fix for anistotropic filtering messing up with lod bias
be sure that we always reset the properly active texture
get rid of old gamma stuff
loading fix for cubemaps
disable apple_client_storage for now
fix for ATI problem with framebuffers and corrupting starfield bitmaps
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
