PING! (sound of large penny dropping)

No this isn't what I was doing, I think I tried the functions once
as a straight replacement for RotMatrix & hence the identity matrix
wouldn't have been set up (probably zero), somehow I got it into
my head that the functions would generate the required rotation
matrix from the angle.
