## Summary of Changes
Versions >= 9 of VTK trigger the following CMake warning using CGAL's
CMakeLists
```
CMake Deprecation Warning at C:/dev/VTK-9.2.2/build/lib/cmake/vtk-9.2/vtk-use-file-deprecated.cmake:1 (message):
The `VTK_USE_FILE` is no longer used starting with 8.90.
Call Stack (most recent call first):
CMakeLists.txt:32 (include)
```
I suggest this modification of the CMakeLists of Mesh_3 examples, that
also requires moving to VTK 9 (9.0 was released in 2020).
If this modification and new requirement are validated, I can apply the
change everywhere.
## Release Management
* Affected package(s): Mesh_3 for now
* License and copyright ownership: unchanged
## Summary of Changes
Important various fixes and improvements, from an experimental branch of
mine about CDT_3.
- <s>remove CMake warnings about `VTK_USE_FILE`</s> (our testsuite tests
with [VTK-8.2](https://docs.vtk.org/en/latest/release_details/8.2.html),
whereas
[VTK-9.0](https://docs.vtk.org/en/latest/release_details/9.0.html) was
released four years ago).
- make `Circulator_from_container` compatible with ranges (instead of
just containers)
- `Hash_map` is move-constructible and -assignable
- add preliminary support for C++20 concepts and `<format>`
- [x] add `Compare_angle_3(Point_3, Point_3, Point_3, Point_3, Point_3,
Point_3)` (with six points) **TODO: needs doc**... will be handled later
in issue #8219
- [x] **breaking changes:** add `Compare_xy_2` to
`TriangulationTraits_2` <s>TODO: needs announcement</s>
- fix `Compact_container` time stamp feature
- [x] commits from #7410 **That is probably a problem, to be fixed.**
**fixed in #7410 and then my the merge
https://github.com/CGAL/cgal/pull/8170/commits/70464ea107dcf9e32a338ed5c307897f1cb1fcf8**
- add `CGAL::Scope_exit`, `CGAL::make_scope_exit`, for CGAL developers
(undocumented)
- add an overload of `make_sorted_pair` with only one pair-like argument
- improve `CGAL::IO::Output_ref` and `oformat`
- perf improvements in
`TDS_3/include/CGAL/Triangulation_data_structure_3.h` (`is_edge` is 7
times faster)
- <s>perf improvement in
`Triangulation_2/include/CGAL/Triangulation_2/internal/Polyline_constraint_hierarchy_2.h`
(with the use of `unordered_flat_map` from Boost>=1.80</s>
- less filter failures in `Triangulation_segment_cell_iterator_3`
- add `Triangulation_3::is_facet(u, v, w)` (without `, c, i, j, k`)
## Release Management
* Affected package(s): Installation, T_2, TDS_2, T_3, TDS_3, SMDS_3,
Kernel, STL_Extension, Stream_support
* Feature/Small Feature (if any):

## Summary of Changes
While the Polyhedron demo can read `*.nii` files there is no example in
`examples/Mesh_3/`.
This PR adds the functionality to the example that uses vtk to read
DICOM data.
This is triggered by [this
question](https://stackoverflow.com/questions/77331075/is-there-an-easy-way-to-convert-from-nifti-nii-image-format-to-inr)
on stackoverflow.
- [ ] Support of `*.nrrd` format
- [ ] example for segmented images
- [ ] Add example data for the file formats.
## Release Management
* Affected package(s): Mesh_3
* License and copyright ownership: unchanged
(from 745 to 893 in my experiments)
so testing their number wrt a reference value does not make much sense
This commit changes to test not to test meshing without comparing nbv and nbf
in parallel mode
This reverts commit 06d272169f.
There may be an inconsistency between exact and inexact computations,
in the facet encroachment rule
This code was leading to a local infinite refinement loop during cells refinement
