  69         The Canvas object combines the actual Window canvas with
  70         the XGraphicDevice interface. This is because there's a
  71         one-to-one relation between them, anyway, since each window
  72         can have exactly one canvas and one associated
  73         XGraphicDevice. And to avoid messing around with circular
  74         references, this is implemented as one single object.
