get rid of the default combine texture state, we don't need it in general, and it can screw up fonts
get rid of the secondary color support, it doesn't do much in non-HTL mode, screws up various things, and has long since been obsolete but material setup
get rid of the old gamma setup, it actually conflicts with newer gamma support
default texture wrapping to edge clamp
do second gr_clear() on init to be sure and catch double-buffer
make sure that our active texture will always get reset to 0, rather than leaving it at whatever was used last
fixed that damn FBO bug from it hanging on textures and causing some rendering errors for various people
only lock verts once in HTL model rendering
remove two old/unused MR flags (MR_ALWAYS_REDRAW, used for caching that doesn't work; MR_SHOW_DAMAGE, didn't do anything)
add MR_FULL_DETAIL to render an object regardless of render/detail box setting
change "model_current_LOD" to a global "Interp_detail_level" and the static "Interp_detail_level" to "Interp_detail_level_locked", a bit more descriptive
minor bits of cleanup
change a couple of vm_vec_scale_add2() calls to just vm_vec_add2() calls in ship.cpp, since that was the final result anyway
clean up view/proj matrix fubar that made us need far more matrix levels that actually needed (partial fix for Mantis #563)
add debug safety check to make sure that we don't use more than 2 proj matrices (all that GL is required to support)
set up a texture matrix for the env map to that it doesn't move/look funky
various lighting code cleanups
- try to always make sure beam origin lights occur outside of model
- make Static_lights[] dynamic
- be sure to reset to first 8 lights when moving on to render spec related texture passes
- add ambient color to point lights (helps warp effects)
- sort lights to try and get more important and/or visible lights to always happen in initial render pass
- go back to using minimize mode which non-active, but doin't minimize when Fred_running
- remove temporary cmdline options (-spec_scale, -env_scale, -alpha_alpha_blend)
- change FBO renderbuffer link around a little to maybe avoid freaky drivers (or freaky code)
minor cleanup of old code and default settings
try not to bother with depth test unless we are actually going to need it (small performance boost in some cases)
don't clear depth bit in flip(), while technically correct it's also a bit redundant (and comes with a slight performance hit)
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
- 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)
let gr_render_buffer() render untextured polys (OGL only until some D3D people fix it on their side)
add MR_SHOW_OUTLINE_HTL flag so we easily render using HTL mode for wireframe views
make Interp_verts/Interp_norms/etc. dynamic and get rid of the extra htl_* versions
- 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
minor cleanup and readability changes
get Apple GL version change in CVS finally, the capabilities of an Apple GL version don't neccessarily correspond to it's features
