To further clarify along with what the others said, vrotate(A,B) doesn't
rotate objects, it rotates vector A by degree rotation B.  What you want is
the opposite, you know the resultant vector and the rotated vector (normal,
A), you need to find the corresponding rotation B which is what the
function described by Warp does.
