0026431: Can't cut a sphere from a cylinder

This branch contains fixes for 26675 and 26431 bugs. 1. Normalization has been eliminated. 2. Interfaces of AppDef_Compute::Parametrization(...) and BRepAlgo_BooleanOperations::SetApproxParameters() methods have been changed. 3. Overloaded methods for ApproxInt_Approx::SetParameters(...), TopOpeBRepTool_GeomTool::GetTolerances(...) and TopOpeBRepTool_GeomTool::SetTolerances(...) have been removed (because some fields of these classes are not used more). 4. Comments for some methods have been changed in BRepApprox_TheMultiLineOfApprox.hxx and GeomInt_TheMultiLineOfWLApprox.hxx files. 5. Some fields have been deleted from ApproxInt_MultiLine class. Kept members have become constant. 6. Interface of ksection DRAW-command has been changed. 7. Now, 2dintersect DRAW-command prints information about found segments. 8. Some code fragments have been rewritten to make them easier. 9. Algorithm of splitting WLine, which goes through pole of sphere has been improved. 10. Improve approximation algorithm in order to it will compute correct 2D- and 3D-tangent at the end of bezier constraints (including case when curve goes through or finishes on singular points). 11. Interface of IntPatch_WLine::Dump(...) method has been corrected. 12. Some methods for working with Walking-line are made more universal (available for both GeomInt and IntTools packages). 13. Problem in BRepLib::SameParameter(...) method has been fixed (see corresponding comment). 14. Small correction in Draft package. 15. Any outputs in IntPatch_Intersection::Dump(...) method have become disabled because they are useless. If anybody need in this outputs he/she will correct this method himself/herself. Adjusting some test cases according to their new behavior. Creation of new test cases. ---------------------------------------------------------------------------------------------------------------------------- Some explanation of new behavior of some test cases: 1. Regressions: a) blend simple X4 The problem is described in the issue #0026740. According to this description, the result on the current MASTER seems to be wrong indeed. b) boolean bcommon_complex C7 and boolean bcut_complex Q1 These test case use same shapes with different Boolean operation (COMMON and CUT). They are already BAD (on the MASTER). Now, some sub-shapes have become not-shared, simply. In my opinion, we shall apply new behavior of these tests. c) boolean bsection M3 The problem described in the issue #0026777 exists even on the current MASTER. d) boolean bsection M9 The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=26815#c47546. Here, we have really regression in the picture. e) boolean bsection N2 The problem is described in issue #0026814. f) boolean volumemaker G1 The problem is described in issue #26020. g) bugs modalg_1 bug1255 (and bug1255_1) The problem is described in issue #26815. h) bugs modalg_2 bug5805_18, bugs modalg_2 bug5805_42, bugs modalg_2 bug5805_46 The problem is described in issue #25925. i) bugs modalg_3 bug602 The problem is describes in issue #602. j) bugs modalg_5 bug24915 The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=25929#c48565. It is not fixed by this issue. k) bugs modalg_5 bug25838 The main reason is described in issue #0026816. ---------------------------------------------------------------------------- 2. Improvements: a) boolean volumemaker F9 b) bugs modalg_1 bug10160_3 c) bugs modalg_2 bug22557 d) bugs modalg_5 bug25319_1 (_2) e) draft angle G2 f) offset shape A1 g) offset with_intersect_80 N7
