-Changed the transform matrix uniform to a 3x4 matrix and packed translation into it to free up uniforms. (3x3 is converted to 3x4 internally, so we were needlessly eating 3*52 extra uniform slots. translationPalette might also have been treated as a vec4 internally too, wasting 52 more slots.)
-matrix3x4 requires opengl2.1 and newer, so added a new featuretable mask.
-Also added a featuretable mask to disable hardware skinning and deferred shading on hardware with less than 1024 vertex uniforms.
NOTE: On old old old amd hardware, evidently a 3x4 matrix might be upgraded to 4x4. I'm unsure, but I doubt such hardware has 1024+ uniform components available to begin with. 4x3 supposedly doesn't do this, but opengl is column-major, so this makes little sense.
-Nametag bubble visbility is oddly inconsistent. May vanish with future planned UI merges...
-VBOs are PAINFULLY slow on ATI hardware. This repos self-compiled davep/shining-fixes branch, so I'll leave the ball in LL's court for now regarding that.
Plus renamed setupViewport to setup[2|3]DViewport.
Migrated mWindowRect to mWindowRectRaw, mVirtualWindowRect to mWindowRectScaled.
Slowly updating getwindow/getworldview calls to new v2 variants as I run across them.
Cleaned up ascent-related code in llmanip.cpp.
Impostor update tweaks.
Edgepatch water occlusion changes. (no patch flickering on edges of screen while moving camera)
Re-structured some shader loading/unloading handling.
These changes are pretty experimental. I'll be holding off of tweaking the paramater managers(among other things) until I know if this stuff is working correctly.
