*   CachedBitmap
*
* Abstract:
*
*   An object to store a bitmap prepared for rendering on a particular
*   Graphics object. The memory storage for the CachedBitmap is opaque
*   to the other Engine code, so the only operations supported are
*   initializing the data (with a bitmap) and using the graphics to
*   draw it on the screen with an integer offset.
*
