Fix clearing of window background for some transparent notification icons

Browse Source 
This extends the usage of the native clear region call such that its
called also for windows that have parent relative background all the
way up to a native window. That way we get true background relative
background clearing even to a foreign parent, which means that some
transparent notification icons look right again.
