I should not write emails directly after getting up... READTEX was what I
What I am also wondering about this patch: Its general wisdom that texture
load + draw a quad is faster than glDrawPixels, although glDrawPixels is the
more natural match to framebuffer locking. Why aren't drivers implementing
glDrawPixels with texture+draw in that case? Or does glDrawPixels do anything
we don't need that slows it down compared to the texture codepath?
