261b7d9e8a 0028222: Intersection of two cylinders fails
1. The reason of exception has been eliminated.

2. Algorithm in IntPatch_WLineTool::JoinWLines(...) method has been modified in order to forbid join curves in the point where more than two intersection lines meet. More over, joining is forbidden if local curvature in the connection point is too big (see function CheckArgumentsToJoin(...) in the file IntPatch_WLineTool.cxx).

3. Interface of IntPatch_WLineTool::JoinWLines(...) method has been modified in order to reduce number of arguments.

4. Small corrections in IsSeamOrBound(...) static function has been made. Namely, check has been added if two boundaries are in the same period region but are too far each to other (see IntPatch_WLineTool.cxx, IsSeamOrBound(...) function, line # 532).

5. "Reversed" flag has been made local. Now, it is pure local characteristic: the algorithm decides itself, shall we reverse the argument order. This correction makes the algorithm more commutative (see issue #25404). However, IntPatch_WLineTool::JoinWLines(...) method can return non-commutative result.

6. Algorithm of searching small intersection curves has been improved.

7. New methods have been added in Bnd_Range class.

Some test cases have been adjusted according to their new behavior.

1. tests\bugs\modalg_6\bug26310_3
   tests\bugs\modalg_6\bug26310_4
   tests\bugs\moddata_2\bug235
   tests\perf\modalg\bug26310_1
   tests\bugs\modalg_5\bug24915

Logic of these cases has been changed. Mover over, additional check has been added in "bug26310_1" test case. Therefore, its performance will be slower than on the current MASTER.

2. tests\bugs\modalg_5\bug25292*

Scripts have been rewritten in order to make it more readable. Logic of these cases has not been changed.

7365fad60b 0026310: Very slow boolean cut operations on cylinders
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
