OpenGL Support module

This module provides wrapper functions for a couple of OpenGL functions which simplify the way to pass Eigen's object to openGL. Here is an example:

// You need to add path_to_eigen/unsupported to your include path.
#include <Eigen/OpenGLSupport>
// ...
Vector3f x, y;
Matrix3f rot;
 
glVertex(y + x * rot);
 
Quaternion q;
glRotate(q);
 
// ...
