/** Little wrapper encapsulating an XBitmap
This is to insulate us from changes to the preferred
transport format for bitmaps ( using a sole XBitmap here is
a hack , since it is not guaranteed to work , or to work
without data loss , across different canvases ) . And since
we don ' t want to revert to a VCL Bitmap here , have to wait
until basegfx bitmap tooling is ready .
TODO ( F2 ) : Add support for Canvas - independent bitmaps
here . Then , Slide : : getInitialSlideBitmap and
Slide : : getFinalSlideBitmap must also be adapted ( they no
longer need a Canvas ptr , which is actually a hack now ) .
