We have cases where we have opaque surfaces occluding other opaque surfaces in SwCompositor that cause us to blit large areas of pixels that will never be seen, such as when content occludes the browser chrome background. Doing even a coarse occlusion/clipping of these surfaces can save us a lot of blitting work.
