That's a question of the card supporting it. Some do, some don't.

That's why I'm working on a Bob/Sprite extension that abstracts that.
It will try to use linear blits if possible, or fall back to two-dimensional
ones, if not. It can as well do some kind of garbage collection, as the
individual objects are referenced by an abstract handle.

I can send you a very very preliminary copy for review, if you want.

CU, Andy
