## Summary of Changes
For file formats that expect floating point coordinates we convert on
the fly so that `CGAL::io::write_polygon_soup()` also works for polygon
soups with ` FT` which are non-float/double, e.g.
`Exact_predicates_exact_constructions_kernel`.
Additionally, we document the named parameter `point_map` as it was
missing.
