  It certainly would be nice, but it's not possible because it's not
an affine transformation (even though it might look like it was).
  Affine transformations are all those transformation which keep a
straight line straight after the transformation. If the line would be
bent after the transformation, that's just not possible. (And here I'm
talking naturally about the ray we are tracing.)
