Bitmap is specifically array of integers. So it does not make sense to traverse it as a complex structure considering that all its items are real objects. it could be quite expensive. Bitmap represents an image (form) and I think it is logical to trait it as a whole structure, like bytearray or string. And EmptyObjectTravelGuide marks such kind of objects to be not traversable. So the issue was with missing implementation of Bitmap serialization. TostSerializer requires that any integral object implements couple of "primitive methods". And it was not done for Bitmap. I fixed serializer and released all dependent projects.
