1. Supperellispoid is not a roudned box. Are you aware that your macro is not a
replacement to supperelipsoid ?
2. Have you noticed similiar macro in official distribution ? Look at
http://www.povray.org/documentation/view/261/

I know a superelipsoid is not a rouded box, but i only use superelipsoids
for rounded boxes.

I had not noticed it, but someone else has told me to have a look at
shapes.inc (after i posted my own version). So i know my macro doesn't bring
anything new, but it was still a usefull macro practice.

Next time i think of something usefull, i will check the manual to see if it
already exists :-).

And it's been part of the Thoroughly Useful Macros since their
inception.
