/* Some help for the brave ones. :-)
 *
 * 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).
 *
