* $Logfile: /Freespace2/code/OsApi/OsApi.cpp $
* $Revision: 2.2 $
* $Date: 2002-08-01 01:41:09 $
* $Author: penguin $
*
* Low level Windows code
*
* $Log: not supported by cvs2svn $
* Revision 2.1 2002/07/07 19:55:59 penguin
* Back-port to MSVC
*
* Revision 2.0 2002/06/03 04:10:40 penguin
* Warpcore CVS sync
*
* Revision 1.3 2002/06/03 03:42:13 mharris
* fAppActive is now set correctly; translate some keyboard scancodes
* that appear to be different between SDL and Win32; combine KEYDOWN
* and KEYUP events.
*
* Revision 1.2 2002/05/21 15:45:58 mharris
* init outwnd in debug mode; added SDL support
*
* Revision 1.1 2002/05/16 00:47:21 mharris
* New version of OsApi files for Unix variants.
*
* Revision 1.2 2002/05/09 13:52:01 mharris
* debug_int3() calls abort()
*
* Revision 1.1 2002/05/02 18:03:12 mharris
* Initial checkin - converted filenames and includes to lower case
*
*
* 7 6/30/99 5:53p Dave
* Put in new anti-camper code.
*
* 6 6/03/99 6:37p Dave
* More TNT fun. Made perspective bitmaps more flexible.
*
* 5 6/02/99 6:18p Dave
* Fixed TNT lockup problems! Wheeeee!
*
* 4 12/18/98 1:13a Dave
* Rough 1024x768 support for Direct3D. Proper detection and usage through
* the launcher.
*
* 3 10/09/98 2:57p Dave
* Starting splitting up OS stuff.
*
* 2 10/08/98 2:38p Dave
* Cleanup up OsAPI code significantly. Removed old functions, centralized
* registry functions.
*
* 118 7/10/98 5:04p Dave
* Fix connection speed bug on standalone server.
*
* 117 5/24/98 2:28p Hoffoss
* Because we never really care about if the left or the right shift or
* alt key was used, but rather than either shift or alt was used, made
* both map to the left one. Solves some problems, causes none.
*
* 116 5/18/98 9:22p John
* Took out the annoying tab check.
*
* 115 5/18/98 11:17a John
* Fixed some bugs with software window and output window.
*
* 114 5/16/98 2:20p John
* Changed the os_suspend and resume to use a critical section to prevent
* threads from executing rather than just suspending the thread. Had to
* make sure gr_close was called before os_close.
*
* 113 5/15/98 4:49p John
*
* 112 5/15/98 3:36p John
* Fixed bug with new graphics window code and standalone server. Made
* hwndApp not be a global anymore.
*
* 111 5/14/98 5:42p John
* Revamped the whole window position/mouse code for the graphics windows.
*
* 110 5/04/98 11:08p Hoffoss
* Expanded on Force Feedback code, and moved it all into Joy_ff.cpp.
* Updated references everywhere to it.
*
