* 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.
