[Xorg-driver-geode] Glyph rendering

[Huang, FrankR]

If that is so, it is easy to handle.
But actually from my debug, it is
Src:PICT_a8r8g8b8, Mask:0, Dest: PICT_a8.
Can we do that directly and drop R,G,B of source?

Thanks,
Frank

Okay, this is really really easy to do - it's a saturating addition:

d = MIN(s + d, 255);

That should solve your immediate problem.
