  81         The Canvas object combines the actual Window canvas with
  82         the XGraphicDevice interface. This is because there's a
  83         one-to-one relation between them, anyway, since each window
  84         can have exactly one canvas and one associated
  85         XGraphicDevice. And to avoid messing around with circular
  86         references, this is implemented as one single object.
