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.
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
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
- some new error checking (and fixes related to that) and cleanup
- fix EFFs not getting released/unloaded properly (was in a local tree but apparently missed CVS)
- minor fixes for bm_release() to produce a more properly cleaned slot
- use fast unloading for page_in stuff since we don't actually want really want the load count changing for texture maps
and to make sure that we free the memory usage regardless of load count
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
always use bm_set_render_target() rather than the gr_ version so that the graphics state is set properly
save the original gamma ramp on OGL init so that it can be restored on exit
add empty gr_opengl_draw_line_list() so that it's not a NULL pointer
make gr_opengl_draw_htl_sphere() just use GLU so we don't need yet another friggin API
