<pre>Commit 547149a9c266496f84ac785d9632e4280405d631 broke the optimization of
clipping away damage below an opaque surface. I think the fix is to track
opaqueness per weston_plane and use that to discard damage, but then track
global opaqueness, that is, accross all planes and use that to clip repainting.
How to reproduce: put simple-egl under the opaque area of weston-terminal,
enable repaint debugging. Observe how simple-egl is repainted.</pre>
