64e8b010af 0031552: Bad performance of intersection of cylindrical surfaces
Adjusting parameters of algorithm depending on axes and parameters of cylinders is added in order to reduce computation time

Test case added: tests/lowalgos/intss/bug31552

tests/perf/modalg/bug26310_1: test case corrected according to current state of algorithm

624c599cd3 0029359: Approximation algorithm computes multidimensional distance in Euclidean space incorrectly
Wrong distance computation has been corrected.

Some test-cases have been corrected according to their new behavior. Namely, built (by approximation algorithm) curve(s) has changed its geometrical position.

1. tests/blend/simple/X4

It is not a regression because the result is not correct on both MASTER and FIX (see explanation in the issue #26740). This problem is expected to be solved after porting Fillet-algorithm to new Boolean operation. Old Boolean operations do not cover Edge-Edge tangent-zone by vertex.

2. tests/bugs/modalg_6/bug27341_318

"checknbshapes" has been deleted in order to avoid non-stable behavior (see issue #29360) of this test case. New result is OK on both Linux and Windows platform.

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.

   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.

44fae8b193 0027691: Remove dchrono from all test cases and move its to perf group
Remove performance comparing with hardcoded value.
Test cases for performance of some commands were moved to perf group.

Updated documentation.
