I don't know how often you are using GL11, however from my understanding direct calls should not be being made anymore. I only noticed it in your last commit in this file. There's a thread on the minecraft forums that explains why these calls should not be made any longer as of 1.8. I attempted to fork the repository and make these changes myself, however attempting to run "gradle setupDecompWorkspace eclipse" resulted in an error

Alright, noted! I'll remedy this once I get back.
