cc: Split animating and drawing into separate actions
Split impl-side animating and drawing into separate actions. This is
needed to allow for the possibility of a commit between animating and
drawing so that the main thread gets a chance to consume the new
animation state. In particular this allows the main thread to
synchronize with a fling animation using an onscroll handler.
