- OpenGL Renderer: Fix bug where translucent fragments drawing on top of zero-alpha fragments were not overwriting the destination fragment color as intended. (Regression from commit 2a1aaf7.)
- OpenGL Renderer: Add true support for the depth-equals test by properly emulating the tolerance value. This fixes many longstanding bugs related to missing polygons, Z-fighting glitches, and other misc. graphical glitches in many games.
