[Mesa-dev] [PATCH 2/2] meta: Handle bitmaps with alpha test enabled.

Unless a fragment shader is active (very rare), all the fragments
emitted for a bitmap should have the same RGBA color. So the only two
possible outcomes of applying the alpha test to glBitmap is either the
bitmap is drawn normally (as if alpha test is disabled) or nothing is
drawn at all. I think we could test for this and either no-op the
glBitmap or draw the bitmap with the current code as-is.
What do you think?
