cc: Apply occlusion before creating quads in UIResourceLayerImpl.
This makes the AppendQuads method query occlusion directly and subtract
it from the quads it would create before they are created, skipping
quads that are completely occluded and avoiding a malloc/free for them.
Depends on: https://codereview.chromium.org/201153021/
