ANGLE worker context implementation is incomplete 

The worker context is not initialised with the sharegroup
  WorkerContext *DisplayEAGL::createWorkerContext(std::string *infoLog)

Need to also add a way to flush correctly after each worker task before task wait is notified

Need to also add a way to flush correctly after each shader object / program object creation.
