the background. This is achieved by doing only a (qf)glFlush at the end of
the frame, doing the inter rendering-frame processing (ie, client frame
processing), glFinish, glXSwapBuffers, then starting the next frame. I've
changed the glFinish call in SCR_UpdateScreen to glFlush and the glFlush
call in GL_EndRendering to glFinish because there's no point in calling
glFinish followed by glFlush. Also, SwapBuffers should always be precedded
by glFinish rather than just glFlush (in Lordhavoc's experience). The
GL_EndRendering at the end of SCR_UpdateScreen got moved to the beginning.
Less blinding rocket trails is probably the most noticable change, other than a nice speedup in nq timedemos. Little change for overkill, though. Aw...
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.
