------- Additional Comments from James Robinson <jamesr at chromium.org>
We discussed the placement of the visibility checks and it seems like since it
depends on composited bounds doing it in RenderLayerCompositor and querying the
result later is the right thing to do.	I think we could tweak exactly how that
state is maintained and carried forward, but this seems like a good start.
