Btw, I suggest to create a macro that will i.e. generate smooth-mesh 
imitating superquadric ellipsoids.

Why? I think that this object implementation is broken:
1) it renders terrible slow (about 10-20 times slower then i.e. torus) 
especialy when pov must calculate intersections with it
2) it very often had problems/artifacts like mentioned above
3) both things get worse when using supperellipsoid in CSG
