Bases can of course be orthogonal without the basis vectors being unit vectors, and vice versa. While we can (and apparently do in the SL code) represent bases as matrices, as long as the class is called something with "Matrix", its methods should adhere to the matrix terminology, of course, so it's fine to stick with the current name.
