    """
    A vertically scrolled Frame that can be treated like any other Frame
    ie it needs a master and layout and it can be a master.
    :width:, :height:, :bg: are passed to the underlying Canvas
    :bg: and all other keyword arguments are passed to the inner Frame
    note that a widget layed out in this frame will have a self.master 3 layers deep,
    (outer Frame, Canvas, inner Frame) so 
    if you subclass this there is no built in way for the children to access it.
    You need to provide the controller separately.
