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).
