Computing is unified. ComputeFastTol3d() method was deleted.
If intersection result contains 3D- and corresponded two 2D-curves then tolerance will be computed with using BRepLib_CheckCurveOnSurface algorithm (check same-parameter).
If intersection result contains only 3D-curve (getting 2D-curve can be switched off by users) then tolerance will be computed with using GeomAPI_ProjectPointOnSurf algorithm (projects some point of 3D-curve on the surface and finds maximal distance).
Some workarounds have been deleted.
Some test case have been changed.
1. JoinWLines algorithm has been improved.
2. Reference to the V-boundaries is deleted when computing step.
3. Decreasing the tolerance when computing parameters of WLine.
4. Adding boundary point is forbidden if it lies in prolongation of found ones.
5. Possible reason of exception has been eliminated.
6. Processing of critical point has been improved.
Test cases for this issue have been created.
Correction of some test case(s).
Test case bugs/modalg_6/bug26310_4 is added
Update of test-cases for issue #26310
