You have missed the point. What I'm talking about has nothing to do with the
actual resolution of the image, but about the aspect ratio set using the up
and right vectors. The point is that you should be able to get a circular
fisheye even if your image isn't square (again, "square" has nothing to do
with the actual resolution, but about the aspect ratio set using the up and
right vectors).

This has always been the philosophy with other camera types such as
perspective and orthographic, so why should fisheye not follow that?
Remember that my proposed solution does not remove any functionality, only
expand.
