    Added set_transient_for() implementation for GdkOffscreenWindow
    
    Just a noop that is better than crashing in the case this is called
    (it can be called for a toplevel GtkWindow that is parented into
    another widget by setting gtk_widget_set_parent_window to an offscreen
    window).
