cc: Use occlusion for deciding raster/eviction priorities in browser

The browser compositor should use occlusion to allow lots of
overlapping windows to take up less memory. This reduces our memory
consumption in ash a bit.

Though, the window UI is not considered opaque currently, so more
memory is still used than could be otherwise.
