     11 *   CachedBitmap is a representation of an accelerated drawing
     12 *   that has restrictions on what operations are allowed in order
     13 *   to accelerate the drawing to the destination.

     26 * Abstract:
     27 *
     28 *   An object to store a bitmap prepared for rendering on a particular
     29 *   Graphics object. The memory storage for the CachedBitmap is opaque
     30 *   to the other Engine code, so the only operations supported are
     31 *   initializing the data (with a bitmap) and using the graphics to
     32 *   draw it on the screen with an integer offset.
     33 *
     34 *   Look for the class definition in GdiplusHeaders.h
