This method late-initializes the canvas helper, providing

|
|
|
it with the necessary device and output objects. Note that
|
|
|
|
|
the CanvasHelper does <em>not</em> take ownership of the
|
|
|
|
|
passed rDevice reference, nor does it perform any
|
|
|
|
|
reference counting. Thus, to prevent the reference counted
|
|
|
|
|
SpriteCanvas object from deletion, the user of this class
|
|
|
|
|
is responsible for holding ref-counted references itself!
