A helper to define singletons for InstancedShaders.
While treating an instanced shader as a singleton means that you can no longer create instances of that shader, it benefits from being able to use some extra functionality from InstancedShader and InstancedShaderBase.
| typedef std::shared_ptr<TShaderImpl> SingletonInstancedShaderBase< TShaderImpl >::TShaderImplPtr |
Helper typedef for a shared pointer to a TShaderImpl.
| typedef std::weak_ptr<TShaderImpl> SingletonInstancedShaderBase< TShaderImpl >::TShaderImplWeakPtr |
Helper typedef for a weak shared pointer to a TShaderImpl.

inlinestatic |
Returns the singleton instance of this shader, creating it if necessary.
