on the Program (independent of having been made by
+    running the Program). Whether that is true depends on what the Program does.
+
+2.  You may copy and distribute verbatim copies of the Program's source code as you
+    receive it, in any medium, provided that you conspicuously and appropriately
+    publish on each copy an appropriate copyright notice and disclaimer of warranty;
+    keep intact all the notices that refer to this License and to the absence of any
+    warranty; and give any other recipients of the Program a copy of this License
+    along with the Program.
+
+    You may charge a fee for the physical act of transferring a copy, and you may at
+    your option offer warranty protection in exchange for a fee.
+
+3.  You may modify your copy or copies of the Program or any portion of it, thus
+    forming a work based on the Program, and copy and distribute such modifications
+    or work under the terms of Section 1 above, provided that you also meet all of
+    these conditions:
+
+    a.  You must cause the modified files to carry prominent notices stating that
+        you changed the files and the date of any change.
+
+    b.  You must cause any work that you distribute or publish, that in whole or in
+        part contains or is derived from the Program or any part thereof, to be
+        licensed as a whole at no charge to all third parties under the terms of
+        this License.
+
+    c.  If the modified program normally reads commands interactively when run, you
+        must cause it, when started running for such interactive use in the most
+        ordinary way, to print or display an announcement including an appropriate
+        copyright notice and a notice that there is no warranty (or else, saying
+        that you provide a warranty) and that users may redistribute the program
+        under these conditions, and telling the user how to view a copy of this
+        License. (Exception: if the Program itself is interactive but does not
+        normally print such an announcement, your work based on the Program is not
+        required to print an announcement.)
+
+    These requirements apply to the modified work as a whole. If identifiable
+    sections of that work are not derived from the Program, and can be reasonably
+    considered independent and separate works in themselves, then this License, and
+    its terms, do not apply to those sections when you distribute them as separate
+    works. But when you distribute the same sections as part of a whole which is a
+    work based on the Program, the distribution of the whole must be on the terms of
+    this License, whose permissions for other licensees extend to the entire whole,
+    and thus to each and every part regardless of who wrote it.
+
+    Thus, it is not the intent of this section to claim rights or contest your
+    rights to work written entirely by you; rather, the intent is to exercise the
+    right to control the distribution of derivative or collective works based on the
+    Program.
+
+    In addition, mere aggregation of another work not based on the Program with the
+    Program (or with a work based on the Program) on a volume of a storage or
+    distribution medium does not bring the other work under the scope of this
+    License.
+
+4.  You may copy and distribute the Program (or a work based on it, under Section 2)
+    in object code or executable form under the terms of Sections 1 and 2 above
+    provided that you also do one of the following:
+
+    a.  Accompany it with the complete corresponding machine-readable source code,
+        which must be distributed under the terms of Sections 1 and 2 above on a
+        medium customarily used for software interchange; or,
+
+    b.  Accompany it with a written offer, valid for at least three years, to give
+        any third party, for a charge no more than your cost of physically
+        performing source distribution, a complete machine-readable copy of the
+        corresponding source code, to be distributed under the terms of Sections 1
+        and 2 above on a medium customarily used for software interchange; or,
+
+    c.  Accompany it with the information you received as to the offer to distribute
+        corresponding source code. (This alternative is allowed only for
+        noncommercial distribution and only if you received the program in object
+        code or executable form with such an offer, in accord with Subsection b
+        above.)
+
+    The source code for a work means the preferred form of the work for making
+    modifications to it. For an executable work, complete source code means all the
+    source code for all modules it contains, plus any associated interface
+    definition files, plus the scripts used to control compilation and installation
+    of the executable. However, as a special exception, the source code distributed
+    need not include anything that is normally distributed (in either source or
+    binary form) with the major components (compiler, kernel, and so on) of the
+    operating system on which the executable runs, unless that component itself
+    accompanies the executable.
+
+    If distribution of executable or object code is made by offering access to copy
+    from a designated place, then offering equivalent access to copy the source code
+    from the same place counts as distribution of the source code, even though third
+    parties are not compelled to copy the source along with the object code.
+
+5.  You may not copy, modify, sublicense, or distribute the Program except as
+    expressly provided under this License. Any attempt otherwise to copy, modify,
+    sublicense or distribute the Program is void, and will automatically terminate
+    your rights under this License. However, parties who have received copies, or
+    rights, from you under this License will not have their licenses terminated so
+    long as such parties remain in full compliance.
+
+6.  You are not required to accept this License, since you have not signed it.
+    However, nothing else grants you permission to modify or distribute the Program
+    or its derivative works. These actions are prohibited by law if you do not
+    accept this License. Therefore, by modifying or distributing the Program (or any
+    work based on the Program), you indicate your acceptance of this License to do
+    so, and all its terms and conditions for copying, distributing or modifying the
+    Program or works based on it.
+
+7.  Each time you redistribute the Program (or any work based on the Program), the
+    recipient automatically receives a license from the original licensor to copy,
+    distribute or modify the Program subject to these terms and conditions. You may
+    not impose any further restrictions on the recipients' exercise of the rights
+    granted herein. You are not responsible for enforcing compliance by third
+    parties to this License.
+
+8.  If, as a consequence of a court judgment or allegation of patent infringement or
+    for any other reason (not limited to patent issues), conditions are imposed on
+    you (whether by court order, agreement or otherwise) that contradict the
+    conditions of this License, they do not excuse you from the conditions of this
+    License. If you cannot distribute so as to satisfy simultaneously your
+    obligations under this License and any other pertinent obligations, then as a
+    consequence you may not distribute the Program at all. For example, if a patent
+    license would not permit royalty-free redistribution of the Program by all those
+    who receive copies directly or indirectly through you, then the only way you
+    could satisfy both it and this License would be to refrain entirely from
+    distribution of the Program.
+
+    If any portion of this section is held invalid or unenforceable under any
+    particular circumstance, the balance of the section is intended to apply and the
+    section as a whole is intended to apply in other circumstances.
+
+    It is not the purpose of this section to induce you to infringe any patents or
+    other property right claims or to contest validity of any such claims; this
+    section has the sole purpose of protecting the integrity of the free software
+    distribution system, which is implemented by public license practices. Many
+    people have made generous contributions to the wide range of software
+    distributed through that system in reliance on consistent application of that
+    system; it is up to the author/donor to decide if he or she is willing to
+    distribute software through any other system and a licensee cannot impose that
+    choice.
+
+    This section is intended to make thoroughly clear what is believed to be a
+    consequence of the rest of this License.
+
+9.  If the distribution and/or use of the Program is restricted in certain countries
+    either by patents or by copyrighted interfaces, the original copyright holder
+    who places the Program under this License may add an explicit geographical
+    distribution limitation excluding those countries, so that distribution is
+    permitted only in or among countries not thus excluded. In such case, this
+    License incorporates the limitation as if written in the body of this License.
+
+10. The Free Software Foundation may publish revised and/or new versions of the
+    General Public License from time to time. Such new versions will be similar in
+    spirit to the present version, but may differ in detail to address new problems
+    or concerns.
+
+    Each version is given a distinguishing version number. If the Program specifies
+    a version number of this License which applies to it and “any later version�,
+    you have the option of following the terms and conditions either of that version
+    or of any later version published by the Free Software Foundation. If the
+    Program does not specify a version number of this License, you may choose any
+    version ever published by the Free Software Foundation.
+
+11. If you wish to incorporate parts of the Program into other free programs whose
+    distribution conditions are different, write to the author to ask for
+    permission. For software which is copyrighted by the Free Software Foundation,
+    write to the Free Software Foundation; we sometimes make exceptions for this.
+    Our decision will be guided by the two goals of preserving the free status of
+    all derivatives of our free software and of promoting the sharing and reuse of
+    software generally.
+
+12. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE
+    PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED
+    IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS
+    IS� WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
+    NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
+    PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+    PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+    ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+13. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
+    COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE
+    PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,
+    SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY
+    TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+    RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+    PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+Appendix: How to Apply These Terms to Your New Programs
+```````````````````````````````````````````````````````
+
+If you develop a new program, and you want it to be of the greatest possible use to
+the public, the best way to achieve this is to make it free software which everyone
+can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach them
+to the start of each source file to most effectively convey the exclusion of
+warranty; and each file should have at least the “copyright� line and a pointer to
+where the full notice is found.
+
+::
+
+    
+         one line to give the program's name and a brief idea of what it does.
+         Copyright (C) yyyy  name of author
+         
+         This program is free software; you can redistribute it and/or modify
+         it under the terms of the GNU General Public License as published by
+         the Free Software Foundation; either version 2 of the License, or
+         (at your option) any later version.
+         
+         This program is distributed in the hope that it will be useful,
+         but WITHOUT ANY WARRANTY; without even the implied warranty of
+         MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+         GNU General Public License for more details.
+         
+         You should have received a copy of the GNU General Public License
+         along with this program; if not, write to the Free Software
+         Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA.
+    
+..
+
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this when it
+starts in an interactive mode:
+
+::
+
+    
+         Gnomovision version 69, Copyright (C) year name of author
+         Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
+         This is free software, and you are welcome to redistribute it
+         under certain conditions; type 'show c' for details.
+    
+..
+
+
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate parts of
+the General Public License. Of course, the commands you use may be called something
+other than 'show w' and 'show c'; they could even be mouse-clicks or menu
+items—whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your school, if
+any, to sign a “copyright disclaimer� for the program, if necessary. Here is a
+sample; alter the names:
+
+::
+
+    
+         Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+         'Gnomovision' (which makes passes at compilers) written by James Hacker.
+         
+         signature of Ty Coon, 1 April 1989
+         Ty Coon, President of Vice
+    
+..
+
+
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may consider it
+more useful to permit linking proprietary applications with the library. If this is
+what you want to do, use the GNU Lesser General Public License instead of this
+License.

+Inside coloring mode
+====================
+
+**Syntax**:(incoloring integer)
+
+Areas inside the set are usually filled in black, but this is only a
+convention; you could color them in differently to make the fractal look more
+interesting. The only method available to make areas inside the set visible is
+to display the value of the latest orbit as the value of each pixel.
+
+The :tutor:`tutorial on incoloring <incolor.xaf>` has more information
+and examples.
+
+XaoS has many different ways to show that value. The cryptic names of the modes
+are mathematical formulae, where **real** means the real part of the latest
+orbit, and **imag** means the imaginary part. **zmag** uses the magnitude of
+the value. The **Decomposition-like** method uses the angle of the orbit. Also,
+:ref:`truecolor <tcolor>` incoloring modes are available, that display one
+value in each of the red, blue and green color planes (or, for some modes, in
+each of the hue, saturation and value planes). In the scripting language, the
+incoloring mode is specified by one of the following integers:
+
+0

+Line drawing functions
+======================
+
+XaoS has support for drawing lines. These functions are available only in
+animations and could be used to show some parts of fractals or draw simple
+diagrams. See the tutorial ":tutor:`Introduction to fractals <intro.xaf>`" for examples of this feature.
+
+Lines can be drawn in **screen** coordinates, where 0,0 is the top left corner
+and 1,1 is bottom right, **scaled** coordinates, which are similar, but scaled
+to keep 0,0--1,1 rectangular, or **Fractal** coordinates, to draw a line at an
+exact position on the screen.
+
+The color of the line should be specified by the :ref:`color <color>` command.
+You might draw an arbitrary number of lines and, later, morph them. Each line
+is identified by a unique numeric key; the current key can be set using
+linekey. Commands for changing lines operate on the line with the current key.
+(Lines drawn in sequence have consecutive numbers.)
+
+For example::
+
+	(color 'red) 
+	(line 'scaled 0.3 0.5 0.7 0.5) 
+	(line 'scaled 0.3 0.5 0.7 0.5)

+Iterations
+==========
+
+**Syntax**:(maxiter integer)
+
+When the fractal set is calculated, a orbital trajectory is examined for each
+point. If the orbit diverges to infinity, the point is outside the set.
+Otherwise, the point is inside the set. For exact calculations, you need to
+know the entire orbital trajectory, which is infinitely long for areas inside
+the set, so fractals cannot be calculated exactly. By default, XaoS calculates
+at most 170 positions (iterations) and then gives up; if the point is still
+inside the bail-out value, it guesses that the point is inside the set.
+
+When zoomed into a detailed area, especially one close to the set boundary,
+this value could become too low, and the fractal will become boring. You might
+try increasing this value if you want to get the image interesting again; but
+this necessarily slows down the calculation at the same time.
+
+The tutorial chapter ":tutor:`Escape time fractals <escape.xaf>`" has
+more information on fractal calculation in XaoS, and there is a lengthy section
+in the hacker's manual (xaosdev.texinfo) devoted to the subject.

+=====================
+
+**Syntax**:(outcoloring integer)
+
+Outcoloring modes are similar to :ref:`incoloring modes <incoloring>`, but
+indicate how to display the areas outside the set instead. As with incoloring
+modes, the value of the latest orbit can be used to determine the color of each
+pixel, but the default is to use the number of iterations needed for the value
+at that point to become recognisably divergent as the color.
+
+The :tutor:`tutorial on outcoloring <outcolor.xaf>` has more information
+and examples.
+
+The cryptic names of the modes are mathematical formulae, where **iter** means
+the number of iterations required for the value to become recognisably
+divergent, **real** means the real part of the latest orbit, and **imag** means
+the imaginary part. **binary decomposition** uses a different color when the
+imaginary part of the orbit is lower than zero, and **smooth** attempts to
+remove stripes and discontinuities. Also, :ref:`truecolor <tcolor>` outcoloring
+modes are available, that display one value in each of the red, blue and green
+color planes (or, for some modes, in each of the hue, saturation and value
+planes).
+
+In the scripting language, the outcoloring mode is specified by one of the
+following integers:
+
+0
+
+    iter (default)
+
+1
+
+    iter+real
+
+2
+

+
+Periodicity checking
+====================
+
+**Syntax**:(periodicity bool)
+
+Periodicity checking is one way to speed up the calculation. Areas inside the
+set always need :ref:`maxiter <maxiter>` iterations to determine that the point
+is probably inside the set (while it is rare for areas outside to need anywhere
+near that much). Often the orbital trajectory falls into a periodic, repeating
+cycle; if that can be detected, the calculation can be stopped early, as
+there's no way that the orbit can ever leave the cycle again (hence it cannot
+diverge, hence the point must be inside the set).
+
+Implementing this method efficiently is quite problematic. It slows down the
+cases where cycles are not found, because cycle-checking is quite hard work and
+has to take place for all points, even those that don't become cyclic. Because
+of the inexactness of floating-point calculations, the cycles are never exact,
+so you need to use an error value. Higher error values mean that cycles will be
+detected sooner, while lower error values increase the exactness of the
+calculation. Higher values can introduce serious errors, especially at the
+front of the Mandelbrot set. XaoS detects this automatically and corrects for
+it in most cases, but sometimes it might be wrong. Also, other optimizations in
+XaoS (such as boundary tracing) don't give this method much of a chance to run,
+since areas inside the set are usually not calculated at all.
+
+That's why the advantages of this optimization are questionable. You should
+probably experiment with enabling and disabling it. Sometimes XaoS is faster
+with this enabled, sometimes when disabled. Also, this method works only when
+:ref:`incoloring <incoloring>` methods are disabled, and only for some fractal
+types (some fractal types, e.g. newton, don't have any concept of an area
+'inside the set' at all.)
+
+The tutorial chapter ":tutor:`Escape time fractals <escape.xaf>`" has
+more information on fractal calculation in XaoS, and there is a lengthy section
+in the hacker's manual (xaosdev.texinfo) devoted to the subject.

+Plane
+=====
+
+**Syntax**:(plane integer)
+
+All fractals displayed by XaoS are functions with a complex parameter. They can
+be be displayed in the normal complex plane where the x coordinate is the real
+part of the number and the y is imaginary; but they can also be displayed
+differently:
+
+mu
+
+    Normal complex plane (default)
+
+1/mu
+
+    Inversion--infinity is at 0 and 0 is at infinity.
+
+1/(mu+0.25)
+
+    Similar to inversion, but moves the center outside the Mandelbrot set, so
+    it looks parabolic.
+
+lambda plane, 1/lambda, 1/lambda-1
+
+    Lambda plane and its inversion, and with a different center.
+
+1/(mu-1.40115)
+
+    A very interesting mode for the Mandelbrot set, this makes small things
+    large, for easier browsing of the set's details.
+
+The :tutor:`tutorial about planes <plane.xaf>` has some examples.
+
+In the scripting language, the planes are numbered as follows:
+
+0
+
+    mu
+
+1
+
+    1/mu
+
+2
+
+    1/(mu+0.25)

+Image rotation
+==============
+
+XaoS has support for rotation of the image to any angle. By default, changing
+the angle requires recalculation of the whole screen, but when **fast rotation
+mode** is enabled, the angle can be changed smoothly. In this mode XaoS
+calculates a larger non-rotated image and rotates it when needed, so it
+increases memory requirements and slows XaoS down; hence, it should be disabled
+when rotation is not being used.
+
+The user interface provides two rotation modes--**rotate by mouse** which
+allows the angle to be changed by dragging with the first mouse button
+depressed, and **continuous rotation mode**, where the image is rotated
+clockwise continuously, and the arrow keys can be used to change the rotiation
+speed.
+

+
+Random dot stereogram
+=====================
+
+Fractal images are good as a base for random dot stereograms. In case you don't
+know what these are, please point your browser to Google or another search
+engine and find some articles about such images, because learning to read such
+images takes some effort. They make it possible to generate three dimensional
+images on a normal monitor without any additional hardware, by exploiting bugs
+in the human brain (although you need two working eyes, and some people never
+learn to see them; they can simply ignore this feature).
+
+XaoS is able to generate these images in animations, so you may use all normal
+XaoS functions (except palette changing and palette rotation, which makes no
+sense applied to a stereogram). To make the animation yet more exciting, XaoS
+emulates "falling" into the set; while you zoom in, your distance from the set
+drops and drops--but you never hit it; when the set reaches the level of your
+monitor, the distance is changed again so you are far away.
+
+To make this work right, XaoS needs to know the **exact size of your monitor**.
+Because most platforms have no way to determine this, you need to use **command
+line options** to tune it. If it's not set or is wrong, the stereograms will
+probably be impossible to see (if your monitor is too big or resolution too
+low), or the images will seem to be shallow (if your monitor is too small or
+resolution too high).
+
+By default XaoS expects my 15" monitor (29.0cm x 21.5 cm). Another cause of
+problems is the virtual screen supported by some windowed environments (like
+some X servers) that makes a program think that the resolution is higher than
+it actually is, and you see only part of this extra-large screen.
+
+The worst thing you could possibly do is to run full-screen XaoS in some
+graphical windowing system (OS/2 on top of Windows or Wine on top of Linux,
+perhaps) where XaoS can't tell the real size of its window at all. In such
+cases, it's normally better (not to mention faster) to run XaoS natively,
+rather than under such an emulation layer.
+
+The following command line options are provided to specify sizes:
+
+-screenwidth, -screenheight
+
+    Lets you specify the size of your screen in centimeters. Note that you need
+    to specify the size of the visible image on the monitor, not the size with
+    edge borders, or the size of the tube. The simplistic 'my monitor is 17",
+    just turn 17" into centimeters' doesn't work; that 17" is a marketing
+    figure and has only a vague connection to reality. Get out a ruler and
+    measure it.
+
+-pixelwidth, -pixelheight
+
+    Lets you specify the exact size of a single pixel, if XaoS cannot determine
+    this for itself from your screen size.
+
+These options are used by some other parts of XaoS as well, so you should use
+them even when you don't want to see stereograms. You should probably write a
+small starting script (or alias, or shortcut; whatever your environment uses)
+that passes the correct parameters to XaoS.
+
+If the window is **smaller than 8cm in any direction**, you will probably be
+unable to see anything; make the window bigger. The correct way to see XaoS
+stereograms is:
+
+1
+
+    Start XaoS with options specifying the exact size of your screen or one
+    pixel on it
+
+2
+
+    Sit 60cm away from monitor
+
+3
+
+    If you use a windowed environment, resize XaoS's window to make it wider
+    than, say, 15 cm.
+
+4
+
+    Enable the filter (by pressing E)
+
+5
+
+    focus on a point far away from the monitor (try to use your own reflection,
+    if your monitor's not antireflective); the random blurring should
+    eventually fall into the pattern of a Mandelbrot set.
+
+6
+
+    Carefully use your mouse to zoom into interesting areas (it is easy to lose
+    concentration when you are not trained; but you can use the autopilot...)
+
+7
+
+    Enjoy animation :)
+
+If you still can't see the stereograms, it could be that the fractal, or your
+eye, is deformed. A deformed fractal can be caused by your specifying your
+monitor size wrongly. Visual problems that damage depth perception, as well as
+problems like astigmatism, can make it impossible to see stereograms at all.

+Truecolor coloring mode
+=======================
+
+**Syntax**:(intcoloring integer)
+
+**Syntax**:(outtcoloring integer)
+
+Truecolor coloring modes are similar to :ref:`incolor <incoloring>` and
+:ref:`outcolor <outcoloring>` coloring modes; but instead of using a palette,
+they directly calculate the red, green and blue components of the color. This
+lets you display more parameters at once, and produces interesting and often
+attractive results. On 8bpp displays you need to enable the :ref:`palette
+emulator filter <palettef>` first to see anything, amd the quality won't be so
+good, as far fewer colors are available per parameter.
+
+The :tutor:`tutorial on truecolor coloring modes <truecol.xaf>` has more
+information and examples.
+
+The cryptic names of the modes are always three mathematical formulae (one for
+each color component), where **real** means the real part of the latest orbit,
+and **imag** means the imaginary part.
+
+To enable inside/outside truecolor coloring mode in the scripting language, set
+incoloring/outcoloring value to 10 (truecolor coloring mode) before (or after)
+calling intcoloring or outtcoloring.
+
+In the scripting language, the coloring mode is specified by one of the
+following integers:
+

+    black

+
+Feature Overview
+================
+
+This is a brief introduction to the basic XaoS features.
+
+How to zoom
+-----------
+
+The main advantage of XaoS is that after a few seconds' delay to calculate the
+first image, you may choose any point with the mouse and press the **left**
+button. The image will start to zoom smoothly into the point you choose. You
+may move the mouse and zoom smoothly into interesting areas. By pressing the
+**middle button** (or **left+right** buttons) you may also **move the image**
+using "drag & drop" if you missed an interesting place. **Unzooming** is also
+possible by using the **right button**, but it is much slower because
+optimizations are not so effective as for zooming.
+
+In case you think that the default **speed** is boring (it is quite slow, to
+make XaoS smooth on a slow computer) you may change it by pressing **arrow
+up/down**. But faster zooming is more expensive, so if the speed is too high
+you will see little but funny colorful blinking rectangles.
+
+Autopilot
+---------
+
+To make XaoS yet more impressive we made a special autopilot that automatically
+drives into interesting boundaries of the set. So you can press A, play your
+favorite music, drink coffee and relax. I never tried this but it should be
+really relaxing! Many pictures in the XaoS gallery were discovered using the
+autopilot.
+
+The autopilot also has some additional features. It turns back when the zoomed
+picture stops being interesting, and is able to spot when it's zoomed into a
+really boring part (or has reached the limit of floating point numbers) and
+restart zooming from the top.
+
+Various fractal formulae
+------------------------
+
+XaoS also supports formulae other than the Mandelbrot set. You may change
+**formula** using the **number keys** or **SHIFT+letters**.
+
+On keys 1 to 5 are **Mandelbrot sets of various power**. The "normal"
+Mandelbrot set is on key 1.
+
+On key 6 is a fractal called **Newton**. It is Newton's famous formula for
+finding roots.
+
+On key 7 is the **fourth ordered Newton** fractal.
+
+On key 8 is a fractal called **Barnsley**.
+
+On key 9 is **Barnsley's second** fractal.
+
+On key 0 is **Barnsley's third** fractal.
+
+With keys SHIFT-A you can display a fractal called **octo**. It is a fractal
+that Thomas discovered in fractint.
+
+With keys SHIFT-B you can display a fractal called **Phoenix**. It is a very
+nice and quite famous fractal.
+
+With keys SHIFT-C you can display a fractal called **Magnet**. This fractal has
+quite a complex formula so it is a bit slow.
+
+With keys SHIFT-D you can display the **Magnet2** fractal.
+
+The rest of the built-in fractals are accessible through an other menu, but you
+can still use the hotkeys.
+
+On SHIFT-E is a fractal called **Triceratops** found by Arpad.
+
+On SHIFT-F is a fractal called **Catseye** found by Arpad. This is more
+interesting if you change the bailout value.
+
+On SHIFT-G is a fractal called **Mandelbar**. It was in Gnofract4d, and they
+found it at: http://mathworld.wolfram.com/MandelbarSet.html
+
+On SHIFT-H is the **Lambda** fractal.
+
+On SHIFT-I and SHIFT-J are the **Manowar** and **Spider** fractals, they were
+found by users of fractint. (Scott Taylor or Lee Skinner) It was on
+http://spanky.triumf.ca/www/fractint/ taylor_skinner_type.html
+
+The next 3 fractals are famous classic fractals.
+
+On SHIFT-K is the **Sierpinski** Gasket. You can change its shape by selecting
+another Julia seed. (This is for technical reasons.)
+
+On SHIFT-L is the **Sierpinski Carpet.** It's shape can also be changed by
+selecting another Julia seed.
+
+On SHIFT-M is the **Koch Snowflake.**
+
+Out-coloring modes
+------------------
+
+To make fractals yet more interesting, more coloring modes for points outside
+the set are provided. "Classical coloring mode" uses the number of iterations
+that the orbit required to escape to (nearly) infinity. You can change this
+mode from the **Fractal menu** or by pressing key C To see more about coloring
+modes, try the tutorial on :tutor:`Incoloring modes <incolor.xaf>` from
+the XaoS features overview.
+
+Those cryptic names for coloring modes are mathematical formulae, where
+**iter** means number of iterations, **real** means real coordinate of last
+orbit, and **imag** means imaginary coordinate of last orbit.
+
+In-coloring mode
+----------------
+
+In-coloring mode is similar to out-coloring, except that it changes how things
+inside the set are displayed. This can also be changed from the **fractal
+menu** or by pressing F.
+
+You might also want to see the tutorial on :tutor:`Out-coloring modes <outcolor.xaf>` from the XaoS features overview.
+
+Planes
+------
+
+All fractals displayed by XaoS are functions with a complex parameter. It can
+be displayed in the normal complex plane, where x is the real part of the
+number, and y is the imaginary part; but it can also be displayed in a number
+of other planes. You can select the plane to use from the **Fractal menu**, or
+by pressing I.
+
+Like the coloring modes, planes have cryptic names. You guessed it, they're
+mathematical formulae. Here mu means coordinates in the normal complex plane.
+If you have coordinates in 1/mu plane, and you need coordinates in the a
+complex plane (to calculate the Mandelbrot set) you simply use the coordinates
+as mu. Lambda is another plane that can be converted to mu using a similar
+formula.
+
+mu
+
+    normal mode.
+
+1/mu
+
+    Inversion: infinity goes to 0 and 0 goes to infinity.
+
+1/(mu+0.25)
+
+    Similar to inversion, but moves the center outside of the Mandelbrot set so
+    that it looks parabolic.
+
+lambda
+
+    Lambda plane.
+
+1/lambda
+
+    Inversion of lambda plane.
+
+1/lambda-1
+
+    Inversion with moved center.
+
+1/(mu-1.40115)
+
+    A very interesting mode for the Mandelbrot set. It makes small things big,
+    so you can browse the set's details easily.
+
+Mandelbrot/Julia switching
+--------------------------
+
+Most of the fractals displayed by XaoS (currently all of them) have two forms:
+Mandelbrot and Julia. Every point in a Mandelbrot set has its own Julia set. To
+see more about this correspondence, try the tutorial on :tutor:`Julia set <julia.xaf>` from the Introduction to fractals.
+
+In the Mandelbrot mode, you can get a corresponding Julia by moving the mouse
+to an interesting point and pressing M. To get back press M again. Some
+fractals (Barnsley and phoenix) are already in their Julia versions, because
+the Mandelbrot ones are boring. But by pressing M in such fractal you should
+get the Mandelbrot version, and by choosing another point as the base point and
+pressing M again you should get a completely different fractal. The most
+interesting points for Julia sets are at the boundaries of the Mandelbrot set.
+Most of the Julias inside or outside the set are boring.
+
+Fast Julia preview mode
+-----------------------
+
+Fast Julia mode is a quick way to find a point to use as a base for the Julia
+set.. Just press J and a small Julia set will be displayed in the top left
+corner. Then move the mouse around with button 1 depressed, and the Julia for
+the point the mouse is over will be automatically generated.
+
+Palette
+-------
+
+If you think that the default XaoS colors are ugly or you are just bored by
+them you can change it by pressing P. XaoS will automatically generate random
+palettes. Many of them look ugly, so press P again to get another one until you
+find one you like.
+
+Filters
+-------
+
+Many interesting effects are done by post-calculation :ref:`filters <filter>`.
+XaoS has filters that do everything from embossing, through motion-blurring,
+right through to turning the fractal into a stereogram. To enable them use the
+filter menu or press E.
+
+Palette cycling
+---------------
+
+This is a very old trick that makes the Mandelbrot set a little flashier. You
+may enable or disable it using Y. In the truecolor modes you need to enable the
+:ref:`palette emulator filter <palettef>` first. This is done via the E key, or
+from the filter menu.
+
+Changing number of iterations
+-----------------------------
+
+To calculate fractals perfectly, you need an infinite number of iterations.
+XaoS does just the first few of them, so after lots of zooming you may get into
+a place that looks quite boring, and the boundaries of the set are rounded,
+without any interesting details. This can be changed by changing the number of
+iterations:
+
+Press and hold arrow right and wait until iterations are high enough. This may
+slow down calculation much. To reduce number of iterations press arrow left.
+
+Changing resolution
+-------------------
+
+XaoS usually starts in a low resolution (320x200 or thereabouts) to make
+calculations faster. If you have a fast computer or you need to save bigger
+.gif images, you may change the resolution. This can be done by pressing = in
+the full screen drivers, or simply by resizing the XaoS window.
+
+Changing driver
+---------------
+
+XaoS usually has more than one driver available. You may change it on the fly
+in case you want a different one. For example, XaoS started in X11 can be
+switched at runtime to use the AA driver. This can be done from the UI menu.
+
+This action is bit dangerous, because XaoS can crash during initialization if
+there is some problem with initialization; XaoS tries to initialize a new
+driver, and if it fails it attempts to return back to the original. Sometimes
+this is impossible, and all XaoS can do is terminate..
+
+Other features
+--------------
+
+XaoS has many other features, but they don't fit into this tutorial. Most of
+them are available from the menu, so you can experiment with them. You might
+also want to see the **animated tutorials** from the **help menu**, to have an
+idea what XaoS can do.

+Mandelbrot/Julia mode
+=====================
+
+Most fractals rendered by XaoS can be represented as Mandelbrot sets or Julias.
+Each point in the Mandelbrot set has its own Julia set. To learn more about
+this correspondence, see the tutorial on the :tutor:`Julia set <julia.xaf>`.
+
+This function switches between Mandelbrot and Julia representations. When
+switching to Julia, you need to set the seed--a point selected from the
+Mandelbrot set.
+
+If you run this function from the menu, you are prompted for the Julia seed as
+a number. Often, this can be clumsy, and it would be easier to specify a point
+with the mouse pointer. If you hit the M key instead of using the menu, the
+current mouse position is used.
+
+Good seedpoints lie at the boundaries of the Mandelbrot set; other seeds
+usually generate quite a boring fractal. You can also explore various seeds at
+high speed using the :ref:`Fast Julia mode <fastjulia>`.
+
+Not all fractals have Julias, but XaoS can generate fake Julia sets for those
+that do not, which use some Julia-like modification of the formula; so this
+function is currently usable for all fractal types.

+Perturbation
+============
+
+Perturbation is a simple trick which changes the point at which orbits start.
+Traditionally zero is used, but other values can generate interesting results
+too.
+
+On enabling this function from the menu, you will be asked for a complex number
+specifying the perturbation. It is a toggle; selecting it again resets the
+perturbation to zero without prompting.
+
+It can be used to specify a complex number representing a point on the screen.
+If you hit the B key instead of using the menu, the current mouse position is
+used. This too is a toggle, so B again will disable perturbation by setting it
+to zero.
+
+This function only has an effect for certain formulae (like the
+:ref:`Mandelbrot set <mandel>`) and only then in :ref:`Mandelbrot mode
+<uimandelbrot>`.
+
+**Available as**: menu item
+

+of toggling, you always specify the perturbation to use. Use 0 0 to disable

+====
+
+Set your current viewpoint in the fractal. This function is useful when you
+have found some interesting coordinates somewhere (on a web page, perhaps) and
+you want to see that position in XaoS.
+
+In the dialog you will be asked for the **center**, **radius** and **angle** of
+the image.
+
+The center specifies the point which is displayed at the center of the screen.
+The radius is the radius of a circle around this point; XaoS will size the
+image so that this circle only just fits on the screen. The angle gives the
+rotation of the image in degrees.
+
+People specify fractal coordinates in many ways. Some people use the
+coordinates of the upper-left and lower-right visible points, specifying the
+coordinates as four numbers x1, y1, x2, y2. To set the same viewpoint in XaoS,
+set the real portion of the center to (x1+x2)/2, the imaginary part of center
+to (y1+y2)/2, and the radius to the greater of x2-x1 and y2-y1.
+
+Other programs use a zoom factor instead of a radius. For these, you can set
+the radius to 2/zoom.
+
+**Available as**: menu item
+
+**Syntax**:(view float float float float)
+
+This function is used to set the visible area of fractal in animation files. It
+doesn't let let you specify the angle, (for that, see the separate function
+angle), but lets you specify an ellipse instead of a circle. You can specify
+both a real and an imaginary radius, so you have better control over the area
+that will be visible. XaoS will size the image so that the ellipse only just
+fits on the screen.
+

+
+Encoding Videos
+===============
+
+To create a video, make and xaf file first (the easiest way to do this is to
+use the **record** function in the file menu). Then you need to render the
+animation. XaoS can output sequences of ordinary PNG images, that can later be
+used by a video encoder.
+
+Generating image sequences for video
+------------------------------------
+
+To generate an image sequence, choose **Render Animation** from the **Misc**
+menu. You can also use the following command on the command line:
+
+xaos -render [filename] -size 352x240 -antialiasing -renderframerate 24
+-basename [basename]
+
+**File to render** ([filename]) is the name of the xaf file, **Basename**
+([basename]) is the name used as the base filename for rendered images. This
+should also include the path where you want to save the images. XaoS adds a
+four digit sequence number and .png extension to this name automatically.
+
+You might also want to change the resolution. Make sure that the resolution you
+choose is supported by the video codec you wish to use.
+
+The framerate can also be altered. Make sure you choose a framerate that is
+supported by the video codec you wish to use.
+
+**Antialiasing** (-antialiasing) is used to produce anti-aliased images. It
+takes a much longer time and much more memory to calculate them, but resulting
+images are better for video compression and they result in a much smaller video
+file. (the same is true of **JPEG images**)
+
+On the other hand, the other XaoS rendering option **Always Recalculate**
+(-alwaysrecalc) (which disables XaoS's zooming optimizations) is **not
+recommended**. If that's used, the sequence of animation then contains quite a
+lot of extra information, which increases size of video file, but because of
+the codec's lossy compression it is hard to see any difference, so it's not
+worth it.
+
+Rendered files
+--------------
+
+Once you start it, XaoS will generate thousands of frames. They take quite a
+long time to calculate and save, and consume plenty of disk space. (e.g. to
+render part 1 of the tutorial you need about 60MB and half an hour of time).
+
+All images are named [basename]framenum.png. For example intro0001.png is the
+first frame of the animation intro. If consecutive frames are the same, XaoS
+doesn't save them, so some frames may be missing. If your encoder can't handle
+that, you will need to write a simple script which will fill in the gaps by
+means of mv or symbolic linking.
+
+A list of all filenames is saved into the file [basename].par, where each line
+is the name of one frame. The names repeat here if necessary, so you can use
+this file to supply filenames to the encoder.
+
+Encoding videos
+---------------
+
+Once XaoS has generated the png files for each frame of the animation, you can
+use a third-party video encoder to convert the sequence of images into a video
+file. We currently recommend the following encoders, which support a wide
+variety of video codecs and file formats:
+
+ffmpeg
+
+* `ffmpeg home page`_
+* `ffmpeg instructions`_
+
+.. _`ffmpeg home page`:
+	http://ffmpeg.mplayerhq.hu/ 
+
+.. _`ffmpeg Instructions`:

+
+These are both command line tools. If you prefer a graphical tool, you may
+prefer `Quicktime Pro`_ from Apple. However, this software costs approximately 
+US $30. Although QuickTime may be easier to use, the two free
+encoders above are just as capable once you learn how to use them.

+Zooming functions
+=================
+
+The functions for zooming/unzooming were created mainly for recording
+animations. In manually created animation files, it is easier to use
+:ref:`morphview <morphview>`.
+
+**Syntax**:(zoomcenter complex) This function sets the center to zoom in on.
+The center is given as a position in fractal coordinates.
+
+**Available as**: command
+
+**Syntax**:(zoom) Start zooming to the area specified by zoomcenter.
+
+The speed of zooming should be controlled by the function :ref:`speed <speed>`
+or in a more exact way by maxstep and speedup.
+
+**Syntax**:(unzoom)
+
+Start unzooming from the area specified by zoomcenter.
+
+**Available as**: command
+
+**Syntax**:(stop) Stop zooming or unzooming.

+
+<head>Users' Discussion Group</head>
+Site: <tt>http://groups.google.com/group/xaos-users</tt><p>
+
+The xaos-users discussion group on Google Groups provides a place for XaoS 
+users to help each other get the most out of XaoS. XaoS developers also 
+monitor this discussion and answer questions from time to time.<p>
+
+You can browse the archives freely but you must join the group in order to 
+post. However, Google Groups provides a range of options for participation 
+from a traditional mailing list to a completely web-based forum, so you 
+don't have to get emails if you don't want to.<p>
+
+If you have a question or problem, please feel free to ask for help. We 
+also encourage you to share examples (.xaf or .xpf files), hints and 
+tips. If you have a gallery of images created using XaoS, feel free to 
+post a link to the group.
+
+
+<head>Developers' Discussion Group</head>
+
+Site: <tt>http://groups.google.com/group/xaos-devel</tt><p>
+
+The xaos-devel discussion group on Google Groups is where XaoS developers 
+discuss and coordinate the further development of XaoS. XaoS users are 
+welcome to monitor this forum as well, but general discussion and requests 
+for help should be posted to the Users' Discussion Group instead.
+
+
+<head>Issue Tracker</head>
+
+Site: <tt>http://code.google.com/p/gnuxaos/issues/list</tt><p>
+
+Issues are tracked on Google Code. If you think you have found a bug in 
+XaoS or have an idea for a great new feature, please let us know about it. 
+However, if you're not sure how to submit a useful issue report, please ask 
+on the xaos-users discussion group first (see above).<p>
+
+Please don't submit duplicate issues. Search the existing ones first to make 
+sure nobody has already reported it. You can add additional information about 
+a bug by entering a comment on an existing bug. You can also express your 
+interest in an issue by using the "Star" function on Google Code. This lets 
+the developers know how many users are interested in an issue and also allows 
+you receive status updates.<p>
+
+The developers will do their best to respond to issues in a timely manner. 
+However, keep in mind that XaoS is developed on a volunteer basis and the 
+developers work on it in their spare time. Therefore, we can't guarantee that 
+issues will be addressed in a certain timeframe.<p>
+
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%devel
+<head>Development</head>
+XaoS is free software. One of the most significant rights its <a gpl>license</a>
+grants to you is the right to <emph>freely get, study and improve</emph> its
+source code, which is available from the XaoS homepage.
+<p>
+XaoS has an open development model. All development is coordinated via Google Code
+at <tt>http://gnuxaos.googlecode.com/</tt>. Development versions are
+available via Subversion at <tt>https://sourceforge.net/scm/?type=svn&group_id=5771</tt>,
+so if you are interested in the future of XaoS, give the latest source a try! We also 
+have a several <a support>discussion groups</a>, which you can join if you want to 
+discuss XaoS with others or participate in the development process.
+<p>
+If you want to do some development, you are encouraged to send your work back
+to the <a about>authors</a>; if it is well done, it will be added to the
+next release. All changes should be submitted to the Google Code issue tracker.
+<p>
+XaoS is quite easily extensible. You might want to
+read a bit about its internals in the file <emph>doc/xaosdev.info</emph>.
+XaoS is also portable, so if it doesn't work on your favorite platform (or
+there is just an old version available), you could quite easily port it.
+<p>
+<head>Volunteer Opportunities</head>
+XaoS needs volunteers to make it the best fractal program it can be! 
+You don't have to be a programmer to help.  The following 
+tasks open to volunteers:
+
+<p>Improving the documentation via the Wiki (and improving the DokuWiki converter).
+<p>Compiling binaries for your favorite operating system.
+<p>Reviewing the source code, adding comments, and checking lines which generate warnings during compilation.
+<p>Creating additional tutorials and examples.
+<p>Translating XaoS into your language.
+<p>Implementing feature requests.
+<p>Fixing outstanding bugs.
+<p>If you would like to volunteer, join the discussion groups and let us know. We would be happy to help you get started!
+
+

+%sffe usrform usrformInit
+<head>Using user formulas</head>
+<p>
+XaoS supports entering your own custom formulas.
+Select <tt>User formula</tt> from the <tt>Fractal</tt> menu to define a 
+custom fractal formula.  Select <tt>User initialization</tt> to change 
+the sequence starting point <emph>z0</emph>. By default <emph>z0</emph> 
+is set to 0. User formulas should be interpreted as functions in the form<br>
+<emph>Z(n+1) = formula (Z(n), Z(n-1), C)</emph>.
+<p>
+In user formulas, as shown above, three variables are available:<br>
+<dl>
+<dt>z
+<dd>current sequance point Z(n)
+<dt>c
+<dd>current plane 'point'
+<dt>p
+<dd>previous sequence point Z(n-1)
+</dl>
+<p>
+Format for complex numbers is <emph>{re;im}</emph><br>
+eg. {3;2} is complex number 3+2i.
+<p>
+Available functions are listed below:
+<dl>
+<p>
+<dt>basic operations
+<dd>+, -, *, /
+<p>
+<dt>basic trigonometry
+<dd>sin, cos, tan, cot<br>
+asin, acos, atan, acot<br>
+sinh, cosh, tanh, coth
+<p>
+<dt>Exponential and logarithmic functions
+<dd>exp<br>
+log - natural logarithm<br>
+log2, log10<br>
+logN (base, z) - logarithm of base N (where N is integer)<br>
+logCN (base, z) - logarithm of base CN (where CN is complex)
+<p>
+<dt>power functions
+<dd>powi - power with integer exponent (fastest)<br>
+powd - power with real exponent<br>
+powdc - power with complex exponent<br>
+pow - same as powd<br>
+sqr - square
+<p>
+<dt>square functions
+<dd>sqrt - square root of a complex number<br>
+rtni (z, n, i) - i-th root of n-th orgder
+<p>
+<dt>other functions
+<dd>rand (max) - random real number in range [0, max)<br>

+%video
+
+<head>How to encode video files from XaoS</head>
+<p>
+To create a video, make and <tt>xaf</tt> file first (the easiest way to do this is
+to use the <emph>record</emph> function in the file menu). Then you need to render 
+the animation. XaoS can output sequences of ordinary <tt>PNG</tt> images, that
+can later be used by a video encoder.
+<p>
+<head>Generating image sequences for video</head>
+<p>
+To generate an image sequence, choose <emph>Render Animation</emph> from the <emph>Misc</emph>
+menu.  You can also use the following command on the command line:
+<p><tt>
+xaos -render [filename] -size 352x240 -antialiasing 
+       -renderframerate 24 -basename [basename]
+</tt><p>
+<emph>File to render</emph> (<tt>[filename]</tt>) is the name of the <tt>xaf</tt> file,
+<emph>Basename</emph> (<tt>[basename]</tt>) is the name used as the base filename for rendered images.  This should also include the path where you want to save the images.
+XaoS adds a four digit sequence number and <tt>.png</tt> extension to this name automatically.
+<p>
+You might also want to change the resolution. Make sure that the resolution
+you choose is supported by the video codec you wish to use.
+<p>
+The framerate can also be altered. Make sure you choose a framerate that is supported by
+the video codec you wish to use.
+<p>
+<emph>Antialiasing</emph> (<tt>-antialiasing</tt>) is used to produce anti-aliased images. 
+It takes a much longer
+time and much more memory to calculate them, but resulting images are better
+for video compression and they result in a much smaller video file.
+(the same is true of <emph>JPEG images</emph>)
+<p>
+On the other hand, the other XaoS rendering option <emph>Always Recalculate</emph> (<tt>-alwaysrecalc</tt>) (which disables
+XaoS's zooming optimizations) is <emph>not recommended</emph>. If that's used, the
+sequence of animation then contains quite a lot of extra information, which
+increases size of video file, but because of the codec's lossy compression it is hard
+to see any difference, so it's not worth it.
+<head>Rendered files</head>
+Once you start it, XaoS will generate thousands of frames. They take quite
+a long time to calculate and save, and consume plenty of disk space.
+(e.g. to render part 1 of the tutorial you need about 60MB and half an hour of time).
+<p>
+All images are named <tt>[basename]framenum.png</tt>. For example <tt>intro0001.png</tt> is
+the first frame of the animation intro. If consecutive frames are the same, XaoS
+doesn't save them, so some frames may be missing. If your encoder can't handle
+that, you will need to write a simple script which will fill in the gaps by means
+of <tt>mv</tt> or symbolic linking.
+<p>
+A list of all filenames is saved into the file <tt>[basename].par</tt>, where each line is
+the name of one frame. The names repeat here if necessary, so you can use this
+file to supply filenames to the encoder.
+<head>Encoding videos</head>
+Once XaoS has generated the png files for each frame of the animation, you
+can use a third-party video encoder to convert the sequence of images into
+a video file.  We currently recommend the following encoders, which support
+a wide variety of video codecs and file formats:
+<dl>
+<dt>ffmpeg
+<dd>Available from: <tt>http://ffmpeg.mplayerhq.hu/</tt><br>
+Instructions: <tt>http://ffmpeg.mplayerhq.hu/faq.html#SEC12</tt>
+<dt>mencoder
+<dd>Part of mplayer, available from: http://www.mplayerhq.hu/<br>
+Instructions: <tt>http://www.mplayerhq.hu/DOCS/HTML/en/menc-feat-enc-images.html</tt>
+</dl>
+These are both command line tools.  If you prefer a graphical tool, you may
+prefer Quicktime Pro from Apple (http://www.apple.com/quicktime/pro/). However,
+this software costs approximately US$30, and the authors of XaoS have no
+experience with it.  Although QuickTime may be easier to use, the two free 
+encoders above are just as capable once you learn how to use them.
+
+<p>
+Note: we used to recommend <a berkeley>Berkeley parallel MPEG encoder</a> to 
+encode the generated png files into MPEG videos.  We have kept 
+the instructions mainly for historic purposes.
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%berkeley
+<head>Berkeley parallel MPEG encoder</head>
+
+This is the encoder we used to recommend. However, it has not been updated
+for a very long time and no longer appears to compile on modern systems.
+Also, there are much more modern codecs available that provide better video
+quality and compression rates.  Still, we have kept the following 
+instructions mainly for historic purposes.
+<p>
+It is available at Berkeley's FTP site <tt>mm-ftp.CS.Berkeley.EDU</tt> and called
+<tt>mpeg_encode1.5b</tt>
+<p>
+It has lots of options to tune, so you should spend quite a lot of time
+playing with this. The configuration I use is in file <tt>doc/mpeg.param</tt>.
+<p>
+I've also made some patches that makes possible to use the pattern and motion
+files generated from XaoS. The patch is in <tt>doc/mpeg_encode.patch</tt>. So if
+you want to use these features (they are <emph>EXPERIMENTAL</emph>) you might apply this
+patch and recompile the encoder.
+<p>
+Once you filled the <tt>mpeg.param</tt> file (see comments inside), you should render
+sequence using <tt>mpeg_encode [filename]</tt> and with luck you are done.
+
+<head>Pattern file</head>
+
+Some other files are generated as well. A <emph>pattern file</emph> is generated,
+which contains a <emph>recommended order of P, B and I frames</emph>.
+<p>
+MPEG sequence consist of these three frames. The <emph>I frames</emph> are just images
+saved in a format similar to JPEG files. 
+<p>
+The <emph>P frames</emph> are images which are constructed as a delta from the
+previous one (the latest I or P frame). In case consecutive frames are similar
+(and in animations they often are), a P frame takes much less disk space
+than an I frame.
+<p>
+The <emph>B frames</emph> are constructed from the nearest previous P or I frame
+and the next P or I frame. They take even less disk space, but they are quite
+hard to encode. Also they are <emph>not used as previous frames</emph>,
+so their information is lost once they are displayed. They are usually
+rendered at lower quality than a P or I frame and used just to interpolate
+nearest frame and make animation smoother. It is generally not a good idea
+to make a whole sequence just from B frames.
+<p>
+Using just P frames is generally not a good idea. It makes the file shorter,
+but to jump into Nth frame of animation you need to <emph>recalculate all P and B frames
+since latest I frame</emph>. Decoders often want to jump to some frame (when
+the user asks, or when they can't decode a sequence in time and must skip
+some), so you need to have some I frames in the animation to make this possible.
+The latter reason means that you need to place them quite often. Usually
+they are used for every 15th frame or thereabouts. Because they cost quite a lot,
+in my animations I usually use every 27th frame. To set this distance
+use <tt>-iframedist</tt> option. It should be a multiple of 3.
+<p>
+XaoS generates a recommended order of frames based on its knowledge of
+fractal motion. Situations where the screen doesn't move at all are rendered
+just from P frames (since jumping is usually not required here); in situations
+where the screen changes completely (at least in XaoS's opinion) I frames are used
+and in other cases, a standard sequence <tt>IBBPBBPBBPBBP...</tt> is used.
+<p>
+If your encoder supports this, you should supply this pattern for encoding to
+squeeze out some bytes.
+
+<head>Motion vector files</head>
+
+XaoS also generates a motion vector recommendation for the encoder. This is
+useful for encoding of B and P frames.
+<p>
+If some objects on the screen are moving at a constant speed, motion vectors
+can store that speed, so no image needs to be saved to represent that change.
+<p>
+Calculating this motion vector is a very significant task. If you guess
+them well, you increase quality and reduce file size, which is always great.
+Calculation also takes lots of CPU and it is hard to get optimal vectors (it
+just takes too long).
+<p>
+XaoS knows how the fractals move, so it can calculate this vectors quite
+easily. XaoS saves this information into <tt>*.p</tt> and <tt>*.b</tt> files. (<tt>*.p</tt> are for P
+frames, <tt>*.b</tt> are for B frames). If your encoder supports this, you should
+provide this vector to increase quality. They are <tt>not exact</tt> (XaoS can make
+mistakes); the encoder should try to find its own vectors, then try XaoS's ones,
+and pick whichever is better.
+<p>
+This technique saves quite a lot of bytes in fast zooming/un-zooming
+animations (where images move more than 3 or 5 pixels per frame--since
+most programs look 10-20 pixels around each point for motion vectors).
+<p>
+To enable saving of motion vector files, add the option
+<tt>-rendervectors</tt>.
+
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%controls
+<head>Basic controls</head>
+By default the mouse buttons work in the following way:
+<p>
+<dl>
+<dt>left<dd>zoom in
+<dt>right<dd>zoom out  
+<dt>middle<dd>move fractal in a drag-and-drop fashion
+</dl>
+<p>
+<emph>Note:</emph> Since most Macs only have one button mice, these controls
+are emulated on Mac OS X using modifier keys.  See the help section on 
+<a cocoa>Mac OS X</a> for details.
+<p>
+This behavior can change. If you enable rotation, the first button is used for rotating
+fractals. Also, in fast Julia mode, the first button is used to change the seed.
+<p>
+If you don't have a middle button, press both buttons to enable
+emulation.
+<p>
+After few minutes of zooming you will probably exceed the precision and the
+fractals will get boring. If you are getting strange big rectangles on the screen,
+you probably reached the numeric limit: there is no way to avoid this except
+un-zoom back and choose a different area. It doesn't hurt so much, since you have
+zoomed approximately 64 051 194 700 380 384 times, so there are quite a lot of areas to
+explore. Algorithms with unlimited precision exist, but they are still too
+slow for real-time zooming.
+<p>
+The other possibility is that you have reached the iteration limit. The fractal is
+calculated approximately, and in this case you need to increase number of
+iterations used for approximation (and decrease the speed in the process).
+This is done from the menu or using the arrow keys <emph>Left</emph> and <emph>Right</emph>.
+<p>
+An <emph>Up</emph> and <emph>Down</emph> keys should be used to change zooming
+speed. Note that higher speed costs more and image will be blocky.
+<p>
+This behavior can also change. With palette cycling enabled, <emph>Left</emph>
+and <emph>Right</emph> keys change cycling speed; in continuous
+rotation they change rotation speed.
+<p>
+All other functions are available from the menu, which (in the default
+configuration) are displayed when you move the mouse to the top of the
+screen/window. It is useful to learn the shortcut keys, which are
+shown in gray next to the menu items they trigger.

+%format
+<head>XaoS's file format</head>
+This section describes the format used by XaoS for animations, configuration
+files and saved positions. All these files have a common format, designed
+to be easily readable, to allow manual editing of files and easy conversion by
+other programs.
+<p>
+I also taken care to make it easily extensible for future versions of XaoS
+so I hope there will not be many incompatibilities between various XaoS
+versions.
+<p>
+The format is a simple set of commands executed sequentially. XaoS does not provide
+any variables/cycles as usual scripting languages do, but future extension to
+full-blown Scheme should be easy since the format uses Scheme-like syntax.
+The syntax of every command is:
+<p>
+<tt>(command_name </tt><emph>[param1] [param2]</emph><tt>)</tt>
+<p>
+where parameters are optional and separated by whitespace (an arbitrary number
+of spaces, tabs and newlines). The parameters can have the following types:
+<p>
+<dl>
+<dt>integer
+<dd>number w/o decimal point (<tt>123</tt>)
+<dt>float
+<dd>floating point number in decimal notation with optional exponent (<tt>1.23E2</tt>)
+<dt>keyword
+<dd>text started by quote <tt>'</tt>. It is used to pass various string constants 
+like formula name (<tt>'mandel</tt>) Quote is required for scheme compatibility
+<dt>string
+<dd>Text inside double quotes. The only parameter that should contain whitespace
+<dt>boolean
+<dd><tt>#t</tt> for true or <tt>#f</tt> for false
+</dl>
+<p>
+There is a complete description of all XaoS functions (with some examples) and an
+index of functions in the <a menus>XaoS registry</a>. You may particularly want
+to read about the <a animf>animation functions</a>. Also, the following functions
+are significant:
+
+<dl>
+<dt>load
+<dd>
+This function loads and interprets a file. It works similarly to <tt>#include</tt>
+in C.
+<dt>initstate
+<dd>
+Available in version 3.0 and above, this function resets XaoS's state to default
+values. This command should be at the beginning of each animation file,
+since otherwise some stuff previously enabled by user could cause unexpected
+effects. State is not reset by default before playing animations since it would
+make it impossible to write macros. Current versions don't really need macros, but
+in future versions, when the Scheme programming language will be available, this
+should be a much more interesting subject.
+<dt>usleep
+<dd>
+This function waits for a selected amount of time(in usec) before processing the
+next command. The screen is recalculated and displayed at the beginning of
+the sleep if necessary. The remaining time is spent by waiting, calculating if
+necessary, or performing any animation you entered via animation commands.
+<dt>wait
+<dd>
+Waits until the animation or image rendering is complete. Do not call this
+function when zoom, or continuous rotation is active otherwise deadlock happens. It is
+a good idea to call it immediately before text subtitles are displayed, since it looks
+ugly when they are displayed over a blocky unfinished fractal. Because the
+degree of blockiness at a given instant is a function of your machine speed,
+it may look nice for you but ugly for others with slower machines. Also
+you should call this after an animation is performed, before the switch to another
+fractal happens; since the switch involves calculation, the screen is stopped
+for a while and an unfinished fractal there looks ugly.
+You should also call it, when you want to do something as soon as possible.
+</dl>
+<p>
+Example:
+<p><tt>
+;configure everything for the first frame<br>
+(inistate)<br>
+(palette 1 1163254293 0)	;custom palette<br>
+(cycling #t)			;enable cycling<br>

+				;10 seconds of zooming into selected<br>
+				rectangle<br>
+(usleep 100000000)<br>
+</tt><p>
+The best way to learn XaoS command language is probably to read position files
+and modify them. For example, to create zooming animation from the original
+file:
+<p><tt>
+(initstate)<br>
+(defaultpalette 0)<br>
+(formula 'mandel)<br>
+(view -1.64128273713 -5.50393226816E-05 9.69332308848E-08<br>
+9.69332308834E-08)<br>
+</tt><p>
+Just change the <tt>view</tt> command to <tt>morphview</tt>, and add <tt>usleep</tt>:
+
+<p><tt>
+(initstate)<br>
+(defaultpalette 0)<br>
+(formula 'mandel)<br>
+(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08<br>
+9.69332308834E-08)<br>
+(usleep 10000000)<br>
+</tt><p>
+The following code produces Julia morphing in the real axis:
+<p><tt>

+(fastjulia #t)<br>
+(juliaseed -2 0)<br>
+(morphjulia 2 0)<br>
+(usleep 2000000)<br>

+
+And following is the ``rotozooming'' animation:
+
+<p><tt>

+%cocoa
+
+<head>Mac OS X port</head>
+XaoS has full support for Mac OS X including native menus, dialogs, help,
+Finder integration, drag and drop, and basic AppleScript support. 
+<p>
+The Mac OS X port of XaoS strives to provide a Mac-like experience, while
+retaining compatibility with other platforms.  Some Mac-specific details
+are outlined below.
+
+<head>Zooming</head>
+Since most Macs have one button mice, the middle and right buttons are emulated
+with modifier keys. This means there are multiple ways to perform basic zooming 
+operations:
+
+<dl>
+<dt>Zoom in
+<dd>Hold down the main mouse button.
+<dt>Zoom out
+<dd>1. Hold down the Ctrl key while pressing the main mouse button.<br>
+	2. Use the right mouse button if you have one.<br>
+	3. On laptops with gestures enabled, place two fingers on your trackpad and press the main mouse button.
+<dt>Pan
+<dd>1. Hold down the Shift key while dragging with the main mouse button.<br>
+	2. Drag with the center button if you have one.<br>
+	3. Use the scroll wheel or ball if you have one to pan up/down and left/right.<br>
+	4. On laptops with gestures enabled, swipe two fingers across the trackpad to pan horizontally or vertically.
+</dl>
+
+<head>Keyboard Shortcuts</head>
+XaoS menu functions have been mapped to commonly used Mac keyboard shortcuts.  For example,
+Open is Cmd-O and Undo is Cmd-Z, just as you would expect.
+
+<p>However, XaoS also has its own 
+long-standing tradition of cross-platform keyboard shortcuts.  These keyboard shortcuts are 
+also displayed in the menus inside parentheses.  For example, the menu item "Autopilot (a)" 
+means that you can press a (with no modifier keys) to activate Autopilot.  All of these 
+traditional XaoS shortcuts do not use modifier keys, so they do not conflict with any standard 
+Mac OS X shortcuts.
+
+<p>In some cases, the same function may be performed with both a traditional
+XaoS shortcut and a Mac OS X-specific shortcut.  You can choose whichever one is more 
+comfortable for you.
+
+<head>Full Screen Mode</head>
+The Mac OS X port supports a full screen mode.  To enter it, select <emph>Mac OS X Full Screen Driver</emph>
+from the <emph>UI -> Driver</emph> submenu.  Once you enter full screen mode, the menu bar will
+automatically hide.  To access the menu bar, move your mouse to the top of the screen and the menu
+bar will slide into view.  When you move your mouse away, it will automatically disappear again.
+To return to windowed mode, select <emph>Mac OS X Windowed Driver</emph>
+from the <emph>UI -> Driver</emph> submenu.
+
+<head>Videator Support</head>
+XaoS for Mac OS X can send a live video stream to Stone Design's Videator (<tt>http://stone.com/Videator/</tt>),
+which can then do post-processing using Mac OS X's core video technology. This combination creates mind-blowing visuals
+that are great for VJing (live video performance art).
+<p>To turn on output to Videator, select <emph>Videator Output</emph> from the <emph>UI</emph> menu.
+See <tt>http://stone.com/Videator/VJ.html</tt> for more details on how using Videator with XaoS.

+%aa
+
+<head>AA-lib driver</head>
+
+The AA driver is currently the most advanced and portable driver for XaoS.
+It is based on AAlib--a high quality ASCII-art library developed by the AA-project.
+(see <tt>http://aa-project.sf.net</tt>)
+<p>
+It is a fully featured XaoS driver for text mode displays. It supports 256 colors
+and the mouse where possible.
+<p>
+It also has some extended features available from the UI menu:
+<p>
+<dl>
+<dt>Attributes
+<dd>AA-lib may use character attributes to improve image quality.
+  By default it uses normal, dim and bold characters where possible,
+  but you can also enable different attributes like reversed or bold font 
+  characters. You may also enable usage of non ansii/reversed characters if
+  your device supports it.
+<dt>Font
+<dd>AA-lib uses a bitmap image of the font to prepare the approximation table
+used for ASCII art rendering. This bitmap is expected to be same as the one used
+by your device. AAlib performs detection where possible however some devices
+(like UNIX text terminals or MDA) do not support this. AAlib has few font
+images compiled in, so in this case you should try to use one of them to
+achieve best results.
+<dt>Inversion
+<dd>Some devices use inverse video: use this to get correct results on such devices.
+<dt>Dithering mode
+<dd>Dithering is an way to get more exact color in approximations, by combining 
+  more characters; but this method can produce ugly looking noise on certain images.
+  Use this menu to disable or tune it.
+<dt>Palette options
+<dd>By default AA driver uses the XaoS palette to render images, but it quite often
+looks ugly on text displays. Here you can choose a special text palette instead. Note that with 
+filters enabled, the results may be rather ugly. This function is available from
+the <emph>palette menu</emph>.
+<dt>Save text screen
+<dd>The normal save function will generate a PNG image instead of nice
+  ASCII-art. To save ASCII art use this function instead. It supports many  
+  text file formats like HTML, ANSI, more, etc... It will also ask you for
+font and attributes(see above). It is available from the <emph>file
+menu</emph>.
+</dl>
+<p>
+The AA-lib driver also provides the full set of standard AA-lib's command line
+options. You may use them to tune parameters like gamma correction, and so on.
+See <tt>xaos -help</tt> or the AA-lib documentation for details.
+<p>
+The AA driver was written by Jan Hubicka, 1997.

+%dos
+
+<head>DOS driver</head>
+This is a fully featured driver for DJGPP and allegro. 
+It supports many VGA modes, VESA 1.0--3.0, VBE/AF, S3 and some other cards.
+<p>
+The following problems may occur:
+<p>
+<dl>
+<dt>Some DPMI servers may cause problems
+<dd>Some DPMI servers like the one from Novell/Dr/Open DOS are buggy. Use clean DOS
+  instead and XaoS will automatically start <tt>cwsdpmi</tt>.
+  Under Open Dr DOS use <tt>dpmi off</tt> at command line to disable it.
+<dt>Higher resolutions don't work
+ <dd>If your videocard has enough memory for the selected resolution,
+ you most probably have an unsupported videocard.
+ Please use a VESA BIOS extension on this videocard. (See the note about VESA
+ at the end of this section.)
+<dt>XaoS needs a coprocessor
+ <dd>I don't distribute a coprocessor library linked into XaoS because it is too slow for
+ a real-time zoomer. Coprocessor emulation will not help, because xaos works in protected mode.
+<dt>XaoS needs mouse driver to be usable
+<dt>XaoS works slowly in higher resolution
+ <dd>This could also be caused by Allegro's slow driver or your videocard's VESA BIOS.
+ You could try some other VESA BIOS extension instead.

+VESA support in the BIOS so you don't need any additional software, while others
+need support from a special program. Also some VESA BIOS implementations are
+buggy or suboptimal; there are 3 different versions, version 1.0 is many times
+slower than 2.0, which has support for protected mode and linear framebuffers.
+So if you have problems with higher resolutions, or some graphics modes are
+not available (like 320x200 truecolor), you might try some software package
+which emulates VESA.
+<p>
+The most famous VESA emulating program is Scitech Display Doctor. It has support
+for many videocards and is quite reliable. It's disadvantage is that it is
+shareware and works for only 30 days. You might also look on
+<tt>ftp.simtel.net</tt>, where there are many VESA emulation packages such as
+<tt>s3vbe</tt> or the new FreeBe project at
+<tt>http://www.talula.demon.co.uk</tt>

+%ggi
+
+<head>GGI driver</head>
+
+GGI stands for General Graphics Interface. Part of this project is to develop
+libggi, a portable graphics library, and XaoS's GGI driver uses that.
+It is experimental, since the API of libggi is not stabilized yet.
+There are some problems with keyboard handling--the shift key doesn't work
+yet.
+<p>
+Everything else might work well, but there are no guarantees. It is alpha quality
+software.

+%plan9
+
+<head>Plan9 driver</head>
+
+Plan9 is a very nice small operating system by the authors of Unix at Bell Labs.
+It is very incompatible with other operating systems; even the C compiler and
+header files are different, but XaoS should work well there (even on the
+limited free demo installation without any POSIX compatibility stuff)
+<p>
+There are a few limitations: the file selector and image saving don't work.
+You can save position files and then later render them on the other OS, or save
+screenshots.
+<p>
+Plan9 terminals also don't provide any way to catch the arrow keys, so you
+can't use them. Use the mouse to navigate in the menus. Also, getting the screen
+resolution is impossible, so use <tt>-pixelwidth</tt> and <tt>-pixelheight</tt>
+instead of <tt>-screenwidth</tt> and <tt>-screenheight</tt>.
+<p>
+By default XaoS changes the colormap. This will collide with other colorful
+programs like Mortha. You can disable this behavior using
+<tt>-nopalette</tt> switch, but this will slow down XaoS.

+%SVGAlib
+
+<head>SVGAlib driver</head>
+
+This is a driver for Linux SVGAlib. I really like this driver, because
+I much prefer full screen zooming instead of a small 320x320 window in X11.
+It was one of the first drivers for XaoS and is fully featured. 
+The following problems can occur:
+<p>
+<dl>
+<dt>XaoS doesn't initialize graphics mode
+<dd>when started under users other than root SVGAlib requires root privileges
+  to directly access the hardware. When you really want to start XaoS as a
+  normal user, enable the suid bit (<tt>chmod +s</tt>) at XaoS executable.
+  note that I take care to disable all security holes caused by this
+  bit so I believe it is safe.
+<dt>Mouse doesn't work
+<dt>Screen is blank at higher resolutions
+<dd>Both this problems are probably caused by misconfiguration of 
+SVGAlib. Please configure it in <tt>etc/vga/libvga.cong</tt> or 
+<tt>/usr/local/lib/libvga.conf</tt>
+GPM can also cause problems. Try to kill it before starting XaoS.
+<dt>When I switch console I can't switch back
+<dd>This is another typical SVGAlib bug. Try to hold <tt>F</tt> key longer than <tt>alt</tt>.
+  It helps on my computer. On older SVGAlib there was a famous ``enter bug'' that caused
+  a crash after pressing enter. Try to update to a newer release.

+%win32
+
+<head>Win32 driver</head>
+
+This is a driver for Windows 9x and NT. It is new since version 3.1 and
+because of some oddities of Windows API it may be rather unstable.
+Please report all bugs. In case of problems you could use the DOS version
+of XaoS instead.
+<p>
+The driver should work in all bit depths, but 16 color mode is not natively
+supported by the XaoS engine. XaoS internally works in 32k colors and
+the result is converted to 16 colors by Windows. Because Windows
+conversion routines are slow and ugly, the result is slow and ugly.
+Please configure your display to another bit depth to ``solve''
+this problem.
+<p>
+Use <tt>-size WIDTHxHEIGHT</tt> command line option to change the default
+window size.
+<p>
+This driver also maps to native Windows look and feel. There is a small
+problem with combo boxes in dialogs. They are expected to give you a choice
+between a few strings. The keyboard controls (changing choice by arrow keys)
+work, but mouse selection is broken. If you know how to solve this bug,
+please let me know.
+<p>
+XaoS is a UNIX application and has many command line options. 
+Some features are not available from the GUI.
+Because Windows applications can't have normal output,
+most of the critical messages are displayed in message boxes, but
+some longer messages are omitted. The most significant omission is the help
+about command line options that you can find in <tt>doc/cmdopts.txt</tt>.
+<p>
+One thing that might be confusing is that animation rendering mode doesn't
+display anything, but only renders images. Start the rendering,
+and a message box will inform you that XaoS is entering the calculation
+loop. Relax and wait for the message box signaling the end of the loop.
+<p>
+Note that XaoS also supports the <a dX-window>DirectX</a> API.

+it may be rather unstable.  Please report all bugs. In case
+of problems you could use the DOS version of XaoS instead.
+<p>
+The DirectX driver is an alternative to the windowed <a win32>win32 driver</a>.
+If you have DirectX installed, this driver is used by default. It has
+almost the same behaviour as the <a win32>win32 driver</a> so please read its
+documentation for more details. The only difference should be the display
+speed.
+<p>
+The driver supports only hicolor and truecolor modes. There is no support
+for 256 and 16 color modes because of palette collision problems. The win32
+driver will be used in these cases by default, so this should cause no
+problems.
+<p>
+If you are experiencing problems with this driver, you might want to

+<p>
+This driver allows the Windows port of XaoS to run in full screen mode.
+The driver supports 256, 65536 and 16777216 color modes (24bpp and 32bpp)
+in all resolutions supported by DirectX.
+You can change graphics mode by pressing the <tt>=</tt> key
+(or by using the UI/Resize menu). If the selected mode is not supported,

+%BeOS DirectWindow WindowScreen
+
+<head>BeOS support</head>
+
+XaoS has pretty advanced support for BeOS R4. It works on both PowerPC and
+Intel platforms, supports multithreading, the clipboard, file dragging,
+has native look and feel and can work as an image translator from XaoS files
+to images.
+<p>
+The first version of the BeOS driver was written by Jens Kilian and later
+extended by Jan Hubicka.
+<p>
+<head>Installation</head>
+<p>
+You can start the installation script to do everything for you. If you want
+something special, read this section.
+<p>
+In order for XaoS to work you need to keep the executable together with
+its data files (<tt>help</tt>, <tt>examples</tt>, <tt>catalogs</tt> and the <tt>tutorials</tt> directory)
+<p>
+When first started, XaoS registers two new mime types called
+<tt>image/x-xaos-position</tt> for XaoS Position Files and
+<tt>video/x-xaos-animation</tt> for XaoS Animation Files,
+registers icons for them and sets itself as default application.
+<p>
+<head>Available display drivers</head>
+<p>
+XaoS supports following drivers:
+<p>
+<dl>
+<dt>BeOS
+<dd>Standard windowed driver using application server
+<dt>DirectWindow
+<dd>Driver done using Game Kit's direct window class
+<dt>WindowScreen
+<dd>Fullscreen driver.
+</dl>
+<p>
+By default, XaoS starts in windowed mode and uses the application server for output.
+You could change the driver to DirectWindow to use direct access to video RAM.
+Note that this mode is slower in most cases, and not supported by some videocards.
+<p>
+The BeOS driver by default chooses the most similar bitmap supported by XaoS
+to achieve best and fastest results.
+In the UI menu you can change this default choice to another one if you wish.
+Also you can ask the BeOS and DirectWindow to resize to fullscreen mode.
+<p>
+XaoS also supports real fullscreen mode using the BWindowScreen API. To switch
+XaoS to this driver, use the UI menu. If you want to use this mode by default,
+use the <tt>-driver WindowScreen</tt> command line option.
+<p>
+This driver differs a lot from windowed ones. It use direct access to the video
+card, allowing you to change video mode. Also, the 256 color mode
+can access the palette, so it is not dithered like the windowed mode.
+Because BeOS can't do GUI in fullscreen mode, XaoS uses its own toolkit.
+I hope you will feel confortable in it.
+<p>
+<head>XaoS as translator</head>
+<p>
+You should be able to open XaoS files in graphics applications
+such as ShowImage or ArtPaing. In Preferences you can find the DataTranslations
+program, that can be used to set the size, type and DPI of the resulting image.
+Also antialiasing can be enabled.
+<p>
+Note that <emph>translation can take a while</emph>. So be patient and
+wait for the result.
+<p>
+If the translator doesn't work, ensure that you have a link to the XaoS executable
+in <tt>/boot/beos/system/add-ons/Translators/</tt>.

+%X11
+
+<head>X11 driver</head>
+This was the first driver done for XaoS. It supports many visuals, shared
+colormaps and MitSHM extension.
+<p>
+Bugs/limitations:
+<p>
+<dl>
+<dt>XaoS makes some X servers too busy
+<dd>Sometimes XaoS generates images faster than X can display them.
+In this case XaoS responds poorly to the mouse, and other applications slow
+down too. This happens especially often on old R4 servers. Use <tt>-sync</tt>
+to avoid this problem. Note that <tt>-sync</tt> does <tt>not</tt> make all
+communication with X asynchronous; it just adds one additional XSync call.
+So the slowdown is not as large as you might expect.
+<dt>Does not work on all visuals
+<dd>This driver supports only 8bpp pseudocolor/grayscales, 15,16,24 and 32bpp truecolor, 1bpp and 8bpp staticolor visuals.
+<dt>Palette rotating does not work for 8bpp pseudocolor w/o private palette

+%tutorial
+
+<head>XaoS tutorial</head>
+
+This is a brief introduction to the basic XaoS features.
+
+<head>How to zoom</head>
+ The main advantage of XaoS is that after a few seconds' delay to calculate
+ the first image, you may choose any point with the mouse and press the <emph>left</emph> button.
+ The image will start to zoom smoothly into the point you choose. You may move
+ the mouse and zoom smoothly into interesting areas. By pressing the <emph>middle
+ button</emph> (or <emph>left+right</emph> buttons) you may also
+ <emph>move the image</emph> using ``drag & drop'' if you missed an interesting
+ place. <emph>Unzooming</emph> is also possible by using the <emph>right button</emph>,
+ but it is much slower because optimizations are not so effective as for zooming.
+<p>
+ In case you think that the default <emph>speed</emph> is boring (it is quite slow, to
+ make XaoS smooth on a slow computer) you may change it by pressing <emph>arrow
+ up/down</emph>. But faster zooming is more expensive, so if the speed is too high
+ you will see little but funny colorful blinking rectangles.
+ 
+<head>Autopilot</head>
+
+ To make XaoS yet more impressive we made a special autopilot that
+ automatically drives into interesting boundaries of the set. So you can
+ press <tt>A</tt>, play your favorite music, drink coffee and relax. I never
+ tried this but it should be really relaxing! Many pictures in the XaoS
+ gallery were discovered using the autopilot.
+<p>
+ The autopilot also has some additional features. It turns back when the
+ zoomed picture stops being interesting, and is able to spot when it's zoomed
+ into a really boring part (or has reached the limit of floating point
+ numbers) and restart zooming from the top.
+<p>
+<head>Various fractal formulae</head>
+
+ XaoS also supports formulae other than the Mandelbrot set. You may change
+ <emph>formula</emph> using the <emph>number keys</emph> 
+ or <emph>SHIFT+letters</emph>.
+
+
+<p>
+ On keys <tt>1</tt> to <tt>5</tt> are <emph>Mandelbrot sets of various power</emph>. The ``normal''
+ Mandelbrot set is on key <tt>1</tt>. 
+<p>
+ On key <tt>6</tt> is a fractal called <emph>Newton</emph>. It is Newton's famous formula for finding roots.
+<p> 
+ On key <tt>7</tt> is the <emph>fourth ordered Newton</emph> fractal.
+<p>
+ On key <tt>8</tt> is a fractal called <emph>Barnsley</emph>.
+<p>
+ On key <tt>9</tt> is <emph>Barnsley's second</emph> fractal.
+<p>
+ On key <tt>0</tt> is <emph>Barnsley's third</emph> fractal.
+<p>
+ With keys <tt>SHIFT-A</tt> you can display a fractal called <emph>octo</emph>. It is a fractal that Thomas
+ discovered in fractint.
+<p>
+ With keys <tt>SHIFT-B</tt> you can display a fractal called <emph>Phoenix</emph>. It is a very nice and quite famous fractal.
+<p>
+ With keys <tt>SHIFT-C</tt> you can display a fractal called <emph>Magnet</emph>. This fractal has quite a complex formula so it is
+ a bit slow. 
+<p>
+ With keys <tt>SHIFT-D</tt> you can display the <emph>Magnet2</emph> fractal.
+<p>
+ The rest of the built-in fractals are accessible through an other menu, but 
+ you can still use the hotkeys.
+<p>
+ On <tt>SHIFT-E</tt> is a fractal called <emph>Triceratops</emph> found by Arpad.
+<p>
+ On <tt>SHIFT-F</tt> is a fractal called <emph>Catseye</emph> found by Arpad.
+ This is more interesting if you change the bailout value.
+<p>
+ On <tt>SHIFT-G</tt> is a fractal called <emph>Mandelbar</emph>. It was in
+ Gnofract4d, and they found it at:
+ http://mathworld.wolfram.com/MandelbarSet.html
+<p>
+ On <tt>SHIFT-H</tt> is the <emph>Lambda</emph> fractal.
+<p>
+ On <tt>SHIFT-I</tt> and <tt>SHIFT-J</tt> are the <emph>Manowar</emph> 
+ and <emph>Spider</emph> fractals, they were found by users of fractint. 
+ (Scott Taylor or Lee Skinner)
+ It was on http://spanky.triumf.ca/www/fractint/
+ taylor_skinner_type.html
+<p>
+ The next 3 fractals are famous classic fractals.
+<p>
+ On <tt>SHIFT-K</tt> is the <emph>Sierpinski</emph> Gasket.
+ You can change its shape by selecting another Julia seed. 
+ (This is for technical reasons.)
+<p>
+ On <tt>SHIFT-L</tt> is the <emph>Sierpinski Carpet.</emph>
+ It's shape can also be changed by selecting another Julia seed.
+<p>
+ On <tt>SHIFT-M</tt> is the <emph>Koch Snowflake.</emph>
+<p>
+ 
+
+<head>Out-coloring modes</head>
+
+ To make fractals yet more interesting, more coloring modes for points
+ outside the set are provided. ``Classical coloring mode'' uses the number of
+ iterations that the orbit required to escape to (nearly) infinity. You can change this
+ mode from the <emph>Fractal menu</emph> or by pressing key <tt>C</tt>
+ To see more about coloring modes, try the tutorial on <tutor incolor.xaf>Incoloring modes</tutor> from the XaoS features overview.
+<p>
+ Those cryptic names for coloring modes are mathematical formulae, where <emph>iter</emph> means number
+ of iterations, <emph>real</emph> means real coordinate of last orbit, and <emph>imag</emph> means imaginary
+ coordinate of last orbit.
+<p>
+<head>In-coloring mode</head>
+
+ In-coloring mode is similar to out-coloring, except that it changes how
+ things inside the set are displayed. This can also be changed from the <emph>fractal
+ menu</emph> or by pressing <tt>F</tt>. 
+ <p>
+ You might also want to see the tutorial on
+ <tutor outcolor.xaf>Out-coloring modes</tutor> from the XaoS features overview.
+
+<head>Planes</head>
+
+ All fractals displayed by XaoS are functions with a complex parameter. It
+ can be displayed in the normal complex plane, where x is the real part of
+ the number, and y is the imaginary part; but it can also be displayed in
+ a number of other planes. You can select the plane to use from the
+ <emph>Fractal menu</emph>, or by pressing <tt>I</tt>.
+<p>
+ Like the coloring modes, planes have cryptic names. You guessed it, they're
+ mathematical formulae. Here <tt>mu</tt> means coordinates in the normal
+ complex plane. If you have coordinates in <tt>1/mu</tt> plane, and you need
+ coordinates in the a complex plane (to calculate the Mandelbrot set) you
+ simply use the coordinates as mu. Lambda is another plane that can be
+ converted to mu using a similar formula.
+ <p>
+<dl>
+ <dt>mu
+	<dd>normal mode.
+
+ <dt>1/mu
+	<dd>Inversion: infinity goes to 0 and 0 goes to infinity.
+
+ <dt>1/(mu+0.25)
+	<dd>Similar to inversion, but moves the center outside of the
+        Mandelbrot set so that it looks parabolic.
+
+ <dt>lambda
+	<dd>Lambda plane.
+
+ <dt>1/lambda
+	<dd>Inversion of lambda plane.
+
+ <dt>1/lambda-1
+	<dd>Inversion with moved center.
+
+ <dt>1/(mu-1.40115)
+	<dd>A very interesting mode for the Mandelbrot set. It makes small things
+	big, so you can browse the set's details easily.
+</dl>
+<p>
+ 
+<head>Mandelbrot/Julia switching</head>
+
+ Most of the fractals displayed by XaoS (currently all of them) have two
+ forms: Mandelbrot and Julia. Every point in a Mandelbrot set has its
+ own Julia set. To see more about this correspondence, try the tutorial on
+ <tutor julia.xaf>Julia set</tutor> from the Introduction to fractals.
+<p>
+ In the Mandelbrot mode, you can get a corresponding Julia by moving the mouse
+ to an interesting point and pressing <tt>M</tt>. To get back press <tt>M</tt>
+ again. Some fractals (Barnsley and phoenix) are already in their Julia
+ versions, because the Mandelbrot ones are boring. But by pressing <tt>M</tt>
+ in such fractal you should get the Mandelbrot version, and by choosing another
+ point as the base point and pressing <tt>M</tt> again you should get a
+ completely different fractal. The most interesting points for Julia sets
+ are at the boundaries of the Mandelbrot set. Most of the Julias inside or
+ outside the set are boring.
+<p>
+ 
+<head>Fast Julia preview mode</head>
+
+ Fast Julia mode is a quick way to find a point to use as a base for the Julia
+ set.. Just press <tt>J</tt> and a small Julia set will be displayed in the top
+ left corner. Then move the mouse around with button 1 depressed, and the Julia
+ for the point the mouse is over will be automatically generated. 
+ 
+<head>Palette</head>
+
+ If you think that the default XaoS colors are ugly or you are just
+ bored by them you can change it by pressing <tt>P</tt>. XaoS will
+ automatically generate random palettes. Many of them look ugly, so
+ press <tt>P</tt> again to get another one until you find one you like.
+<p>
+<head>Filters</head>
+
+ Many interesting effects are done by post-calculation <a filter>filters</a>.
+ XaoS has filters that do everything from embossing, through motion-blurring,
+ right through to turning the fractal into a stereogram. To enable them use
+ the <tt>filter menu</tt> or press <tt>E</tt>.
+<p>
+<head>Palette cycling</head>
+
+ This is a very old trick that makes the Mandelbrot set a little flashier. You
+ may enable or disable it using <tt>Y</tt>. In the truecolor modes you need
+ to enable the <a palettef>palette emulator filter</a> first. This is done
+ via the <tt>E</tt> key, or from the filter menu.
+<p>
+<head>Changing number of iterations</head>
+
+ To calculate fractals perfectly, you need an infinite number of
+ iterations. XaoS does just the first few of them, so after lots of zooming
+ you may get into a place that looks quite boring, and the boundaries of the
+ set are rounded, without any interesting details. This can be changed by
+ changing the number of iterations:
+ <p>
+ Press and hold <tt>arrow right</tt> and wait until iterations are high enough.
+ This may slow down calculation much. To reduce number of iterations
+ press <tt>arrow left</tt>.
+ 
+<head>Changing resolution</head>
+
+ XaoS usually starts in a low resolution (320x200 or thereabouts) to make
+ calculations faster. If you have a fast computer or you need to
+ save bigger <tt>.gif</tt> images, you may change the resolution. This
+ can be done by pressing <tt>=</tt> in the full screen drivers, or simply
+ by resizing the XaoS window.
+
+<head>Changing driver</head>
+
+ XaoS usually has more than one driver available. You may change it on
+ the fly in case you want a different one. For example, XaoS started in X11
+ can be switched at runtime to use the AA driver. This can be done from the
+ UI menu.
+ <p>
+ This action is bit dangerous, because XaoS can crash during initialization
+ if there is some problem with initialization; XaoS tries to initialize a new
+ driver, and if it fails it attempts to return back to the original. Sometimes
+ this is impossible, and all XaoS can do is terminate..
+
+<head>Other features</head>
+XaoS has many other features, but they don't fit into this tutorial. Most of
+them are available from the menu, so you can experiment with them. You might
+also want to see the <emph>animated tutorials</emph> from the <emph>help menu</emph>,
+to have an idea what XaoS can do.

+XaoS has support for drawing lines. These functions are available only in
+animations and could be used to show some parts of fractals or draw simple
+diagrams. See the tutorial ``<tutor intro.xaf>Introduction to fractals</tutor>''
+for examples of this feature.
+<p>
+Lines can be drawn in <emph>screen</emph> coordinates, where 0,0
+is the top left corner and 1,1 is bottom right, <emph>scaled</emph>
+coordinates, which are similar, but scaled to keep 0,0--1,1 rectangular,
+or <emph>Fractal</emph> coordinates, to draw a line at an exact position
+on the screen.
+<p>
+The color of the line should be specified by the <a color><tt>color</tt></a> command.
+You might draw an arbitrary number of lines and, later, morph them. Each line is
+identified by a unique numeric key; the current key can be set using <tt>linekey</tt>.
+Commands for changing lines operate on the line with the current key.
+(Lines drawn in sequence have consecutive numbers.)
+<p>
+For example:
+<p><tt>
+(color 'red)<br>
+(line 'scaled 0.3 0.5 0.7 0.5)<br>
+(line 'scaled 0.3 0.5 0.7 0.5)<br>

+%periodicity
+<head>Periodicity checking</head>
+<p><emph>Syntax</emph>:(periodicity bool)
+<p>
+Periodicity checking is one way to speed up the calculation. Areas inside the
+set always need <a maxiter><tt>maxiter</tt></a> iterations to determine that
+the point is probably inside the set (while it is rare for areas outside to
+need anywhere near that much). Often the orbital trajectory falls into a
+periodic, repeating cycle; if that can be detected, the calculation can be
+stopped early, as there's no way that the orbit can ever leave the cycle
+again (hence it cannot diverge, hence the point must be inside the set).
+<p>
+Implementating this method efficiently is quite problematic. It slows down
+the cases where cycles are not found, because cycle-checking is quite hard work
+and has to take place for all points, even those that don't become cyclic.
+Because of the inexactness of floating-point calculations, the cycles are
+never exact, so you need to use an error value. Higher error values mean that
+cycles will be detected sooner, while lower error values increase the
+exactness of the calculation. Higher values can introduce serious errors,
+especially at the front of the Mandelbrot set. XaoS detects this automatically
+and corrects for it in most cases, but sometimes it might be wrong. Also,
+other optimizations in XaoS (such as boundary tracing) don't give this method
+much of a chance to run, since areas inside the set are usually not
+calculated at all.
+<p>
+That's why the advantages of this optimization are questionable. You should
+probably experiment with enabling and disabling it. Sometimes XaoS is faster
+with this enabled, sometimes when disabled. Also, this method works only
+when <a incoloring>incoloring</a> methods are disabled, and only for some
+fractal types (some fractal types, e.g. newton, don't have any concept of
+an area `inside the set' at all.)

+When the fractal set is calculated, a orbital trajectory is examined for each
+point. If the orbit diverges to infinity, the point is outside the set.
+Otherwise, the point is inside the set. For exact calculations, you need to
+know the entire orbital trajectory, which is infinitely long for areas inside
+the set, so fractals cannot be calculated exactly. By default, XaoS calculates
+at most 170 positions (iterations) and then gives up; if the point is still
+inside the bail-out value, it guesses that the point is inside the set.
+<p>
+When zoomed into a detailed area, especially one close to the set boundary,
+this value could become too low, and the fractal will become boring.
+You might try increasing this value if you want to get the image interesting

+%stereogram
+<head>Random dot stereogram</head>
+<p>
+   Fractal images are good as a base for random dot stereograms. In
+   case you don't know what these are, please point your browser to
+   Google or another search engine and find some articles about such
+   images, because learning to read such images takes some effort. They
+   make it possible to generate three dimensional images on a normal monitor
+   without any additional hardware, by exploiting bugs in the human brain
+   (although you need two working eyes, and some people never learn to
+   see them; they can simply ignore this feature).
+<p>
+   XaoS is able to generate these images in animations, so you may use
+   all normal XaoS functions (except palette changing and palette rotation,
+   which makes no sense applied to a stereogram). To make the animation yet
+   more exciting, XaoS emulates ``falling'' into the set; while you zoom in,
+   your distance from the set drops and drops--but you never hit it; when the
+   set reaches the level of your monitor, the distance is changed again so
+   you are far away.
+<p>
+   To make this work right, XaoS needs to know the <emph>exact size of your
+   monitor</emph>. Because most platforms have no way to determine this, you need to
+   use <emph>command line options</emph> to tune it. If it's not set or is wrong,
+   the stereograms will probably be impossible to see (if your monitor is too
+   big or resolution too low), or the images will seem to be shallow (if your
+   monitor is too small or resolution too high).
+<p>
+   By default XaoS expects my 15" monitor (29.0cm x 21.5 cm). Another
+   cause of problems is the virtual screen supported by some windowed
+   environments (like some X servers) that makes a program think that the
+   resolution is higher than it actually is, and you see only part of
+   this extra-large screen.
+<p>
+   The worst thing you could possibly do is to run full-screen XaoS in some
+   graphical windowing system (OS/2 on top of Windows or Wine on top of Linux,
+   perhaps) where XaoS can't tell the real size of its window at all. In such
+   cases, it's normally better (not to mention faster) to run XaoS natively,
+   rather than under such an emulation layer.
+<p>
+   The following command line options are provided to specify sizes:
+<p>
+<dl>
+<dt><tt>-screenwidth</tt>, <tt>-screenheight</tt>
+          <dd>Lets you specify the size of your screen in centimeters. Note that
+          you need to specify the size of the visible image on the monitor, not
+          the size with edge borders, or the size of the tube. The simplistic
+          `my monitor is 17", just turn 17" into centimeters' doesn't work;
+          that 17" is a marketing figure and has only a vague connection to
+          reality. Get out a ruler and measure it.
+
+   <dt><tt>-pixelwidth</tt>, <tt>-pixelheight</tt>
+          <dd>Lets you specify the exact size of a single pixel, if XaoS cannot
+          determine this for itself from your screen size.
+</dl>
+<p>
+   These options are used by some other parts of XaoS as well, so you should
+   use them even when you don't want to see stereograms. You should probably
+   write a small starting script (or alias, or shortcut; whatever your environment
+   uses) that passes the correct parameters to XaoS.
+<p>
+   If the window is <emph>smaller than 8cm in any direction</emph>, you will probably be
+   unable to see anything; make the window bigger.
+
+   The correct way to see XaoS stereograms is:
+<dl>
+    <dt>1
+    <dd>Start XaoS with options specifying the exact size of your screen or one pixel on it
+     <dt>2
+     <dd>Sit 60cm away from monitor
+     <dt>3
+     <dd>If you use a windowed environment, resize XaoS's window to make it wider than, say, 15 cm.
+     <dt>4
+     <dd>Enable the filter (by pressing <tt>E</tt>)
+     <dt>5
+     <dd>focus on a point far away from the monitor (try to use your
+       own reflection, if your monitor's not antireflective); the random blurring should
+       eventually fall into the pattern of a Mandelbrot set.
+     <dt>6
+     <dd>Carefully use your mouse to zoom into interesting areas
+     (it is easy to lose concentration when you are not trained; but you can use
+     the autopilot...)
+     <dt>7
+     <dd>Enjoy animation :)
+</dl>
+<p>
+   If you still can't see the stereograms, it could be that the fractal, or your eye,
+   is deformed. A deformed fractal can be caused by your specifying your monitor size
+   wrongly. Visual problems that damage depth perception, as well as problems like
+   astigmatism, can make it impossible to see stereograms at all.

+<center>Version 2, June 1991<p>
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.<br>
+                          675 Mass Ave, Cambridge, MA 02139, USA<br>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+</center>
+<head>Preamble</head>
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+<p>
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+<p>
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+<p>
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+<p>
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+<p>
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+<p>
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+<p>
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+<head>GNU GENERAL PUBLIC LICENSE<p>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</head>
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+<p>
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+<p>
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+<p>
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+<p>
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+<dl>
+<dt>
+<dd>
+<p>
+a)
+    You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+<p>
+b)
+    You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+<p>
+c)
+ If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+</dl>
+<p>
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+<p>
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+<p>
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+<p>
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+<dl>
+<dt>
+<dd>
+<p>
+a)
+    Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+<p>
+b)
+    Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+<p>
+b)
+    Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+<p>
+</dl>
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+<p>
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+<p>
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+<p>
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+<p>
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+<p>
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+<p>
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+<p>
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+<p>
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+<p>
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+<p>
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+<p>
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+<p>
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+<head>NO WARRANTY</head>
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+<p>
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+<p>
+<center>END OF TERMS AND CONDITIONS</center>
+<head>How to Apply These Terms to Your New Programs</head>
+<p>
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+<p>
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+<p>
+<emph>
+<tt>
+    (one line to give the program's name and a brief idea of what it
+    does.)<br>
+    Copyright (C) 19yy  (name of author)
+<p>
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+<p>
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+<p>
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+</tt>
+</emph>
+<p>
+Also add information on how to contact you by electronic and paper mail.
+<p>
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+<p>
+<emph>
+<tt>
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+</tt>
+</emph>
+<p>
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+<p>
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+<p>
+<emph>
+<tt>
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+<p>
+  (signature of Ty Coon), 1 April 1989
+  Ty Coon, President of Vice
+</tt>
+</emph>
+<p>
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+xhtml2rest - Convert xhtml to reStructuredText
+
+SYNOPSIS
+========
+
+xhtml2rest *xhtmlfile* > *restfile*
+
+DESCRIPTION
+===========
+
+``xhtml2rest``, which, far from being a decent and complete program, is
+only something to begin with, hopefully processes the given UTF-8
+xhtml file and produces reStructuredText "source code" in the standard
+output.  If your input is html and/or not in UTF-8, you can convert it
+to UTF-8 xhtml using ``iconv`` and ``tidy``:
+
+    iconv -f *source_encoding* -t utf-8 *source_html* > *html_utf8*
+
+    tidy -utf8 -asxml -o *xhtmlfile* *html_utf8*
+
+    xhtml2rest *xhtmlfile* > *restfile*
+
+Interestingly, since reStructuredText is not simple markup, but has
+very strict rules with the intention that the source is perfectly
+readable, it turns out that converting html to reStructuredText is
+actually *rendering*. ``xhtml2rest`` is a small rendering engine. Since
+I had no time to study how existing rendering engines work, I had to
+reinvent the wheel. So although the code is clean (I actually wrote it
+twice), I doubt that the core logic is adequate for future extensions.
+But it's better than nothing. There is some documentation in the code,
+but feel free to email me if you need more explanations.
+
+LIMITATIONS
+===========
+
+I created ``xhtml2rest`` for a very specific job. It does that job
+correctly, but for your web page it might not work. It should not be
+very hard, however, either to improve the code, or to determine what
+it is in your web page that confuses ``xhtml2rest`` and remove it.
+
+Other than that, there are the following limitations:
+
+* No indented tables
+
+* No multi-col or -row spans in tables
+
+* No support for \<br>
+
+* Not tested in nested tables (check http://www.w3m.org/story.html)
+
+* \<th> support is quick and dirty
+
+* If the same anchor text is met twice, the anchor is ignored
+
+* No indented \<pre> elements (but I'm not sure the HTML standard
+  allows them)
+
+* Images are ignored
+
+* The word HARDWIRED in the code indicates a hardwired hack which is
+  specific to the job I wanted ``xhtml2rest`` to do.
+
+META

+# SYNOPSIS
+#
+#   AX_CC_MAXOPT
+#
+# DESCRIPTION
+#
+#   Try to turn on "good" C optimization flags for various compilers and
+#   architectures, for some definition of "good". (In our case, good for
+#   FFTW and hopefully for other scientific codes. Modify as needed.)
+#
+#   The user can override the flags by setting the CFLAGS environment
+#   variable. The user can also specify --enable-portable-binary in order to
+#   disable any optimization flags that might result in a binary that only
+#   runs on the host architecture.
+#
+#   Note also that the flags assume that ANSI C aliasing rules are followed
+#   by the code (e.g. for gcc's -fstrict-aliasing), and that floating-point
+#   computations can be re-ordered as needed.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_COMPILER_VENDOR,
+#   AX_GCC_ARCHFLAG, AX_GCC_X86_CPUID.

+# SYNOPSIS
+#
+#   AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
+#
+# DESCRIPTION
+#
+#   This macro tries to guess the "native" arch corresponding to the target
+#   architecture for use with gcc's -march=arch or -mtune=arch flags. If
+#   found, the cache variable $ax_cv_gcc_archflag is set to this flag and
+#   ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
+#   "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
+#   to add $ax_cv_gcc_archflag to the end of $CFLAGS.
+#
+#   PORTABLE? should be either [yes] (default) or [no]. In the former case,
+#   the flag is set to -mtune (or equivalent) so that the architecture is
+#   only used for tuning, but the instruction set used is still portable. In
+#   the latter case, the flag is set to -march (or equivalent) so that
+#   architecture-specific instructions are enabled.
+#
+#   The user can specify --with-gcc-arch=<arch> in order to override the
+#   macro's choice of architecture, or --without-gcc-arch to disable this.
+#
+#   When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
+#   called unless the user specified --with-gcc-arch manually.
+#
+#   Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
+#
+#   (The main emphasis here is on recent CPUs, on the principle that doing
+#   high-performance computing on old hardware is uncommon.)

+# SYNOPSIS
+#
+#   AX_GCC_X86_CPUID(OP)
+#
+# DESCRIPTION
+#
+#   On Pentium and later x86 processors, with gcc or a compiler that has a
+#   compatible syntax for inline assembly instructions, run a small program
+#   that executes the cpuid instruction with input OP. This can be used to
+#   detect the CPU type.
+#
+#   On output, the values of the eax, ebx, ecx, and edx registers are stored
+#   as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
+#   ax_cv_gcc_x86_cpuid_OP.
+#
+#   If the cpuid instruction fails (because you are running a
+#   cross-compiler, or because you are not using gcc, or because you are on
+#   a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
+#   is set to the string "unknown".
+#
+#   This macro mainly exists to be used in AX_GCC_ARCHFLAG.

+ * This is an implementation of famous boundary trace algorithm.
+ * See fractint documentation if you don't know what this means :)
+ *
+ * Here is two different implentation of this algorithm - one is faster
+ * and second is threadable.
+ *
+ * An faster one is quite usual implementation - get first uncalculated pixel,
+ * trace algorithm using labirinth "right hand rule" way (well, I currently
+ * use left hand rule) then trace same boundary again and fill. It is
+ * implemented in tracerectangle/tracecolor
+ *
+ * An threaded one follows description I sent to sci.fractals:
+ Hi
+ few weeks ago I asked for multithreaded algorithm for boundary trace
+ I received following reply by Paul Derbyshire

+ This method looks very interesting but has few serious problems.
+ Most significant probably is that it always caluclates pixels up
+ to distance 3 from boundary. Simple modification should lower it
+ to distance 2. But "right hand rule" based algorithm should actualy
+ calculate points just to distance 1. So I want to implement such alrogithm,
+ since number of caluclated points is still significant.
+
+ So I think I have to extend stack for two informations:
+ 1) direction
+ 2) color of boundary I am tracking(not color I am at)
+ and main algorithm should look like:
+ 1) detect color of current point
+ 2) look right. Is there same color? 
+ yes:add point at the right to stack and exit
+ is there boundary color?
+ no:we are meeting boundary with different color - so we need
+ to track this boundary too. add point at right to stack with oposite
+ direction and boundary color set to current color
+ 3) look forward: similiar scheme as to look right
+ 4) look left: again similiar
+ 5) exit
+
+ This hould trace boundaries to distance 1 (I hope) and do not miss anything.
+ Problem is that this algorithm never ends, since boundaries will be rescaned
+ again and again. So I need to add an caluclated array wich should looks like:
+ for every point has mask for all directions that were scaned+calculated mask
+ (set to 1 if pixel is already calculated)+inprocess mask(set to 1 if some
+ other processor is currently calculating it)
+
+ Scan masks should be set in thime when pixel is added to stack and pixel
+ should not be added in case that mask is already set. I don't this that locks
+ to this array is required since time spent by setting masks should be quite
+ small and possible race conditions should not be drastical(except recalculating
+ some point)
+
+ I was also thinking about perCPU queues. I think that one queue is OK,
+ it is simplier and should not take much more time(except it will be locked
+ more often but time spend in locked queue in comparsion to time spent
+ in rest should be so small so this should not be drastical for less than 10
+ procesors)
+
+ At the other hand - perCPU queues should have one advantage - each
+ cpu should own part of image and points from its part will be added to 
+ this cpu. This should avoid procesor cache conflict and speed up process.
+ At the other hand, when cpu's queue is empty, cpu will have to browse
+ others queues too and steal some points from other CPU, wich should introduce
+ some slowdown and I am not sure if this way will bring any improvement.
+
+ Other think that should vote for perCPU queue is fact, that in one CPU
+ queue should be more often situations when queue is empty since one procesor
+ is caluclating points and other has wait, since it had tendency to trace
+ just one boundary at the time. At the other hand, most of boundaries should
+ cross broders, so they should be added to queue at the initialization, so
+ this should be OK.
+
+ I am beginer to threds, SMP etc. So I looking for ideas, and suggestions
+ to improve this alg. (or design different one).
+ Also someone with SMP box, who should test me code is welcomed.
+ BTW whats is the average/maximal number of CPU in todays SMP boxes?
+
+ Please reply directly to my email:hubicka@paru.cas.cz
+
+ Thanks 
+ Honza
+ * This way is implemented in tracerectangle2/tracepoint. It is enabled
+ * just when threads are compiled in. Also when nthreads=1, old faster
+ * algorithm is used.
+ *
+ * Implementation notes:
+ * 1) I decided to use one queue instead of stack, since I expect, it will
+ *    have tendency to trace all boundaries at the time, not just one.
+ *    This will make queue bigger and reduce probability of situation, where
+ *    queue is empty and other processors has to wait for one, that is
+ *    calculating and should add something there (maybe :)
+ * 2) Stack (queue :) is used just when neccesary - in situations where queue
+ *    is quite full (there is more items than 10) procesor just continues in
+ *    tracing path it started. This reduces number of slow stack operations,
+ *    locks/unlocks, cache conflicts and other bad thinks. 
+ * 3) Just each fourth pixel should be added into queue
+ * 4) Foodfill algorithm should be avoided since colors at the boundaries
+ *    are always correct, we should simply go trought each scanline and when
+ *    pixel is uncalcualted, copy value from its left neighbor
+ *
+ * Current implementation has about 6% lower results than "fast" algorithm
+ * using one thread. When two threads enabled (at my one processor linux
+ * box) lock/unlock overhead eats next 8%, three threads eats next 1% :)

+   All comments preceded by F. are mine (Fabrice Premel premelfa@etu.utc.fr).
+   Tried to make code as efficient as possible.
+   Next to do is convert lim in a variable that would be updated sometimes
+   I'll try to make here a short explanation on periodicity checking :
+   first, we'll define 2 variables : whentosave and whenincsave, which are, respectively,
+   a measure of when we have to update saved values to be checked, and when to increase
+   interval between 2 updates, as if they're too close, we'll miss large periods.
+   We save Z at the beginning, and then we compare each new iteration with this Z, and if naerly
+   equal, we declare the suite to be periodic.
+   When ( iter mod whentosave ) == 0, we store a new value, and we repeat.
+
+   UNCOMPRESSed form is just an extension, with careful that if we only check whentosave
+   all 8 iterations, number of iterations must be well set at the begining.This is
+   done by adding a (iter&7) in the while statement preceeding then uncompressed
+   calculation. */
+
+/*F. : This is from then lim factor that depends all periodicity check spped : the bigger it is, the faster we
+   can detect periodicity, but the bigger it is, the more we can introduce errors.
+   I suggest a value of (maxx-minx)/(double)getmaxx for a classic Mandelbrot Set,
+   and maybe a lesser value for an extra power Mandelbrot.
+   But this should be calculated outter from here (ie each frame, for example), to avoid
+   new calculs */

+ * Mandelbrot's original formula is z=z^2+c which means
+ * z[next]=z[previous]^2+c.
+ * Here c is the pixel coordinates from the screen and z[0] is usually 0
+ * (if not perturbation was added.)
+ * In the following code z[previous] is described by (zre;zim)
+ * and z[next] will also be zre and zim.
+ * c is described by (pre;pim).
+ * Finally rp and ip are helper variables, mostly for checking the bailout
+ * (which usually means abs(z)>=4, see BTEST).
+ *
+ * Both basic operations and some other functions (c_mul, c_pow3, ...) can
+ * be used. For a "detailed" description refer to ../include/complex.h.
+ * 
+ * If you add/modify fractals, please note that struct formula_formulas
+ * (at line cca. 1300) should be also edited for proper initialization
+ * and for menu entries. However it is not self-explanatory, just copy-paste
+ * existing tables and give it a try.
+ *
+ * Finally, please also edit the calculateswitch function and
+ * the nmformulas constant (at the end of this file).

+Internationalization (i18n) in XaoS
+-----------------------------------
+
+Zoltan Kovacs <kovzol@math.u-szeged.hu>
+
+Last modification information:
+$Header: /home/jblang/XaoS-cvsbackup/XaoS/src/i18n/README,v 1.8 2008-04-21 05:48:44 kovzol Exp $
+
+
+
+1. INTRODUCTION
+
+As of version 3.1, i18n support is added to XaoS. This is done
+with the GNU gettext utility. In this first release only the menus
+and most internal strings can be translated, the old method in
+../../catalogs haven't changed yet.
+
+Note that i18n cannot be used if you don't have gettext installed
+on your system. I used gettext-0.10.37 which works greatly for Linux
+and gettext-0.10.40 for DOS version. You do not have to worry
+if you are running Linux: gettext is a standard package of most
+Linux installation.
+
+Bad news for Windows users: i18n does not work fully for Windows yet,
+only in DOS mode. In addition, some Windows support i18n in DOS mode,
+some of them not. (In fact in most Windows version I was not able to
+force i18n. I had to exit Windows and start native DOS mode. This should
+really work under Windows 95.) The main problem is that XaoS works
+with static dialogs and Win32 must be a bit rewritten to make
+it work.
+
+Unfortunately, under DOS some complex messages are not supported
+(press 'l' to check if your gettext version handles all types of
+message strings properly).
+
+
+2. HOW TO INSTALL A NEW LANGUAGE
+
+This will work only on Unix systems.
+
+* Edit ../../configure.in and add your language code into the LINGUAS
+variable. This is a 2 letter long code (e.g. "cs" for Czech, "de" for
+German).
+
+* Run autoconf.
+	
+* Type "./configure" in the directory ../.., then come back.
+
+* Type "make new-languages". This will generate a so-called .po-file
+  for you (e.g. "cs.po" or "de.po"). 
+
+* Edit the generated file manually. The first 15 lines should be filled in
+  properly, otherwise nothing will work in your language. The other
+  lines should be also filled in respectively. Note that you should
+  change the "msgstr" rows only. See the Hungarian language file,
+  "hu.po" for example. Important, that the first "#, fuzzy" line must be
+  removed.
+
+* Type a "make" to generate the so-called .mo-files. These files will be
+  installed later to the directory /usr/share/locale/ under Linux
+  and ../../locale under Windows/DOS systems. You should have
+  superuser rights to install them to their appropriate place with
+  the well known statement "make install".
+
+* That's all, start XaoS and enjoy it. ;-)
+
+* Please share your .po-file with the others! You may inform me that a
+  new language file was created by you. If it works, we will add it to
+  the CVS tree of XaoS as well.
+
+
+3. EXPERT'S GUIDE
+
+I'm not an expert, I just only want to share my little knowledge with you
+if you're interested:
+
+* To set up different languages and try out each one you probably have
+  to set the LC_ALL variable. E.g., I had to change it to de_DE or hu_HU
+  to test different languages. (On DOS I had to set the variable
+  LANG to de or hu, etc.)
+	
+* Read the gettext howto ("info gettext"). It's quite long, though.
+
+* To internationalize other texts in XaoS, you should edit first the 
+  variable CSOURCES in the makefile. Second, each "not static" string
+  in these C sources may be internationalized with the gettext()
+  function. See the existing tags for example. Again, please share
+  your modified code with us.
+
+* Gettext for autoconf is written using a non-standard (but working) way.
+  If you find an error, please send a bug report to me.
+	
+
+4. FUTURE PLANS
+
+XaoS i18n is not yet finished. I'm working on it in my spare time.
+Your help is also welcome.
+
+
+5. CONTRIBUTORS
+
+* Andreas Madritsch made the German translation and tested i18n very 
+  intensively. With his help I made lots of fixes in i18n stuff.
+
+* Martin Dozsa translated menus into Czech.
+
+* Ceser Perez contributed the Spanish translations.
+
+Thanks to everyone!
+
+
+6. IMPORTANT NOTES FOR MODERN LINUX SYSTEMS
+
+(Contributed by �. Fekete and Z. Kovács.)
+
+! Note: the information provided in this section is not valid anymore,
+! because XaoS 3.4 already support UTF-8 encodings natively. We don't
+! delete this section, however, for historical reasons. ;-)
+
+This section describes how to display Hungarian characters correctly in XaoS
+on Ubuntu 7.10. But this may be help on other systems, too. The section should
+be useful for other non-English users as well.
+
+XaoS displays Hungarian characters wrongly because the locale is not set well.
+
+1.) So check the output of the following command:
+
+$ locale
+
+and if the locale character set is not ISO-8859-2,
+then this should be the problem. In this case,
+
+2.) check if your locale is in /var/lib/locales/supported.d/local
+(and /var/lib/locales/supported.d/*) and if not, write a line describing
+
+your locale to the end of these files. That line should be one line of
+the file /usr/share/i18n/SUPPORTED, for example:
+
+hu_HU ISO-8859-2
+
+3.) Run
+
+$ sudo dpkg-reconfigure locales
+
+entering your administrative password.
+
+4.) Before running xaos, give this locale to the LC_ALL environment
+variable, for example:
+
+$ export LC_ALL=hu_HU
+
+5.) You should be able to run xaos with the menu in readable format,
+but the letters õ and û are still not good in the terminal. If you want
+
+to change that and are using gnome-terminal, set the character encoding
+to Central European (ISO-8859-2) in the Terminal menu.

+     *
+     * The Mac OS X driver requires a 32-bit rgb mask where the most significant
+     * byte is on (e.g., 0xffffff00). This exposed a bug in the interpol macro
+     * that resulted in distorted colors for the smooth coloring modes.
+     * If the interpol macro is applied to such a mask, it causes an overflow
+     * of the 32-bit int, and the left-most color byte is lost.
+     *
+     * I added shiftinterpol macro to handle such masks. It shifts everything 1 
+     * byte to the right, performs the calculation, and then shifts everything 
+     * back 1 byte to the left when it is done.
+     *
+     * I also created the safeinterpol macro which detects if the most
+     * signficant byte in the mask is on, and uses the shiftinterpol macro if
+     * so, or the orignal interpol macro if not.
+     *
+     * I then modified the interpoltype macro to use the safeinterpol macro
+     * instead of the interpol macro directly.

+   _control87 changes floating-point control word.
+
+   Declaration:
+   ------------
+     unsigned short _control87(unsigned short newcw, unsigned short mask);
+
+   Remarks:
+   --------
+  _control87 retrieves or changes the floating-point control word.
+
+  The floating-point control word is an unsigned short that specifies the
+  following modes in the 80x87 FPU:
+   o  allowed exceptions
+   o  infinity mode
+   o  rounding mode
+   o  precision mode
+
+  Changing these modes allows you to mask or unmask floating-point exceptions.
+
+  _control87 matches the bits in mask to the bits in newcw.
+
+  If any mask bit = 1, the corresponding bit in newcw contains the new value
+  for the same bit in the floating-point control word.
+
+  If mask = 0000, _control87 returns the floating-point control word without
+  altering it.
+
+   Examples:
+   ---------
+  Switching to projective infinity mode:
+     _control87(IC_PROJECTIVE, MCW_IC);
+
+  Disabling all exceptions:
+     _control87(MCW_EM, MCW_EM);
+
+   Return Value:
+   -------------
+  The bits in the value returned reflect the new floating-point control word.

+XaoS for Mac OS X (Cocoa)
+Build Instructions
+
+By J.B. Langston III
+
+Here are instructions for getting the XaoS Xcode project to build successfully 
+assuming you have downloaded a released source tarball or gotten the source 
+from CVS:
+
+A) Build dependencies
+
+    1) Download the latest libpng from 
+
+        ftp://ftp.simplesystems.org/pub/libpng/png/src/
+
+    2) Configure libpng for universal binaries with the following command:
+
+          env CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc -mmacosx-version-min=10.4" \
+              LDFLAGS="-arch i386 -arch ppc" \
+	          ./configure --prefix=$XAOS_ROOT/src/ui/ui-drv/cocoa/thirdparty --disable-dependency-tracking
+	   
+	   Be sure to replace $XAOS_ROOT with the root of your XaoS source folder.
+	   
+       For more information about building open source libraries as universal binaries:	   
+	   http://developer.apple.com/technotes/tn2005/tn2137.html
+	
+	3) Make and install libpng:
+	   
+	   make && make install
+	   
+	4) Download the latest gsl from 
+
+       ftp://ftp.gnu.org/gnu/gsl/
+       
+    5) Repeat steps 2 and 3 for gsl
+    
+	6) Download the latest gettext from 
+
+       ftp://ftp.gnu.org/gnu/gettext/
+
+    7) Repeat steps 2 and 3 for gettext
+	
+B) Build XaoS
+
+    You should now be able to build XaoS from the Xcode project.
+
+Have fun! If you have questions, feel free to e-mail me: jb-langston at austin dot rr dot com

+\b \cf0 About\
+\pard\pardeftab720\sa80\ql\qnatural
+
+\b0 \cf0 XaoS is an incredible program that lets you explore fractals by zooming in and out in real time.\'a0 If you\'92ve only used static fractal viewers like Fractint or UltraFractal before, zooming into a fractal as a real time animation is incredible.\'a0 XaoS was originally written by Jan Hubicka and Thomas Marsh, and is currently maintained by Zoltan Kovacs.  I contributed the Mac OS X user interface and made binaries available for ease of use. XaoS is free software available under the terms of the GNU General Public License.\

+
+\b \cf0 Installation and Usage\
+\pard\pardeftab720\ql\qnatural
+
+\b0 \cf0 After downloading the XaoS binary, just copy it to your applications folder and run the program. Basic usage is really pretty simple.\'a0\

+{\listtext	\'95	}To zoom back out, hold down the control key and click.\'a0 Or, right click with a two-button mouse.\'a0\
+{\listtext	\'95	}To pan, hold down the shift key and drag. On a three-button mouse, drag with the center button.\'a0 If you have a mouse with a scroll wheel, pressing down on the scroll wheel usually works like the center button.\
+{\listtext	\'95	}To go full-screen, select UI->Drivers->Mac OS X Fullscreen Driver from the menu.  In full screen mode, the menu is only displayed when you move the mouse near the top of the screen. After going full screen, you can quit by pressing \uc0\u8984 Q, or you can go back to windowed mode by selecting UI->Drivers->Mac OS X Windowed Driver.\

+\b \cf0 Revision History\
+\pard\pardeftab720\sa80\ql\qnatural
+
+\b0 \cf0 3.4\
+Release Date: 6/1/2008\
+\pard\tx560\pardeftab720\ql\qnatural
+\cf0 \
+This is a huge release for Mac users. The Mac user interface has been completely rewritten in Cocoa and improved in a number of ways:\
+\
+\pard\tx220\tx720\pardeftab720\li720\fi-720\sa80\ql\qnatural
+\ls3\ilvl0\cf0 {\listtext	\'95	}Standard Aqua dialog boxes instead of the strange-looking Unixy things in previous versions. Fields in dialog boxes now support cut and paste as you would expect.\
+{\listtext	\'95	}Pop-up menus are now displayed using standard Aqua menus\
+{\listtext	\'95	}Menu bar in full-screen mode is now the standard Mac OS X menu bar. It automatically slides into view when you move your mouse to the top of the screen and slides out when you move away from it.\
+{\listtext	\'95	}XaoS now has a standard Aqua about dialog box, which displays links to license and credits in help file.\
+{\listtext	\'95	}Help is now displayed via Mac OS X's standard help viewer. Tutorials can still be launched via links in  the help viewer.\
+{\listtext	\'95	}Support for opening xpf (Saved Position) and xaf (Saved Animation) files directly from Finder via drag and drop and by double-clicking.  XaoS now includes its own document icon for these files as well.\
+{\listtext	\'95	}Support for basic AppleScriptability via the standard script dictionary. Includes things like opening files and manipulating the window, but no XaoS-specific functionality.\
+{\listtext	\'95	}Support for panning the fractal with the mouse scroll wheel or trackpad two-finger gestures.\
+\pard\tx560\pardeftab720\ql\qnatural
+\cf0 \
+In addition to the user interface improvements, XaoS for Mac has the following improvements:\
+\
+\pard\tx220\tx720\pardeftab720\li720\fi-720\sa80\ql\qnatural
+\ls4\ilvl0\cf0 {\listtext	\'95	}Now uses greater precision (long double) for calculations to enable much deeper zooms.\
+{\listtext	\'95	}In addition to English, XaoS for Mac OS X now supports the following languages: Czech, French, German, Hungarian, Italian, Romanian, and Spanish.\
+{\listtext	\'95	}Integration with Stone Design's Videator (http://stone.com/Videator/). XaoS can now send live a live video stream to Videator, which can then do post-processing using Mac OS X's core video technology. This is great for VJing (live video performance art). See http://stone.com/Videator/VJ.html for more details.\
+{\listtext	\'95	}New Italian translation courtesy of Sergio Zanchetta\
+{\listtext	\'95	}Updated German translation by Andreas Madritsch\
+{\listtext	\'95	}Bug fix to prevent Edge Detection and Pseudo 3D filter from rendering the image completely black.\
+{\listtext	\'95	}Bug fix to prevent garbled characters when using non-English languages on modern systems using UTF-8\
+{\listtext	\'95	}Bug fix to prevent XaoS from crashing after using the Render Animation functionality\
+{\listtext	\'95	}Bug fix to prevent incorrect colors on smooth coloring modes with certain video modes\

+
+    BUGS
+    
+    - Fix crash after animation rendering
+      
+      Analysis: changes introduced for sffe made the uih variable from ui.c
+      global in ui.h so that the sffe parser can be accessed from custom
+      formula code in formulas.c. Uih was previously declared static in render.c
+      because the animation renderer maintains its own context.  SFFE changed 
+      this from static to extern so the uih in render.c was pointing to the same
+      uih in ui.c, instead of to a different structure.  When animations were
+      rendered, the uih in ui.h got clobbered, and the next function that tried
+      to use it caused a segfault.
+      
+      Fix: 
+      1. Change name of global uih pointer defined in ui.h from uih to globaluih.
+      2. Change sffe code to access globaluih pointer instead of uih
+      3. Add code to main function to set both uih and globaluih to point at the same structure
+      4. Change code in cocoa driver to use globaluih as well
+      
+    - Fix bug that causes XaoS to crash when using non-native (ugly) dialog
+      code for Render Animation dialog with open file dialog for basename
+      
+      Analysis: There was a loop in ui_buildfile in dialog.c, that tried to 
+      find a "*" in the default filename, and if it didn't find one, it would 
+      run right off the end of the buffer and continue until a seg fault occurred.
+      
+      Fix: the loop now checks for both "*" or a nul terminator as the exit
+      condition.  If it doesn't find an asterisk, it still stops at the end
+      of the string.
+      
+    - Make custom dialog boxes slide out of view before executing menu function
+
+      This prevents the dialog from hanging around after clicking OK during long
+      running operations such as rendering animations
+      
+    - Add code to prevent rendering animation if absolute path is not specified
+      for Basename.  This prevents files from being accidentally written to the
+      hard drive's root directory
+      
+2008-04-23
+
+    I18N
+    
+    - Changes to -initLocale: do not overwrite LANG if it is already set
+    
+    - Added AppController.m and CustomDialog.m in i18n/Makefile.in.in
+    
+    - Regenerated po and pot files with new strings from cocoa driver

+    MISC
