Yep, I was merely pointing out the change with various ways of rendering it,
I've known about the position of 'orthographic' for a while now and just
wanted to emphasize that as being part of the whole thing about the camera
having differences too, not just the superellipsoid.
It's very noticeable how that shape can be quite slow to render sometimes,
would be great if someone had a new and better method of doing it.  Like the
lathe speedup was.
