// Each scene is associated with a unique scene token at creation time.
// This token can be used to create references from one scene to another
// or to create a renderer for a scene graph.
//
// Scene tokens should be kept secret.

// TODO(jeffbrown): This implementation is a temporary placeholder until
// we extend Mojo to provide a way to create tokens which cannot be forged.
