I don't remember. It may have been with D3D. I just now removed the
x/y<0 clip and basic drawing appeared to work in OpenGL. I'll play
around with it more later.
There is this:
/* Note:
* Drivers are guaranteed that the parent is not a subbitmap itself
* and that the passed rectangle lies fully within the parent.
*/
which would no longer be true. If for some reason it's problematic
with some drivers, I don't mind if they return NULL. I think that's
more useful than the odd cropping that currently takes place.
