+ * 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.
