cc: Preserve partial culling from child compositor.
When the child compositor performs occlusion culling and determines
what part of the quad is visible, we should preserve this in the
browser compositor, and only shrink the visible (unoccluded) rect on
quads if we're able due to occlusion in the browser. We should not
grow the visible rect ever.
Tests:
QuadCullerTest.PartialCullingNotDestroyed
QuadCullerTest.PartialCullingWithOcclusionNotDestroyed
