With doxygen release1.14.0 doxygen is a bit stricter regarding handling tables (not ignoring superfluous tags), it now leads to some warnings (and unexpected results).
## Summary of Changes
The testsuite of
[Triangulation](https://cgal.geometryfactory.com/CGAL/testsuite/summary-6.1-Ic-159.html?package=Triangulation)
has N's for some platforms. The test platforms have in common to use
boost_1_88_0, but with VC++ or clang on Windows I can't reproduce the
error with this version of boost.
In this PR I use the filter_iterator adaptor of CGAL, to see if the
boost filter_iterator is the problem.
## Release Management
* Affected package(s): Triangulation
* License and copyright ownership: unchanged
With doxygen release1.14.0 doxygen is a bit stricter regarding handling tables (not ignoring superfluous tags), it now leads to some warnings (and unexpected results).
That will suppress the warnings about `CMP0167` (from CMake 3.30):
```
CMake Warning (dev) at cmake/modules/display-third-party-libs-versions.cmake:37 (find_package):
Policy CMP0167 is not set: The FindBoost module is removed. Run "cmake
--help-policy CMP0167" for policy details. Use the cmake_policy command to
set the policy and suppress this warning.
```
```
save_Periodic_2_triangulation_2/class_c_g_a_l_1_1_periodic__2__triangulation__2.html:1420: parser error : Opening and ending tag mismatch: dd line 1420 and div
"This is an advanced function.">is_triangulation_in_1_sheet()</a></code> </div>
^
```
they are a consequence of the fact that a a command is not properly ended in this case we have a `\pre` command and its documentation states:
> The `\pre` command ends when a blank line or some other sectioning command is encountered.
and in this case the command is followed by the `\cgalAdvancedEnd` command that does not properly end the `\pre` command.
The same is valid in the other cases.
Newer versions of doxygen are more restrictive (and following the rules) in respect to the end comment of a HTML type of comment, i.e. `<!-- ... -->`, so parts of the paragraphs were missing
(Triangulation/index.html and Triangulation/group___pkg_triangulations_ref.html)
