  39             This method late-initializes the canvas helper, providing
  40             it with the necessary device and output objects. Note that
  41             the CanvasHelper does <em>not</em> take ownership of the
  42             passed rDevice reference, nor does it perform any
  43             reference counting. Thus, to prevent the reference counted
  44             SpriteCanvas object from deletion, the user of this class
  45             is responsible for holding ref-counted references itself!
