I guess we need some of these.

Most of these tests seem to dump layers in response to an animationStart event, and that timing changes with this patch. The tests look OK when run manually; I think we'll just create the layers later.

[Simon Fraser (smfr)]

This patch breaks accelerated animations, because we don't do a compositing update after the animation starts (AnimationState New -> StartWaitTimer), so end up running the animation in software.

[Simon Fraser (smfr)]

We need to have already created the composing layer before:

[Simon Fraser (smfr)]

This is a delicate dance about doing compositing updates at the right time. We have to do a compositing update when the animation is in StartWaitStyleAvailable, not before!

[Simon Fraser (smfr)]

This patch sequence tidies up the legacy animation code path so that only animation changes that start/stop accelerated animations trigger recompositeLayer.

The Web Animations code path is fixed by the first patch.

Are there any clients left for invalidateStyleAndLayerComposition after this? Can we remove the whole concept?

[Simon Fraser (smfr)]

Yes, there are clients: things related to composited iframes, plugins etc.
