broken. I don't know what I thinking when I plugged in 2*finesine[pitch]
  for Hexen's lookdir, because that's totally wrong. Not only is the
  magnitude far too low, but it also aims in the opposite direction you
  are looking. The new code only attempts to be close to Hexen's original
  while looking straight ahead and extrapolates that to other angles using
  proper 3D math.
