Changes to the Model API - IModelState now works with Optional. Handling of parts of the model is not optional, and coordinate space/result interpretation is up to the caller. IModel doesn't extend IModelPart by default anymore; MapModelState uses composition to achieve previous functionality, IModelPart implementations are disjoint now. Updated perspective handing to the new API, removed IPerspectiveState (MapModelState is now the same thing). Perspective transforms for the default fluid model.
Entry point: ModelLoaderRegistry
loader interface: ICustomModelLoader
custom model: IModel
ModelLoader is responsible for splicing into vanilla model system.
(you probably don't need to use it directly)
Interop with vanilla models isn't great yet
(vanilla models can't refer to custom ones as parents), will improve in
the future.
Includes loader for B3D models, with animation support
(net.minecraftforge.client.model.b3d).
Blender export plugin with compatible coordinate system:

OBJ loader is being written, will be included at some point in the
future. For now you can convert OBJ to B3D via blender, or wait.
