1472 * Wisdom from Apple engineer in reference to UT2003's OpenGL performance:
1473 * "You are blowing a couple of the internal OpenGL function caches. This
1474 * appears to be happening in the VAO case. You can tell OpenGL to up
1475 * the cache size by issuing the following calls right after you create
1476 * the OpenGL context. The default cache size is 16." --ryan.
