Derek Sollenberger 2d14213849 Initial implmentation of AnimatedImageDrawables on the RenderThread.
The current implementation schedules the next frame of the images
to be decoded after the current frame completes but potentially
schedules tasks that will result in a no-op execution if a new
frame is not yet needed.

Test: HwAccelerationTest
