## Summary of Changes
As reported in #7868 the function `CGAL::IO::write_PLY()` used in binary
mode does not correctly write the coordinates if the points are from a
kernel with exact constructions.
~~This PR applies `to_double()" to the coordinates.~~
~~After a discussion with @MaelRL we decided that the user is in charge
to pass a `vertex_point_map` as named parameter that does the
conversion. This is straightforward as we offer the
[`Cartesian_converter_property_map`](https://doc.cgal.org/latest/Property_map/structCGAL_1_1Cartesian__converter__property__map.html).~~
Moving back to the previous proposal: hardcode some to_double and
to_float casts such that we meet the requirements of the file format,
whatever the input.
As the problem is the same for the vertex normals we add a named
parameter `vertex_normal_map`.
### Todo
- [x] Fix the generic function `write_polygon_mesh()`. Currently it is
fixed for `Surface_mesh`
## Release Management
* Affected package(s): Stream_support
* Issue(s) solved (if any): fix#7868 and fix
https://github.com/CGAL/cgal/issues/7327
* License and copyright ownership: unchanged
* upcoming integration, update #9072 and test it
## Summary of Changes
Fix missing links in doc.
tentative TODO:
- [ ] Check all \`.+\(.+\).*\` --> stopped at BGL
- [ ] Plenty of wrong links for the overloaded functions like <em>A
shortcut to `CGAL::draw(vd2,
Graphics_scene_options_voronoi_diagram_2{})`.</em>, which points to
`CGAL::draw(T2)`.
## Release Management
* Affected package(s): Various
* Issue(s) solved (if any): https://github.com/CGAL/cgal/issues/7839
* Feature/Small Feature (if any): -
* License and copyright ownership: no change
## Summary of Changes
Added a small piece of code that generates an error message if verbose
is on and adding a face fails.
This fix is the bare minimum....
It would be nice to normalize all error messages and make them look
similar.
## Release Management
* Affected package(s): BGL
* Issue(s) solved (if any): fix#9034 partially. It partially fixes item
4. in the list of the bug report
* Feature/Small Feature (if any):
* Link to compiled documentation (obligatory for small feature) [*wrong
link name to be changed*](httpssss://wrong_URL_to_be_changed/Manual/Pkg)
* License and copyright ownership:
## Summary of Changes
I start removing some IO functions which are annoying to find in the
search box. More to come.
- [x] `CGAL::write_off()`
- [x] `CGAL::write_wrl()`
- [x] `CGAL::write_vtk()`
### Todo
- [ ] remove the test cases.
## Release Management
* Affected package(s): BGL, Surface_mesh, Point_set_processing
* License and copyright ownership: unchanged
