* Wisdom from Apple engineer in reference to UT2003's OpenGL performance:
* "You are blowing a couple of the internal OpenGL function caches. This
* appears to be happening in the VAO case. You can tell OpenGL to up
* the cache size by issuing the following calls right after you create
* the OpenGL context. The default cache size is 16." --ryan.
