 * When shown ifs, Diana Rose (4 years old) said, "It looks like dancing."
 *
 * Revision History:
 * 13-Dec-2003: Added some goom specific stuffs (to make ifs a VisualFX).
 * 11-Apr-2002: jeko@ios-software.com: Make ifs.c system-indendant. (ifs.h added)
 * 01-Nov-2000: Allocation checks
 * 10-May-1997: jwz@jwz.org: turned into a standalone program.
 *              Made it render into an offscreen bitmap and then copy
 *              that onto the screen, to reduce flicker.
