* $Author: bobboau $
*
* Code to actually render stuff using Direct3D
*
* $Log: not supported by cvs2svn $
* Revision 2.44 2004/03/05 09:02:00 Goober5000
* Uber pass at reducing #includes
* --Goober5000
*
* Revision 2.43 2004/02/20 21:45:41 randomtiger
* Removed some uneeded code between NO_DIRECT3D and added gr_zbias call, ogl is set to a stub func.
* Changed -htl param to -nohtl. Fixed some badly named functions to match convention.
* Fixed setup of center_alpha in OGL which was causing crash.
*
* Revision 2.42 2004/02/16 11:47:33 randomtiger
* Removed a lot of files that we dont need anymore.
* Changed htl to be on by default, command now -nohtl
* Changed D3D to use a 2D vertex for 2D operations which should cut down on redundant data having to go though the system.
* Added small change to all -start_mission flag to take you to any mission by filename, very useful for testing.
* Removed old dshow code and took away timerbar compile flag condition since it uses a runtime flag now.
*
* Revision 2.41 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 Gr_bitmap_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 2.40 2003/12/08 22:30:02 randomtiger
* Put render state and other direct D3D calls repetition check back in, provides speed boost.
* Fixed bug that caused fullscreen only crash with DXT textures
* Put dithering back in for tgas and jpgs
*
* Revision 2.39 2003/11/29 17:13:53 randomtiger
* Undid my node fix, it introduced a lot of bugs, update again if you have that version.
*
* Revision 2.38 2003/11/29 10:52:09 randomtiger
* Turned off D3D file mapping, its using too much memory which may be hurting older systems and doesnt seem to be providing much of a speed benifit.
* Added stats command for ingame stats on memory usage.
* Trys to play intro.mve and intro.avi, just to be safe since its not set by table.
* Added fix for fonts wrapping round in non standard hi res modes.
* Changed D3D mipmapping to a good value to suit htl mode.
* Added new fog colour method which makes use of the bitmap, making this htl feature backcompatible again.
*
* Revision 2.37 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 2.36 2003/11/17 04:25:56 bobboau
* made the poly list dynamicly alocated,
* started work on fixing the node model not rendering,
* but most of that got commented out so I wouldn't have to deal with it
* while mucking about with the polylist
*
* Revision 2.35 2003/11/11 02:15:44 Goober5000
* ubercommit - basically spelling and language fixes with some additional
* warnings disabled
* --Goober5000
*
* Revision 2.34 2003/11/06 21:10:26 randomtiger
* Added my batching solution for more efficient d3d_string.
* Its part of the new grd3dbatch module, most of this isnt in use but it might help out later so I've left it in.
*
* Revision 2.33 2003/11/02 05:50:08 bobboau
* modified trails to render with tristrips now rather than with stinky old trifans,
* MUCH faster now, at least one order of magnatude.
*
* Revision 2.32 2003/11/01 21:59:21 bobboau
* new matrix handeling code, and fixed some problems with 3D lit verts,
* several other small fixes
*
* Revision 2.31 2003/10/29 02:09:18 randomtiger
* Updated timerbar code to work properly, also added support for it in OGL.
* In D3D red is general processing (and generic graphics), green is 2D rendering, dark blue is 3D unlit, light blue is HT&L renders and yellow is the presentation of the frame to D3D. OGL is all red for now. Use compile flag TIMERBAR_ON with code lib to activate it.
* Also updated some more D3D device stuff that might get a bit more speed out of some cards.
*
* Revision 2.30 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 2.29 2003/10/26 00:31:58 randomtiger
* Fixed hulls not drawing (with Phreaks advise).
* Put my 32bit PCX loading under PCX_32 compile flag until its working.
* Fixed a bug with res 640x480 I introduced with my non standard mode code.
* Changed JPG and TGA loading command line param to "-t32"
*
* Revision 2.28 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 2.27 2003/10/23 18:03:24 randomtiger
* Bobs changes (take 2)
*
* Revision 2.26 2003/10/17 17:18:42 randomtiger
* Big restructure for D3D and new modules grd3dlight and grd3dsetup
*
* Revision 2.25 2003/10/16 17:36:29 randomtiger
* D3D now has its own gamma system (stored in GammaD3D reg entry) that effects everything.
* Put in Bobs specular fog fix.
*
* Revision 2.24 2003/10/16 00:17:14 randomtiger
* Added incomplete code to allow selection of non-standard modes in D3D (requires new launcher).
* As well as initialised in a different mode, bitmaps are stretched and for these modes
* previously point filtered textures now use linear to keep them smooth.
* I also had to shuffle some of the GR_1024 a bit.
* Put my HT&L flags in ready for my work to sort out some of the render order issues.
* Tided some other stuff up.
*
* Revision 2.23 2003/10/14 17:39:13 randomtiger
* Implemented hardware fog for the HT&L code path.
* It doesnt use the backgrounds anymore but its still an improvement.
* Currently it fogs to a brighter colour than it should because of Bob specular code.
* I will fix this after discussing it with Bob.
*
* Also tided up some D3D stuff, a cmdline variable name and changed a small bit of
* the htl code to use the existing D3D engine instead of work around it.
* And added extra information in version number on bottom left of frontend screen.
*
* Revision 2.22 2003/10/13 05:57:48 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
*
* Revision 2.21 2003/09/25 21:12:24 Kazan
* ##Kazan## FS2NetD Completed! Just needs some thorough bug checking (i don't think there are any serious bugs)
* Also D3D8 Screenshots work now.
*
* Revision 2.20 2003/09/23 02:42:53 Kazan
* ##KAZAN## - FS2NetD Support! (FS2 Open PXO) -- Game Server Listing, and mission validation completed - stats storing to come - needs fs2open_pxo.cfg file [VP-able]
*
* Revision 2.19 2003/09/14 19:01:35 wmcoolmon
* Changed "cell" to "Cmdline_cell" -C
*
* Revision 2.18 2003/09/07 18:14:53 randomtiger
* Checked in new speech code and calls from relevent modules to make it play.
* Should all work now if setup properly with version 2.4 of the launcher.
* FS2_SPEECH can be used to make the speech code compile if you have SAPI 5.1 SDK installed.
* Otherwise the compile flag should not be set and it should all compile OK.
*
* - RT
*
* Revision 2.17 2003/08/31 06:00:41 bobboau
* an asortment of bugfixes, mostly with the specular code,
* HUD flickering should be completly gone now
*
* Revision 2.16 2003/08/22 07:35:08 bobboau
* specular code should be bugless now,
* cell shadeing has been added activated via the comand line '-cell',
* 3D shockwave models, and a transparency method I'm calling edge and center alpha that could be usefull for other things, ask for details
*
* Revision 2.15 2003/08/16 03:52:23 bobboau
* update for the specmapping code includeing
* suport for seperate specular levels on lights and
* optional strings for the stars table
* code has been made more organised,
* though there seems to be a bug in the state selecting code
* resulting in the HUD being rendered incorectly
* and specmapping failing ocasionaly
*
* Revision 2.14 2003/08/12 03:18:33 bobboau
* Specular 'shine' mapping;
* useing a phong lighting model I have made specular highlights
* that are mapped to the model,
* rendering them is still slow, but they look real purdy
*
* also 4 new (untested) comand lines, the XX is a floating point value
* -spec_exp XX
* the n value, you can set this from 0 to 200 (actualy more than that, but this is the recomended range), it will make the highlights bigger or smaller, defalt is 16.0 so start playing around there
* -spec_point XX
* -spec_static XX
* -spec_tube XX
* these are factors for the three diferent types of lights that FS uses, defalt is 1.0,
* static is the local stars,
* point is weapons/explosions/warp in/outs,
* tube is beam weapons,
* for thouse of you who think any of these lights are too bright you can configure them you're self for personal satisfaction
*
* Revision 2.13 2003/08/05 23:45:18 bobboau
* glow maps, for some reason they wern't in here, they should be now,
* also there is some debug code for changeing the FOV in game,
* and I have some changes to the init code to try and get a 32 or 24 bit back buffer
* if posable, this may cause problems for people
* the changes were all marked and if needed can be undone
*
* Revision 2.12 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 2.11 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 2.10 2003/03/02 05:43:48 penguin
* ANSI C++ - fixed non-compliant casts to unsigned short and unsigned char
* - penguin
*
* Revision 2.9 2003/02/16 05:14:28 bobboau

* more importantly I (think I) have fixed all major bugs with fighter beams, and added a bit of new functionality
*
* Revision 2.8 2003/01/20 05:40:49 bobboau
* added several sExps for turning glow points and glow maps on and off
*
* Revision 2.7 2003/01/19 01:07:41 bobboau
* redid the way glowmaps are handeled, you now must set the global int GLOWMAP (no longer an array) before you render a poly that uses a glow map then set GLOWMAP to -1 when you're done with, fixed a few other misc bugs it
*
* Revision 2.6 2003/01/09 21:20:21 phreak
* fixed a small error in bob's code
*
* Revision 2.5 2003/01/05 23:41:50 bobboau

* and... oh ya, added glow mapping
*
* Revision 2.4 2002/10/05 16:46:09 randomtiger
* Added us fs2_open people to the credits. Worth looking at just for that.
* Added timer bar code, by default its not compiled in.
* Use TIMEBAR_ACTIVE in project and dependancy code settings to activate.
* Added the new timebar files with the new code.
*
* Revision 2.3.2.22 2002/11/16 20:09:54 randomtiger

*
* Revision 2.3.2.21 2002/11/11 21:26:04 randomtiger
*
* Tided up D3DX8 calls, did some documentation and add new file: grd3dcalls.cpp. - RT
*
* Revision 2.3.2.20 2002/11/10 11:32:29 randomtiger
*
* Made D3D8 mipmapping optional on command line flag -d3dmipmip, off by default.
* When on is now less blury. - RT
*
* Revision 2.3.2.19 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 2.3.2.18 2002/11/05 10:27:39 randomtiger
*
* Fixed windowed mode bug I introduced.
* Added Antialiasing functionality, can only be sure it works on GF4 in 1024 mode. - RT
*
* Revision 2.3.2.17 2002/11/02 13:54:26 randomtiger
*
* Made a few cunning alterations to get rid of that alpha bug but might have a slight slowdown.
* Non alpha textures are now alpha textures with (if texture format supported) just one bit for alpha.
* And non alpha blending is now alpha blending with automatic disregaring of 0 alpha.
*
* Revision 2.3.2.16 2002/10/31 15:17:09 randomtiger
*
* Added mipmapping, should have done that ages ago! - RT
*
* Revision 2.3.2.15 2002/10/26 01:24:22 randomtiger

* Fixed tga bug. - RT
*
* Revision 2.3.2.14 2002/10/21 16:33:41 randomtiger
* Added D3D only 32 bit TGA functionality. Will load a texture as big as your graphics card allows. Code not finished yet and will forge the beginnings of the new texture system. - RT
*
* Revision 2.3.2.13 2002/10/20 22:21:48 randomtiger
* Some incomplete code to handle background drawing when message boxes are drawn.
* It doesnt work but its a good base for someone to start from. - RT
*
* Revision 2.3.2.12 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 2.3.2.11 2002/10/14 21:52:02 randomtiger
* Finally tracked down and killed off that 8 bit alpha bug.
* So the font, HUD and 8 bit ani's now work fine. - RT
*
* Revision 2.3.2.10 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 2.3.2.9 2002/10/08 14:33:27 randomtiger
* OK, I've fixed the z-buffer problem.
* However I have abandoned using w-buffer for now because of problems.
* I think I know how to solve it but Im not sure it would make much difference given the way FS2 engine works.
* I have left code in there of use if anyone wants to turn their hand to it. However for now
* we just need to crack of the alpha problem then we will have FS2 fully wokring in DX8 on GF4 in 32 bit.
*
* Revision 2.3.2.8 2002/10/04 00:48:42 randomtiger
* Fixed video memory leaks
* Added code to cope with lost device, not tested
* Got rid of some DX5 stuff we definately dont need
* Moved some enum's into internal,h because gr_d3d_set_state should be able to be called from any dx file
* Cleaned up some stuff - RT
*
* Revision 2.3.2.7 2002/10/02 17:52:32 randomtiger
* Fixed blue lighting bug.
* Put filtering flag set back in that I accidentally removed
* Added some new functionality to my debuging system - RT
*
* Revision 2.3.2.6 2002/10/02 11:40:19 randomtiger
* Bmpmap has been reverted to an old non d3d8 version.
* All d3d8 code is now in the proper place.
* PCX code is now working to an extent. Problems with alpha though.
* Ani's work slowly with alpha problems.
* Also I have done a bit of tidying - RT
*
* Revision 2.3.2.5 2002/09/28 22:13:43 randomtiger
* Sorted out some bits and pieces. The background nebula blends now which is nice. � RT
*
* Revision 2.3.2.4 2002/09/28 12:20:32 randomtiger
* Just a tiny code change that lets stuff work in 16 bit.
* For some reason 16 bit code was taking a different code path for displaying textures.
* So until I unstand why, Im cutting off that codepath because it isnt easy to convert into DX8.
*
* Revision 2.3.2.3 2002/09/28 00:18:08 randomtiger
* Did some work on trying to get textures to load from pcx, define TX_ATTEMPT for access to it.
* Converted some DX7 blending calls to DX8 which a fair difference to ingame visuals.
*
* - RT
*
* Revision 2.3.2.2 2002/09/24 18:56:42 randomtiger
* DX8 branch commit
*
* This is the scub of UP's previous code with the more up to date RT code.

* Took out redundant code for font bitmap offsets that converted to a
* float, then later on converted back to an integer. Quite unnecessary.
*
* 53 5/24/98 6:45p John
* let direct3d do all clipping.
*
* 52 5/24/98 3:42p John
* Let Direct3D do clipping on any linear textures, like lasers.
*
* 51 5/23/98 7:18p John
* optimized the uv bashing a bit.
*
* 50 5/22/98 1:11p John
* Added code to actually detect which offset a line needs
*
* 49 5/22/98 12:54p John

* lines draw on all cards.
*
* 48 5/22/98 9:00a John
* Fixed problem of no fading out of additive textures due to Permedia2
* fix. Did this by dimming out the vertex RGB values.
*
* 47 5/21/98 9:56p John
* Made Direct3D work with classic alpha-blending only devices, like the
* Virge. Added a texture type XPARENT that fills the alpha in in the
* bitmap for Virge. Added support for Permedia by making making
* additive alphablending be one/one instead of alpha/one, which didn't
* work, and there is no way to tell this from caps.
*
* 46 5/20/98 9:45p John
* added code so the places in code that change half the palette don't
* have to clear the screen.
*
* 45 5/20/98 3:10p John
* Made lines work even if no alphagouraud capabilities on the card.
*
* 44 5/19/98 4:50p Lawrance
* JAS: Fixed some bugs on Alan's nVidia Riva128 PCI where some
* unitiallized fields, namely vertex->shw were causing glitches.

* 43 5/19/98 1:46p John
* Fixed Rendition/Riva128 uv problems.
*
* 42 5/19/98 12:34p John
* added code to fix uv's on rendition. added code to fix zbuffering
* problem on rendition.
*
* 41 5/18/98 8:26p John
* Made scanline be line. Made lines work if no line alpha blending
* supported. Made no alpha mode use alpha off.
*
* 40 5/17/98 4:13p John
* Made zbuffer clear only clear current clip region
*
* 39 5/17/98 3:23p John
* Took out capibility check for additive blending. Made gr_bitmap_ex
* clip properly in glide and direct3d.
*
* 38 5/15/98 8:48a John
* Fixed bug where one-pixel line was getting left on right and bottom.
*
* 37 5/12/98 8:43p John
* fixed particle zbuffering.
*
* 36 5/12/98 10:34a John
* Added d3d_shade functionality. Added d3d_flush function, since the
* shader seems to get reorganzed behind the overlay text stuff!
*
* 35 5/12/98 10:06a John
* Made all tmaps "clamp-clip". This fixed bug with offscreen hud
* indicators not rendering.
*
* 34 5/12/98 8:18a John
* Put in code to use a different texture format for alpha textures and
* normal textures. Turned off filtering for aabitmaps. Took out
* destblend=invsrccolor alpha mode that doesn't work on riva128.
*
* 33 5/11/98 10:58a John
* Fixed pilot name cursor bug. Started adding in code for alphachannel
* textures.
*
* 32 5/09/98 12:37p John
* More texture caching
*
* 31 5/09/98 12:16p John
* Even better texture caching.
*
* 30 5/08/98 10:12a John
* took out an mprintf
*
* 29 5/07/98 11:31a John
* Removed DEMO defines
*
* 28 5/07/98 10:28a John
* Made texture format use 4444. Made fonts use alpha to render.
*
* 27 5/07/98 10:09a John
* Fixed some bugs with short lines in D3D.
*
* 26 5/07/98 9:54a John
* Added in palette flash functionallity.
*
* 25 5/07/98 9:40a John
* Fixed some bitmap transparency issues with Direct3D.
*
* 24 5/06/98 11:21p John
* Fixed a bitmap bug with Direct3D. Started adding new caching code into
* D3D.
*
* 23 5/06/98 8:41p John
* Fixed some font clipping bugs. Moved texture handle set code for d3d
* into the texture module.
*
* 22 5/06/98 8:07p John
* made d3d clear work correctly.
*
* 21 5/06/98 8:00p John
* Got stars working under D3D.
*
* 20 5/06/98 5:30p John

*
* 17 5/03/98 10:52a John
* Made D3D sort of work on 3dfx.
*
* 16 5/03/98 10:43a John
* Working on Direct3D.
*
* 15 4/14/98 12:15p John
* Made 16-bpp movies work.
*
* 14 4/10/98 5:20p John
* Changed RGB in lighting structure to be ubytes. Removed old
* not-necessary 24 bpp software stuff.
*
* 13 4/09/98 11:05a John
* Removed all traces of Direct3D out of the demo version of Freespace and
* the launcher.
*
* 12 3/12/98 5:36p John
* Took out any unused shaders. Made shader code take rgbc instead of
* matrix and vector since noone used it like a matrix and it would have
* been impossible to do in hardware. Made Glide implement a basic
* shader for online help.
*
* 11 3/11/98 1:55p John
* Fixed warnings
*
* 10 3/10/98 4:18p John
