------- Additional Comments from vollick at chromium.org
There's no more copying back to the LayerChromiums. This patch just ensures we
don't skip subtrees due to opacity when opacity is animating.

I have also removed the code that bails when animation delay is set, since we
get that for free. I have also updated
CCLayerAnimationController::removeCompletedAnimations so that it does not
attempt to destroy animations on the wrong thread.

I will be writing another patch which will tick animations on the main thread
as well to supply better information to the culler, but this is a larger
change.
