Scott's right -- it's the integration of 2D that's causing the problem. I
don't know that "dragging the heels" is actually correct: I know they've
applied some very bright minds to the problem, and made quite a bit of
improvement (this was before 1.2 first came out), but that it was getting
harder and harder to find doable performance wins. I think that if I were to
design it, I'd try to make it so that if you weren't using any of the 2D
features, the overhead that you'd pay would be minimal, and only when you
started turning on matrix transformation or any of the other cool 2D effects
would you have to take a performance hit.
