            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).
