+ *    Revision 1.19  2002/03/16 23:54:06  jongfoster
+ *    Adding graceful termination feature, to help look for memory leaks.
+ *    If you enable this (which, by design, has to be done by hand
+ *    editing config.h) and then go to http://i.j.b/die, then the program

+ *     - Changed built-in images from GIF to PNG
+ *       (with regard to Unisys patent issue)
+ *     - Added a 4x4 pattern PNG which is less intrusive
+ *       than the logo but also clearly marks the deleted banners
