/* GLEW 1.10.0 emulation include header
 * this include file provides neccessary stuff to function with most GLEW programs.
 * library_glew.js is also provided to support extensions and error strings
 *
 * This file is based on GLEW (1.10.0) and linaro fork generated include files.
 *
 * What it lacks:
 * - Some constants and function declarations that are in GLEW 1.10.0 might be missing.
 * - The real glew-es fork also includes normal GL constants and function pointers, this does not.
 *
 * Authors:
 * - Jari Vetoniemi <mailroxas@gmail.com>
