Tricky. In theory I guess an overlay (like used for the terminal drag overlay and in the gtk3 version the recreated visual flash) could be used. I suspect the performance might be a problem though. It's not obvious what additional impact drawing transparent overlays every refresh/draw call would cause.

Your suggestion in the bugzilla about an API settable global dimming value would be much better, if it was accepted.
