*
* Header file for 2d primitives.
*
* $Log: not supported by cvs2svn $
* Revision 2.84 2007/01/10 01:44:39 taylor
* add support for new IBX format which can support up to UINT_MAX worth of verts (NOTE: D3D code still needs to be made compatible with this!!)
*
* Revision 2.83 2007/01/07 13:13:38 taylor
* cleanup various bits of obsolete or unused code
*
* Revision 2.82 2006/11/06 05:42:44 taylor
* various bits of cleanup (slight reformatting to help readability, remove old/dead code bits, etc.)
* deal with a index_buffer memory leak that Valgrind has always complained about
* make HTL model buffers dynamic (get rid of MAX_BUFFERS_PER_SUBMODEL)
* get rid of MAX_BUFFERS
* make D3D vertex buffers dynamic, like OGL has already done
*
* Revision 2.81 2006/10/06 09:56:42 taylor
* clean up some old software rendering stuff that we don't use any longer
* remove grzbuffer.*, since all it did was give us 3 variables, which were moved to 2d.*
*
* Revision 2.80 2006/09/11 06:36:38 taylor
* clean up the grstub mess (for work on standalone server, and just for sanity sake)
* move color and shader functions to 2d.cpp since they are exactly the same everywhere
* don't bother with the function pointer for gr_set_font(), it's the same everywhere anyway
*
* Revision 2.79 2006/05/27 17:07:48 taylor
* remove grd3dparticle.* and grd3dbatch.*, they are obsolete
* allow us to build without D3D support under Windows (just define NO_DIRECT3D)
* clean up TMAP flags
* fix a couple of minor OpenGL state change issues with spec and env map rendering
* make sure we build again for OS X (OGL extension functions work a little different there)
* render targets always need to be power-of-2 to avoid incomplete buffer issues in the code
* when we disable culling in opengl_3dunlit be sure that we re-enable it on exit of function
* re-fix screenshots
* add true alpha blending support (with cmdline for now since the artwork has the catch up)
* draw lines with float positioning, to be more accurate with resizing on non-standard resolutions
* don't load cubemaps from file for D3D, not sure how to do it anyway
* update geometry batcher code, memory fixes, dynamic stuff, basic fixage, etc.
*
* Revision 2.78 2006/05/13 07:29:52 taylor
* OpenGL envmap support
* newer OpenGL extension support
* add GL_ARB_texture_rectangle support for non-power-of-2 textures as interface graphics
* add cubemap reading and writing support to DDS loader
* fix bug in DDS loader that made compressed images with mipmaps use more memory than they really required
* add support for a default envmap named "cubemap.dds"
* new mission flag "$Environment Map:" to use a pre-existing envmap
* minor cleanup of compiler warning messages
* get rid of wasteful math from gr_set_proj_matrix()
* remove extra gr_set_*_matrix() calls from starfield.cpp as there was no longer a reason for them to be there
* clean up bmpman flags in reguards to cubemaps and render targets
* disable D3D envmap code until it can be upgraded to current level of code
* remove bumpmap code from OpenGL stuff (sorry but it was getting in the way, if it was more than copy-paste it would be worth keeping)
* replace gluPerspective() call with glFrustum() call, it's a lot less math this way and saves the extra function call
*
* Revision 2.77 2006/04/20 06:32:01 Goober5000
* proper capitalization according to Volition
*
* Revision 2.76 2006/04/15 00:13:22 phreak

* some basic lighting code cleanup
*
* Revision 2.74 2006/01/20 17:15:16 taylor

* gr_render_buffer shouldn't be returning values if it's supposed to return void
*
* Revision 2.71 2006/01/18 16:14:04 taylor
* allow gr_render_buffer() to take TMAP flags
* let gr_render_buffer() render untextured polys (OGL only until some D3D people fix it on their side)
* add MR_SHOW_OUTLINE_HTL flag so we easily render using HTL mode for wireframe views
* make Interp_verts/Interp_norms/etc. dynamic and get rid of the extra htl_* versions
*
* Revision 2.70 2006/01/12 17:42:56 wmcoolmon
* Even more scripting stuff.
*
* Revision 2.69 2005/12/29 08:08:33 wmcoolmon
* Codebase commit, most notably including objecttypes.tbl
*
* Revision 2.68 2005/12/29 00:52:57 phreak
* changed around aabitmap calls to accept a "mirror" parameter. defaults to false, and is only true for mirrored briefing icons.
* If the mirror param is true, then the picture is mirrored about the y-axis so left becomes right and vice versa.

* save the original gamma ramp on OGL init so that it can be restored on exit
*
* Revision 2.63 2005/07/18 03:44:00 taylor
* cleanup hudtargetbox rendering from that total hack job that had been done on it (fixes wireframe view as well)
* more non-standard res fixing
* - I think everything should default to resize now (much easier than having to figure that crap out)
* - new mouse_get_pos_unscaled() function to return 1024x768/640x480 relative values so we don't have to do it later
* - lots of little cleanups which fix several strange offset/size problems
* - fix gr_resize/unsize_screen_pos() so that it won't wrap on int (took too long to track this down)
*

* fixes various problems and is past time to make the switch
*
* Revision 2.58 2005/04/24 12:56:42 taylor
* really are too many changes here:
* - remove all bitmap section support and fix problems with previous attempt
* ( code/bmpman/bmpman.cpp, code/bmpman/bmpman.h, code/globalincs/pstypes.h,

*
* Revision 2.57 2005/04/24 03:02:43 wmcoolmon

*
* Revision 2.56 2005/04/24 02:38:31 wmcoolmon

*
* Revision 2.51 2005/03/16 01:35:58 bobboau
* added a geometry batcher and implemented it in sevral places
* namely: lasers, thrusters, and particles,

*
* Revision 2.21 2004/02/15 03:04:25 bobboau
* fixed bug involving 3d shockwaves, note I wasn't able to compile the directshow file, so I ifdefed everything to an older version,
* you shouldn't see anything diferent, as the ifdef should be set to the way it should be, if it isn't you will get a warning mesage during compile telling you how to fix it
*
* Revision 2.20 2004/02/14 00:18:31 randomtiger
* Please note that from now on OGL will only run with a registry set by Launcher v4. See forum for details.
* OK, these changes effect a lot of file, I suggest everyone updates ASAP:
* Removal of many files from project.
* Removal of meanless .
_poly variable.
* Removal of glide, directdraw, software modules all links to them, and all code specific to those paths.
* Removal of redundant Fred paths that arent needed for Fred OGL.
* Have seriously tidied the graphics initialisation code and added generic non standard mode functionality.
* Fixed many D3D non standard mode bugs and brought OGL up to the same level.
* Removed texture section support for D3D8, voodoo 2 and 3 cards will no longer run under fs2_open in D3D, same goes for any card with a maximum texture size less than 1024.
*
* Revision 2.19 2004/01/21 17:33:47 phreak
* added MAX_DRAW_DISTANCE constant
*

* several other small fixes
*
* Revision 2.13 2003/10/27 23:04:21 randomtiger
* Added -no_set_gamma flags
* Fixed up some more non standard res stuff
* Improved selection of device type, this includes using a pure device when allowed which means dev should not use Get* functions in D3D
* Made fade in credits work
* Stopped a call to gr_reser_lighting() in non htl mode when the pointer was NULL, was causing a crash loading a fogged level
* Deleted directx8 directory content, has never been needed.
*
* Revision 2.12 2003/10/25 03:26:39 phreak
* fixed some old bugs that reappeared after RT committed his texture code
*
* Revision 2.11 2003/10/24 17:35:05 randomtiger
* Implemented support for 32bit TGA and JPG for D3D
* Also 32 bit PCX, but it still has some bugs to be worked out
* Moved convert_24_to_16 out of the bitmap pfunction structures and into packunpack.cpp because thats the only place that uses it.
*
* Revision 2.10 2003/10/23 18:03:24 randomtiger
* Bobs changes (take 2)
*
* Revision 2.9 2003/10/21 18:23:15 phreak
* added gr_flip_window back in. its used in FRED

*
* Revision 2.6 2003/10/13 19:39:19 matt
* prelim reworking of lighting code, dynamic lights work properly now
* albeit at only 8 lights per object, although it looks just as good as
* the old software version --Sticks
*
* Revision 2.5 2003/10/10 03:59:40 matt
* Added -nohtl command line param to disable HT&L, nothing is IFDEFd
* out now. -Sticks
*
* Revision 2.4 2003/09/26 14:37:14 bobboau
* commiting Hardware T&L code, everything is ifdefed out with the compile flag HTL
* still needs a lot of work, ubt the frame rates were getting with it are incredable
* the biggest problem it still has is a bad lightmanegment system, and the zbuffer
* doesn't work well with things still getting rendered useing the sofware pipeline, like thrusters,
* and weapons, I think these should be modifyed to be sent through hardware,
* it would be slightly faster and it would likely fix the problem
*
* also the thruster glow/particle stuff I did is now in.
*
* Revision 2.3 2003/07/04 02:27:48 phreak
* added support for cloaking.
* i will need to contact someone who knows d3d to get this to work
*
* Revision 2.2 2003/03/18 10:07:02 unknownplayer
* The big DX/main line merge. This has been uploaded to the main CVS since I can't manage to get it to upload to the DX branch. Apologies to all who may be affected adversely, but I'll work to debug it as fast as I can.
*
* Revision 2.1.2.5 2002/11/09 19:28:15 randomtiger
*
* Fixed small gfx initialisation bug that wasnt actually causing any problems.
* Tided DX code, shifted stuff around, removed some stuff and documented some stuff.
*
* Revision 2.1.2.4 2002/11/04 16:04:20 randomtiger
*
* Tided up some bumpman stuff and added a few function points to gr_screen. - RT
*
* Revision 2.1.2.3 2002/11/04 03:02:28 randomtiger
*
* I have made some fairly drastic changes to the bumpman system. Now functionality can be engine dependant.
* This is so D3D8 can call its own loading code that will allow good efficient loading and use of textures that it desparately needs without
* turning bumpman.cpp into a total hook infested nightmare. Note the new bumpman code is still relying on a few of the of the old functions and all of the old bumpman arrays.
*
* I have done this by adding to the gr_screen list of function pointers that are set up by the engines init functions.
* I have named the define calls the same name as the original 'bm_' functions so that I havent had to change names all through the code.
*
* Rolled back to an old version of bumpman and made a few changes.
* Added new files: grd3dbumpman.cpp and .h
* Moved the bitmap init function to after the 3D engine is initialised
* Added includes where needed
* Disabled (for now) the D3D8 TGA loading - RT
*
* Revision 2.1.2.2 2002/10/16 00:41:38 randomtiger
* Fixed small bug that was stopping unactive text from displaying greyed out
* Also added ability to run FS2 DX8 in 640x480, however I needed to make a small change to 2d.cpp
* which invloved calling the resolution processing code after initialising the device for D3D only.
* This is because D3D8 for the moment has its own internal launcher.
* Also I added a fair bit of documentation and tidied some stuff up. - RT
*
* Revision 2.1.2.1 2002/10/11 18:50:54 randomtiger
* Checked in fix for 16 bit problem, thanks to Righteous1
* Removed a fair bit of code that was used by the 16 bit code path which no longer exists.
* 32 bit and 16 bit should now work in exactly the same way. - RT
*
* Revision 2.1 2002/08/01 01:41:05 penguin

*
* 9 1/30/99 5:08p Dave
* More new hi-res stuff.Support for nice D3D textures.
*
* 8 1/24/99 11:36p Dave

In the 2d/texture mapper, bitmaps to be drawn will be passed by number.
The 2d function will call a bmpman function to get the bitmap into whatever
format it needs. Then it will render. The only pixels that will ever
get drawn go thru the 2d/texture mapper libraries only. This will make
supporting accelerators and psx easier. Colors will always be set with
the color set functions.
