    canvases have in them attributes such as TopChild CanvasAbove
    CanvasBelow etc... see NeWS ref. man. for descriptions.

    You could first start by sending a message to all the windows (see
    the All Windows menu code for the root menu) from this list you can
    figure out who is above who etc... using the keys i mentioned above
    for each windows FrameCanvas.
