- Upgrade Recast library to latest portable version
- Implement recast_qsort based on FreeBSD qsort.c to have
portable thread safe quick sort for use in conversion routine.
- Better default value for the Build Navigation Mesh operator
- Some declarations after statement left.
- Do not use static inline functions in MOD_navmesh. It produces errors
with msvc and not sure it's actually helps -- optimizer should
make it inlined itself.
