## Discussion

\discussion This may be used to request where within the destination buffer the display updates should be placed. Use
CGRectCreateDictionaryRepresentation to convert from a CGRect to the value used here.   Note: The coordinate system for
the destination rectangle is always specified in output pixels to match the fact that the output buffer size is also
specified in terms of pixels.
