The series looks good to me.

Regarding patch 4 (the blit-based Tex[Sub]Image change), under what 
circumstances, exactly, is the blit path used?  I'm still trying to 
figure out the code.  Basically, I'm wondering how often we're going 
to hit the blit-based path with the software drivers (llvmpipe in 
particular).  An intermediate texture blit would make things slower 
than just using the regular texstore code, as far as I see it.
