| Yes, because it is already possible in an indirect way.

That's simply a image formatting thing, nothing to do with the ray trace
itself anyway. So the actual fix that could work is to somehow expand the
partial render to fit the full resolution by predicting a field of view.
Then you lose part of the fisheye field. If wanting a complete 360 degree
field shown as rectangular that requires greater than 360 degree field...
how can that be done then?
It would have limitations anyhow.
