* Composition would help activity switching and the frame animation a lot. We cannot turn it on for all the windows for memory reason but it might be reasonable to composite the current active activity and the frame. It has a cost anyway, so we should see if we can improve drawing efficiency instead. | * Composition would help activity switching and the frame animation a lot.
