## Summary of Changes
Defaulting to Convex_hull_traits_3 instead of
Kernel_traits<Point_3>::type
Prevents crash for point sets with [collinear
points](https://gist.github.com/soesau/351a3fa69e550a27fa629fc8e085da6a)
## Release Management
* Affected package(s): Convex_hull_3
## Summary of Changes
The function did not move vertices in higher levels.
### Todo
- [x] Check if fixes have to be made in 2D as well
- [x] Check the other functions moving vertices in the hierarchy
classes.

## Summary of Changes
Behavior of QOpenGL.h changed, with 6.9.1 it does not provide APIENTRY
from windows.h anymore, but QT_APIENTRY instead
added redefinition of APIENTRY in qglviewer.h based on QT_APIENTRY
## Release Management
* Affected package(s): Lab, GraphicsView
## Summary of Changes
Added inactive list for deleted nodes (nodes cannot be deleted for now)
avoiding linear search time for node insertion during Orthtree build
Reusing indices in properties from deleted nodes for insertion of a
group of nodes (i.e., during Orthtree refinement) is deactivated. This
has no impact as nodes cannot be deleted anyway.
## Release Management
* Affected package(s): Orthtree, Property_map
## Summary of Changes
In theory in Mesh_3, a Steiner point cannot be hidden.
In practice with inexact constructions (even with the robust
circumcenter), it can happen that the Steiner point is hidden.
This case leads to an early exit of `RT3::find_conflicts()` which was
inconsistent with `facet_is_in_its_cz`
This PR fixes it
