  Exactly. As scaling by zero is illegal, then an error should be issued,
as with all illegal values.
  Think about this:

camera { look_at 0 }

  Having the camera location and look_at in the same point is illegal, and
thus an error is issued. POV-Ray doesn't (and shouldn't!) assume that
"oh, the user just mistyped this number, I'll convert it to 'look_at z' for
him".
