Both X and Y offsets work on sky textures now. Old incorrect offset has been removed, so old skies lined up with the horizon special should be set to +16 Y offset.
Two reasons:
- Makes it more straight-forward to add brightmaps to the non-power-of-two rendering functions.
- Made it easier to split off brightmap rendering. Hopefully improves performance, but I haven't thoroughly tested this.
Fix some R_MapPlane crashes in splitscreen; debugrender_visplanes and debugrender_portal; some multithreading crashes
Closes#1032 and #1021

debugrender_contrast -1.0 to 1.0, default 0.0 (no change).
Higher values add more contrast (darkens the level), lower
values add less (brighten). Does not affect thing drawing.
Software mode only.
Adds r_debug.cpp
