I don't believe this is something that should be in SDL. I understand
the need for it, but one of the key ideas in SDL is that SDL doesn't do
a lot of graphics, it makes it easy to use existing graphics libraries
to do graphics. I like the idea of having scaled and rotated blits in
SDL because they complete the 2D support that is already there.
