* Revision 1.12 2004/03/07 23:07:20 Kazan
|
|
* [Incomplete] Readd of Software renderer so Standalone server works
|
|
*
|
|
* Revision 1.11 2004/03/05 21:19:39 Kazan
|
|
* Fixed mission validation (was returning false positives)
|
|
*
|
|
* Revision 1.10 2004/03/05 09:01:56 Goober5000
|
|
* Uber pass at reducing #includes
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.9 2004/02/21 00:59:43 Kazan
|
|
* FS2NETD License Comments
|
|
*
|
|
* Revision 1.8 2004/02/04 09:02:42 Goober5000
|
|
* got rid of unnecessary double semicolons
|
|
* --Goober5000
|
|
*
|
|
* Revision 1.7 2003/11/13 03:59:52 Kazan
|
|
* PXO_SID changed from unsigned to signed
|
|
*
|
|
* Revision 1.6 2003/11/11 02:15:42 Goober5000
|
|
* ubercommit - basically spelling and language fixes with some additional
|
|
* warnings disabled
|
|
* --Goober5000
|
|

* --Goober5000
|
|
*
|
|
* Revision 1.4 2003/11/06 20:22:05 Kazan
|
|
* slight change to .dsp - leave the release target as fs2_open_r.exe already
|
|
* added myself to credit
|
|
* killed some of the stupid warnings (including doing some casting and commenting out unused vars in the graphics modules)
|
|
* Release builds should have warning level set no higher than 2 (default is 1)
|
|
* Why are we getting warning's about function selected for inline expansion... (killing them with warning disables)
|
|
* FS2_SPEECH was not defined (source file doesn't appear to capture preproc defines correctly either)
|
|
*
|
|
* Revision 1.3 2003/10/13 05:57:47 Kazan
|
|
* Removed a bunch of Useless *_printf()s in the rendering pipeline that were just slowing stuff down
|
|
* Commented out the "warning null vector in vector normalize" crap since we don't give a rats arse
|
|
* Added "beam no whack" flag for beams - said beams NEVER whack
|
|
* Some reliability updates in FS2NetD
|
|
*
