HdInstanceRegistry is a dictionary container of HdInstance.
A central registry of all GPU resources.
Class to identify a texture file or a texture within the texture file (e.g., a frame in a movie).
Token for efficient comparison, assignment, and hashing of known strings.
Functor to use for hash maps from tokens to other things.
