Animations in accelerated compositing on Windows currently use AnimationController to do the animation in software. We should switch to using CACFAnimation to offload this work to Core Animation. This will be particularly useful when bug 39496 is fixed, as then the animations will happen off the main thread. But it could be useful even before then.
