Summary CSS animations in filling-forwards state shouldn't force compositing.

<rdar://problem/17923642> Currently CSS animations will force elements to be composited indefinitely, even after the animation is done and we're just filling forwards. We should drop the compositing requirement when we reach the end, which would allow some content to flatten and use less memory.

Comment on attachment 254020 [details] Patch r+, but you need a test that checks that a filling-forward transform animation doesn't make a compositing layer.
