// Class : MatrixLens
// Description : A completely generic linear lens. This is provided
// for the benefit of low-level code that wants to
// specify a perspective or orthographic frustum via an
// explicit projection matrix, but not mess around with
// fov's or focal lengths or any of that nonsense.
