  Message : Add top-level state sync for Samplers. This also reformats the Sampler class to use a shared state struct with the implementation. It removes the call to sync the sampler state from the StateManagerGL::setGenericShaderState method, since it should all be handled at the front-end now. Also rename 'syncImplState' to 'syncState' methods.
