Michael Natterer f4af9b549e Globally switch to saying "window_id" instead of just "window" 
when dealing with native window handles. Also get rid of using
GdkNativeWindow and simply consistently use guint32 all over the
place. This is more obvious and consistent and keeps the diff to the
gtk3-port branch smaller.
