As there are now a lot of branches to cover, I'm going to concentrate on the `SkinningControl` one, which *seems* to be the current state of the art. I haven't at this stage investigated how `AssetManager.loadModel(String)` determines which classes to instantiate when loading a model, but I'm going to assume that I can coerce my models to be loaded in a non-deprecated form.
