/**
* SegmentedTorusMesh is based in TorusMesh, but allows cutting the torus in two
* directions, in order to have a banner parallel to an uncut torus.
* Based on a regular 2D TriangleMesh, mapped to a 3D mesh with the torus parametric equations
* Crop allows cutting/cropping the 2D mesh on the borders
* If crop ==0 then a regular torus is formed (thought with slight differences from
* TorusMesh)
