This adds a public function to get the bounds of the current clipped redraw on a stage. This should only be called while the stage is being painted. The function diverts to a virtual function on the ClutterStageWindow implementation. If the function isn't implemented or it returns FALSE then the entire stage is reported. The clip bounds are in integer pixel coordinates in the stage's coordinate space. http://bugzilla.clutter-project.org/show_bug.cgi?id=2421
