class ToOpenGLMatrix m where | Source |

There should be a big warning here about the different conventions,
hidden transpositions, and all the confusion this will inevitably cause...
As it stands,
glRotate t1 axis1 >> glRotate t2 axis2 >> glRotate t3 axis3
has the same result as
multMatrix (rotMatrixProj4 t3 axis3 .*. rotMatrixProj4 t2 axis2 .*. rotMatrixProj4 t1 axis1)
because at the interface of OpenGL and this library there is a transposition
to compensate for the different conventions. (This transposition is implicit
in the code, because the way the matrices are stored in the memory is also
different: OpenGL stores them column-major, and we store them row-major).
