So, the feature invocation above must be replaced by two calls:

     w.add_subwindow( other_window );
     other_window.move( horizontal_position, vertical_position ); 

Is the old version of ``add_subwindow'' (with three arguments) still
available? If so, this violates the rule that a class has at most one
feature of a given name.  If not, it would seem that in this case the
``obsolete'' facility does nothing for the "early" users of this class.
