Am I missing something -- isn't this setting the appropriate blend
modes? Is the constant color not getting updated correctly?
Yes, exactly, the constant color isn't updated at all (so the color is
_really_ constant ;-)). Mesa would call ctx-Driver.BlendColor to inform
the driver of the

ok, I'll try to implement it. This register is just before the

the GL_EXT_blend_xx_separate extensions) at the same time. Unfortunately
requires a drm change, and unfortunately

As far as I can see though this would get very ugly, with lots of if

values in ABLENDCNTL alone then it would be no problem at all). Maybe
