Subject: [PATCH] Revert to r2882 since it awfully broke Castlevania games
 (possibly other games as well). The reasons I replaced GL_GREATER with
 GL_GEQUAL in r2883 are: 1. gbatek says "Hide pixels if Alpha<AlphaRef" 2.
 rasterizer also says "if(shaderOutput.a < gfx3d.alphaTestRef) goto
 rejected_fragment;"
