PMP: compute_face_normal() of degenerate faces

3

## Issue Details In [this testsuite](https://cgal.geometryfactory.com/CGAL/testsuite/CGAL-5.6-Ic-38/Polygon_mesh_processing/TestReport_gimeno_ArchLinux-clang-Release.gz) we get an assertion that the normal of a degenerate face is not the null vector. It seems that the algorithm does not check...

PMP: Fast clipping with a plane

1

## Summary of Changes When we clip with a plane no need for fast box intersection. This is work in progress as there is no clean API. I even break...

Nef_3: Fix conversion to a FaceGraph

## Summary of Changes Fix the case of surfaces with borders. Then they may be incident to only the unbounded volume which so far was ignored. ## Release Management *...

## Summary of Changes Setting the seed as it was in [this testsuite](https://cgal.geometryfactory.com/CGAL/testsuite/CGAL-5.5-Ic-70/Periodic_2_triangulation_2_Examples/TestReport_lrineau_Ubuntu-latest-GCC6.gz) I can reproduce the assertion. This is not a fix. ## Release Management * Affected package(s): Periodic_2_triangulation_2

Unbalanced kdtree

## Summary of Changes Inserting a segment as constraint more than once may cause problems when there are intersections. This PR addresses it in the `insert_constraints()` function. We might add...

CORE: Use boost::multiprecision::number API (WIP)

13

## Summary of Changes Currently CGAL_Core uses the low level API of GMP for `BigInt` and `BigRat`. In this PR I replace this with the `boost::multiprecision::number` API, so that we...

NewKernel_d: Failure in a testsuite

1

## Issue Details In the master testsuite of [NewKernel_d ](https://cgal.geometryfactory.com/CGAL/testsuite/results-5.5-I-79.shtml#NewKernel_d) we have an assertion in the VC2022Preview teststuite. A 4D circumcenter is not computed correctly. These tests were not performed...

Nef_3: Allocate a big enough vector for the nodes of the K3_tree

10

## Summary of Changes Replace the `boost::container::deque nodes;` by an `std::vector` and reserve (too much) . ## Release Management * Affected package(s): Nef_3
