 *
 * header file for PCX utilities
 *
 * $Log: not supported by cvs2svn $
 * Revision 2.6  2005/07/13 03:35:34  Goober5000
 * remove PreProcDefine #includes in FS2
 * --Goober5000
 *
 * Revision 2.5  2005/02/04 10:12:32  taylor
 * merge with Linux/OSX tree - p0204
 *
 * Revision 2.4  2004/10/31 22:00:57  taylor
 * new bmpman merge support, add PreProcDefines.h a few new places
 *
 * Revision 2.3  2004/08/11 05:06:32  Kazan
 * added preprocdefines.h to prevent what happened with fred -- make sure to make all fred2 headers include this file as the _first_ include -- i have already modified fs2 files to do this
 *
 * Revision 2.2  2003/11/19 20:37:24  randomtiger
 * Almost fully working 32 bit pcx, use -pcx32 flag to activate.
 * Made some commandline variables fit the naming standard.
 * Changed timerbar system not to run pushes and pops if its not in use.
 * Put in a note about not uncommenting asserts.
 * Fixed up a lot of missing POP's on early returns?
 * Perhaps the motivation for Assert functionality getting commented out?
 * Fixed up some bad asserts.
 * Changed nebula poofs to render in 2D in htl, it makes it look how it used to in non htl. (neb.cpp,1248)
 * Before the poofs were creating a nasty stripe effect where they intersected with ships hulls.
 * Put in a special check for the signs of that D3D init bug I need to lock down.
 *
 * Revision 2.1  2002/08/01 01:41:09  penguin
 * The big include file move
 *
 * Revision 2.0  2002/06/03 04:02:27  penguin
 * Warpcore CVS sync
 *
 * Revision 1.1  2002/05/02 18:03:12  mharris
 * Initial checkin - converted filenames and includes to lower case
 *
 * 
 * 6     8/10/99 6:54p Dave
 * Mad optimizations. Added paging to the nebula effect.
 * 
 * 5     2/05/99 12:52p Dave
 * Fixed Glide nondarkening textures.
 * 
 * 4     12/01/98 4:46p Dave
 * Put in targa bitmap support (16 bit).
 * 
 * 3     11/30/98 1:07p Dave

 * Initial checkin.
 * 
 * 1     10/07/98 10:50a Dave
 * 
 * 7     9/03/97 4:32p John
 * changed bmpman to only accept ani and pcx's.  made passing .pcx or .ani
 * to bm_load functions not needed.   Made bmpman keep track of palettes
 * for bitmaps not mapped into game palettes.
 * 
 * 6     11/26/96 9:28a Allender
 * get palette info when getting pcx info
 * 
 * 5     11/18/96 12:36p John
 * Added code to dump screen to a PCX file.
 * 
 * 4     11/13/96 4:51p Allender
 * started overhaul of bitmap manager.  bm_load no longer actually load
 * the data, only the info for the bitmap.  Locking the bitmap now forces
 * load when no data present (or will if bpp changes)
