Yes, but it has other side effect: creating illuminated line despite being in shadow
when cut, so I'm going to actually increase the requested precision. The radius of
7000 (for object of size 14) could be reduced to a radius of 700 without significant
visible effect.

Experimenting now with the uv-mapping. The naive usage of the normal does not seem
good for nearly flat section.
