Since we now have the neccessary infrastructure to get notified about changes to the absolute transformation matrix, we can also invalidate the stage-views list on updates to this matrix. So rename absolute_allocation_changed() to absolute_geometry_changed() to make it clear this function is not only about allocations, and call that function recursively for all children on changes to the transformation matrix, too. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1343
