It's mostly a matter of getting rid of set_shader() / unset_shader()
and introducing calls for doing color and depth blits. This shouldn't
be much of a surprise, I'm pretty sure we looked at this when Roderick
was still working on the blit code.

That's not necessarily something that belongs in individual blitters
either. The idea is to make the blitters do GPU -> GPU transfers only,
and do CPU <-> GPU mostly as uploads / downloads. I have some patches
that go in that direction already.
