The current way we keep track of skip-paint children is more difficult than it needs to be, and can lead to subtle bugs. (For one, the skip-paint state of a child is remembered when it is removed then added back again, which is completely unexpected.) Instead of using weak references to track children, just remove items from the skip-paint list by overriding the remove() virtual function of the ClutterContainer interface. The 'skip_paint' hash table is then destroyed in finalize rather than dispose since it doesn't hold references to memory any more but just passively tracks an attribute of the children that are currently in the container. https://bugzilla.gnome.org/show_bug.cgi?id=608848
