 * Revision 1.20  2000/10/29 22:55:01  weimer
 * networking consistency checks (you must have the same number of doodads):
 * special hotkey 'f' in main menu toggles full screen mode
 * added depth specification on the command line
 * automatically search for the darkest non-black color ...
 *
 * Revision 1.19  2000/10/29 21:23:28  weimer

 *
 * Revision 1.12  2000/10/18 23:57:49  weimer
 * general fixup, color changes, display changes.
 * Notable: "Safe" Blits and Updates now perform "clipping". No more X errors,
 * we hope!
 *
 * Revision 1.11  2000/10/18 02:04:02  weimer
 * playability changes ...
 *
 * Revision 1.10  2000/10/13 15:41:53  weimer
 * revamped AI support, now you can pick your AI and have AI duels (such fun!)
 * the mighty Aliz AI still crashes a bit, though ... :-)
 *
 * Revision 1.9  2000/10/12 22:21:25  weimer
 * display changes, more multi-local-play threading (e.g., myScore ->
 * Score[0]), that sort of thing ...

 * added "AI" support and walking radio menus for initial game configuration
 *
 * Revision 1.5  2000/09/09 17:05:35  wkiri
 * Hideous log changes (Wes: how dare you include a comment character!)
 *
 * Revision 1.4  2000/09/09 16:58:27  weimer
 * Sweeping Change of Ultimate Mastery. Main loop restructuring to clean up
 * main(), isolate the behavior of the three game types. Move graphic files
 * into graphics/-, style files into styles/-, remove some unused files,
 * add game flow support (breaks between games, remembering your level within
 * this game), multiplayer support for the event loop, some global variable
 * cleanup. All that and a bag of chips!
 *
 * Revision 1.3  2000/09/04 22:49:51  wkiri
 * gamemenu now uses the new nifty menus.  Also, added delete_menu.
 *
 * Revision 1.2  2000/09/04 19:48:02  weimer
 * interim menu for choosing among game styles, button changes (two states)
 *
