Compositor: sync stacking of window actors even if they're not parented to the window groups

Browse Source 
Window actors might be temporarily parented to intermediate actors during
effect, but we should not require that the plugin keeps track of stacking.
Rather, assume that the intermediate groups holds a whole stack, and
applying position within it.
