From 78636289b073d67209a20145ef0dc003f2d77db6 Mon Sep 17 00:00:00 2001
From: Sian Cao <yinshuiboy@gmail.com>
Date: Tue, 12 Apr 2016 11:36:51 +0800
Subject: Add GL_ARB_shader_texture_lod support
The patch is used to do lod biased texturing. I can achieve
faster blurring of images instead of using large blur radius.
