    Constrain the window to the minimum width for the natural height
    
    GtkWindow now requests the minimum width for the natural height
    of its child, or the opposite; depending on ->get_height_for_width.
    Currently its not done for GTK_WINDOW_POPUP windows as the menushells
    aren't working right yet.
