biosuits, pents, and quads wear off are now gone. Sort of. They are
caused by places where two texture edges meet and there are little gaps
at the seams where nothing gets drawn. This is also why noclip screws w/
the screen if you walk outside of the map in the GL targets. We now draw
a backdrop whose color is set by r_clearcolor, ala software renderer.
common_quakedef.h (and thus all files)
This solves a build break when the OpenGL includes are not in /usr/include,
since the OpenGL include path is only used when compiling files that use
OpenGL.
like adding a gratuitious feature, GL target users can crosshair 3 for a
completely new crosshair and higher resolution crosshair (oooh!) Software
renderer doesn't have it because...well look at Draw_Crosshair() in
draw.c, it's truly a nightmare! You have to plot each pixel individually,
makes you feel like you're coding in Applesoft BASIC. If you want it,
figure out how to do it sanely.
