@defmethod[(set-orientation [horizontal? boolean?]) void?]{
  Sets the orientation of the panel, switching it between
  the behavior of the @scheme[vertical-panel%] and that of
  the @scheme[horizontal-panel%].
}

@defmethod[(get-orientation) boolean?]{
  Initially returns @scheme[#t], but if 
  @method[horizontal-panel% set-orientation] is called,
  this method returns whatever the last value passed to it was.
