A stereoscopic camera for PovRay.
   http://local.wasp.uwa.edu.au/~pbourke/modelling_rendering/stereopov/
Implemented as
   camera {
      stereoscopic
      location ...
      up y
      right ...
      angle ...
      sky ...
      look_at ...
      zeroparallax ...
      eyeoffset ...
   }
Now I know there are various ways at doing stereoscopic projections in PovRay,
unfortunately most are either plain wrong, only create stereo pairs suited to
"eye trick" viewing, create images pairs that are hard to view for extended
periods, or are not couched in terms of parameters stereoscopic content
producers need. While the above requires source code modification and
recompiling, it at least creates stereo pairs correctly and with a natural
specification.

ps: This is the first time I've modified the PovRay source, hope I've taken the
right approach and style.
