add chksum support for VPs, both a startup in debug builds, and via cmdline option (-verify_vps)
little cleanup in cmdline.cpp (get rid of the remaining "fix bugs" crap)
add back the "-32bit" option, for retail compatibility (doesn't do anything, it's just there to avoid the unknown option message)
add "-debug_window" to turn on the Windows-only extra debug output window (it's off by default now, only logging to file instead)
fix bug where white space chars didn't get dropped from the end of a option string like they were supposed to
allow for something like "-ambient_factor 100 -ambient_factor 70" to use the proper value, the last one specified, rather than just accept the first instance
make CTRL-SHIFT-S hotkey work in mission simulator (it's a toggle, so you can turn it on or off while on the screen)
fix a bug where blank lines would show up in the campaign list for branch/alternate type missions that are otherwise marked as not completed
- comment out that -fixbugs and -nocrash crap, that's just stupid
- move -env off of the experimental list (since it's working pretty well in OGL)
- remove -nobeampierce
- remove -max_subdivide (didn't do anything)
- remove -rt (didn't do anything, and per-coder cmdline options should never be in CVS)
- move -cache_bitmaps to game speed rather than graphics
- add options for env and spec map scaling for envmaps (temporary, to be removed before official 3.6.8)
- add option for new alpha blend mode so that artists can still test with it but not mess up normal users with the bad MediaVPs
- remove -d3d_particle (it's obsolete now)
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
