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
- remove special uv offsets for non-standard res, they were stupid anyway and don't actually fix the problem (which should actually be fixed now)
- avoid some costly math where possible in the drawing functions
- add opengl_error_string(), this is part of a later update but there wasn't a reason to not go ahead and commit this peice now
- minor cleanup to Win32 extension defines
- make opengl_lights[] allocate only when using OGL
- cleanup some costly per-frame lighting stuff
- clamp textures for interface and aabitmap (font) graphics since they shouldn't normally repeat anyway (the default)
(doing this for D3D, if it doesn't already, may fix the blue-lines problem since a similar issue was seen with OGL)
use nicest hints for texture compression, should improve quality a little
when reporting compressed sizes to debug log make ani size be total, not per frame
better support for mipmaps and mipmap filtering
add reg option "TextureFilter" to set bilinear or trilinear filter
clean up bitmap_id/bitmap_handle/texture_handle madness that made things difficult to understand
small fix for using 24-bit images on 16-bit bpp visual (untested)
- minor cleanup of things that have bothered me at one time or another
- slight speedup from state switching
- slightly better specmap handling, fixes a couple of (not frequent) strange and sorta random issues
- make sure to only disable HTL arb stuff when in HTL mode
- handle any extra lighting pass before spec pass so the light can be applied properly
make debug messages a bit more readable
clean up the debug console commands for minimize and anisotropic filter setting
make anisotropic filter actually work correctly and have it settable with a reg option
give opengl_set_arb() the ability to disable all features on all arbs at once so I don't have to everywhere
add -img2dds support
cleanup some D3D stuff (missing a lot since the old code is so unstable I couldn't get it working like I wanted)
some minor OGL cleanup and small performance changes
converge the various pcx_read_bitmap* functions into one
cleanup/rename/remove some cmdline options
fix OGL fullscreen switch for SDL since the old way only worked under Linux and not OSX or Windows
fix OGL version check, it would allow a required major version to be higher if the required minor version was lower than current
speed up gr_opengl_flip() just a tad
inverted gamma slider fix that Sticks made to D3D
possible fix for ATI green screens
move opengl_check_for_errors() out of gropentnl so we can use it everywhere
fix logged OGL info from debug builds to be a little more readable
if an extension is found but required function is not then fail
try to optimize glDrawRangeElements so we are not rendering more than the card is optimized for
some 2d matrix usage checks
optimize opengl_create_texture_sub() by not doing any extra image processing if we don't have to
if an image is already power-of-2 or we don't need power-of-2 then avoid the extra time and memory usage
- remove all bitmap section support and fix problems with previous attempt

- use CLAMP() define in gropengl.h for gropengllight instead of single clamp() function
- remove some old/outdated code from gropengl.cpp and gropengltexture.cpp
add lab stuff to Makefile
build unbreakage for everything that's not MSVC++ 6
lots of warning fixes
fix OpenGL rendering problem with ship insignias
no Warnings() in non-debug mode for Linux (like Windows)
some campaign savefile fixage to stop reverting everyones data
fix VBO crash with multitexture using same uv coord data
little speedup of opengl_tcache_frame()
error message to make sure hardware supports the minimum texture size
move OpenGL version check out of the extention printout code
disable 2d_poof with OpenGL
