Also disables a workaround for "interpolation seams" that I believe to be an old DRI bug. If anyone has skybox (not dome!) seams, try altering the ftc `if 0` to `if 1`.
Less blinding rocket trails is probably the most noticable change, other than a nice speedup in nq timedemos. Little change for overkill, though. Aw...
as the black polygons (duh:) and not as nice looking as the sky dome, but also
not as slow (fps when standing in the normal coridor looking at the sky in
start: 26 for skydome, 37 for id skys, 44 for black). Good for when you want
to see sky other than black but your card can't handle the fillrate
requirements of skydome. I'll clean up the sqrt in there soonish.
The major change is that we no longer require libGL to even exist on the
system at compile time for the GL targets, we dynamicly link to the
libGL of choice at run time. (This probably breaks most non-linux
systems, and all GL targets except -glx, some fixup will be needed.)
(This also kills glquake, dead dead DEAD! GONE FOREVER! WHEE!)
Some gl_draw cleanup.
Commented out equake alias model occlusion test stuff, very experimental.
Added the .lo and .la patterns to the .gitignore files.
Some minor sbar cleanup. (We don't use the disc in use symbol for
anything.)
quakeio.h -> vfile.h
More diff reduction between trunk and my VFS code. Also took the time to
put some headers in order and fix a few #include's pointed out by moving
things around a bit.
