- Software* + OpenGL support
- *Not supported: R_DrawColumnShadowed_8
- This has something to do with walls and FOF lights.
However, I don't see an easy code solution and I don't
know how to even test this.
- Cache DBGLINE texture
- Draw this texture at horizon (player's eye level)
- Draw this texture at max brightness
- Do not slope skew this texture
- Use R_DrawColumn_Flat_8 to colorize the this texture
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
