+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.

+Animate view
+============
+
+**Syntax**:(animateview float float float float)
+
+This function is almost identical to function :ref:`view <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.

+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).

+==========
+
+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.

+Basic Controls
+==============
+
+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:
+
+========================= ================================== =========================
+Action Mouse Button Mac Equivalent
+========================= ================================== =========================
+Zoom in :kbd:`Left` :kbd:`Click`
+Zoom out :kbd:`Right` :kbd:`Ctrl+Click`
+Pan :kbd:`Center` or :kbd:`Left+Right` :kbd:`Shift+Click`
+========================= ================================== =========================
+
+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

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

+**Syntax**:(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 :ref:`palette emulation filter <palettef>` to make it possible.

+
+In the user interface, colors can also be cycled in the opposite direction with

+To control the cycling speed, you coan use arrow keys or the "**Color cycling
+speed**" function.
+

+=========================
+
+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.

+
+The driver supports only hicolor and truecolor modes. There is no support for

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

+**Syntax**:(fastmode keyword)
+
+XaoS performs many optimizations, but fairly often this is not enough. In order

+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.
+

+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) \ No newline at end of file

+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.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+```````````````````````````````````````````````````````````````
+
+1. 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.
+
+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
+
+ 0 (default)
+
+1
+

+

+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)
+ (line 'scaled 0.3 0.5 0.3 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.
+

+Outside coloring mode
+=====================
+
+**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
+
+ iter+imag
+

+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.

+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.
+

+
+**Syntax**:(autorotate bool)
+
+Use this function to enable continuous rotation. In the scripting language you

+
+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:
+

+
+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.

+
+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.

+<uimandelbrot>`.

+====
+
+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.

+
+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`:
+ http://ffmpeg.mplayerhq.hu/faq.html#SEC12
+
+mencoder (part of mplayer)

+ http://www.mplayerhq.hu/
+
+.. _`mencoder 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. 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.

+============
+
+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 :ref:`DirectX <dX-window>` API.

+Context-Sensitive Help
+----------------------
+
+XaoS provides context-sensitive help from many areas of the user interface.
+If you are writing documentation about some command in the user interface,
+you must provide a target in order to make context sensitive help work.
+Place an internal hyperlink target in front of the section describing the
+command using the name of the command in the XaoS function registry, like so::

+Tutorials
+---------
+
+XaoS's documentation introduces an interpreted text role to reference
+tutorials. To reference a tutorial from the documentation, write
+``:tutor:`title <filename.xaf>```. This will refer to the tutorial
+*filename.xaf* using the text *title*. Depending on the format of the
+output, this may generate a link that will launch the referenced tutorial
+in XaoS, or it may just format the title in a different font.
