///
/// This model type is a thin wrapper layer on top of other layers.  It adds
/// some simple transforms (scaling and rotation) on top of other formats.
///
/// For instance, if you find another MD3 or OBJ model that you like but need
/// to transform, you can take the other model and wrap it with this class.
///
/// The Aesop game engine commonly uses this format to scale and rotate
/// Quake MD3 models.
