> GraphicsLayer should not do any loading. If you are going to kick off resource loads, you should do that in a similar way to how we load images for style, or something.

I think we should teach RenderLayer::updateOrRemoveFilterClients about the animations. It should iterate on the "-webkit-filter" property keyframes and add the clients as needed. I suppose you would need to slightly change RenderLayerFilterInfo::updateCustomFilterClients to do that. This way the shaders are going to be loaded ahead of time, even if the animation is not running in the compositor.

AnimationController should be able to tell what are the animations running on a RenderObject and iterate on the keyframes of a specific property.
