59 * 7 6/30/99 5:53p Dave
60 * Put in new anti-camper code.
62 * 6 6/03/99 6:37p Dave
63 * More TNT fun. Made perspective bitmaps more flexible.
65 * 5 6/02/99 6:18p Dave
66 * Fixed TNT lockup problems! Wheeeee!
68 * 4 12/18/98 1:13a Dave
69 * Rough 1024x768 support for Direct3D. Proper detection and usage through
72 * 3 10/09/98 2:57p Dave
73 * Starting splitting up OS stuff.
75 * 2 10/08/98 2:38p Dave

80 * Fix connection speed bug on standalone server.
82 * 117 5/24/98 2:28p Hoffoss
83 * Because we never really care about if the left or the right shift or
84 * alt key was used, but rather than either shift or alt was used, made

100 * 112 5/15/98 3:36p John
101 * Fixed bug with new graphics window code and standalone server. Made
