    Bug 732072: Image windows created by script-fu plug-ins...
    
    are opened behind the previously focused Image Window
    
    libgimp/gimpui.c bypasses gtk in setting the transient_for
    property and so it is not possible to call
    gtk_set_transient_for (dialog, NULL), but it is necessary
    to go directly to the gdk level.
