It fixes `HexiCosPot-1.off`.
The explanation of the bug: `split_graph_into_polylines` can reverse the orientation of a polygon
Actually, that was not a bug. The issue is that the simplex traverse in 2D is currently buggy. With a bbox, that passes.
The data set was not coplanar, but a few vertices were missing from the initial CDT.

There was a warning: ``` Triangulation_3/include/CGAL/Constrained_Delaunay_triangulation_3.h:1841:5: warning: this statement may fall through [-Wimplicit-fallthrough=] [build] 1841 | } // dim 2 [build] | ^ ``` and for once that was a warning about a real bug!
The files are even repaired on the fiy.
For the moment, I selected: - num_vertices < 10000 and - "solid" As for the meaning of "solid", quoting Zhou, Qingnan, et al. "Mesh arrangements for solid geometry." ACM Transactions on Graphics (TOG) 35.4 (2016): 1-15.: > Solid meshes are free of self-intersections, degenerate triangles > or duplicate triangles, and their generalized winding number field > is either zero or one.
... instead of applying random selection of buckets.
`Surface_mesh::collect_garbage` uses swaps, and this it modifies the order of elements of the mesh.
That was more difficult than I expected!

- rename the meta-function, and the type alias - rename the template parameter `Geom_traits` to `Traits`
