+Subject: [PATCH] MetaWindowGroup: fix paint volume
+
+In the past, MetaWindowGroup was allocated the size of the screen and
+painted the size of the screen because it contained the screen background,
+but now we also have the "top window group" which contains only popup
+windows, so the allocation doesn't properly reflect the paint bounds
+of the window group. Compute the paint bounds accurately from the
+children.
