56 * 7 6/30/99 5:53p Dave
57 * Put in new anti-camper code.
59 * 6 6/03/99 6:37p Dave
60 * More TNT fun. Made perspective bitmaps more flexible.
62 * 5 6/02/99 6:18p Dave
63 * Fixed TNT lockup problems! Wheeeee!
65 * 4 12/18/98 1:13a Dave
66 * Rough 1024x768 support for Direct3D. Proper detection and usage through
69 * 3 10/09/98 2:57p Dave
70 * Starting splitting up OS stuff.
72 * 2 10/08/98 2:38p Dave
73 * Cleanup up OsAPI code significantly. Removed old functions, centralized
76 * 118 7/10/98 5:04p Dave
77 * Fix connection speed bug on standalone server.
79 * 117 5/24/98 2:28p Hoffoss
80 * Because we never really care about if the left or the right shift or
81 * alt key was used, but rather than either shift or alt was used, made

91 * Changed the os_suspend and resume to use a critical section to prevent

93 * make sure gr_close was called before os_close.

97 * 112 5/15/98 3:36p John
98 * Fixed bug with new graphics window code and standalone server. Made
99 * hwndApp not be a global anymore.
