The current structure of this code is so hateful I can't bring myself to
say anything about whether changing the current code is good or bad.

I have a dream that one call would try to make a surface
(miptree/region) out of the PBO, then we'd see about whether it matches
up nicely and zero-copy/blit using that.  That would be reusable for
texsubimage, which is currently awful in this respect.
