OpenGLRaw21

The intersection of OpenGL 2.1 and OpenGL 3.1 Core.

This package simply reexports a subset of the parts of OpenGLRaw which are compatible with OpenGL 2.1. The idea is that you can have greater certainty about compatibility with less capable graphics cards by only importing Graphics.Rendering.OpenGL.Raw.Core21 and the exact modules for whatever additional extensions you need.
