Workaround for I915 graphics cards which have horrible GL shader support.
Summary:
- GLEW doesn't load the GL shader functions, so we have to load them ourselves
- Replace our varying vec2 with glTexCoord[0].st
- Replace our uniform mat3 with manual matrix multiplication
BUG=33329
TEST=try it out on anything with an I915
