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.
