TODO:
- Translating bone data the right way, at least so it looks OK in our viewer.
- Animations, data looks like an encoded bitsteam starting with some decoder state which does reoccur so now and then in larger files. The type of encoding used is still unknown but it's guessed that it's some kind of delta encoding.
- Fix rendering of Dinosaur Hunter 1996 E3 models.
