Detailed Description

Product of this component's factory.

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