  47
  48             This is to insulate us from changes to the preferred
  49             transport format for bitmaps (using a sole XBitmap here is
  50             a hack, since it is not guaranteed to work, or to work
  51             without data loss, across different canvases). And since
  52             we don't want to revert to a VCL Bitmap here, have to wait
  53             until basegfx bitmap tooling is ready.

  55             TODO(F2): Add support for Canvas-independent bitmaps
  56             here. Then, Slide::getInitialSlideBitmap and
  57             Slide::getFinalSlideBitmap must also be adapted (they no
  58             longer need a Canvas ptr, which is actually a hack now).
