part of SAL, we might change that).

This method late-initializes the bitmap canvas helper,

providing it with the necessary device and output

objects. The internally stored bitmap representation is

updated from the given bitmap, including any size
|

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