    HACK: Allow GtkLayout to have children dragged into it at mouse position.
    
    This is a hack and all GTK_IS_FIXED() GTK_IS_LAYOUT() statements
    in GladeDesignView code needs to go away.
    
    This should instead be properly handled by a general feature of
    GladeWidget/GladeWidgetAdaptor.
