Double the performance of animations.

There is a hard-coded limit to the frame rate of animations; this commit increases that rate by changing the inter-frame delay from 30 ms to 10 ms (although the actual delay will be determined by the maximum refresh rate of the system and the system load). For example, the effective maximum on current devices is 55 fps, or a delay of about 16 ms.
