- Addition of `gp_Dir::D` and `gp_Dir2d::D` enums for standard directions (X, Y, Z, NX, NY, NZ)
- Constexpr/noexcept constructors for geometric primitives (circles, cones, cylinders, etc.)
- Enhanced axis placement classes with enum-based constructors
- Replacement of hardcoded direction values throughout the codebase
1. New testgrid "lowalgos/intss" has been created. It will contain all test cases on geometrical intersection of two surfaces ("intersect" DRAW-command) and two faces ("bopcurves" DRAW-command).
2. New test case for the issue #28493 has been created because the problem is not reproduced on MASTER.
3. Test case (lowalgos/intss/bug24472) for the issue #29501 has been modified in order to check loops of the resulting intersection curves.
