+            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).
