I ComputePurgedWLine() function:
Excess points in walking line are deleted when:
1) Distance between neighboring points too small.
2) Points lie in one pipe without big jump on chord length.
III
Fixed problem with extremaPC with too close knot distribution to [minParam, maxParam] borders.
IV ApproxInt_Approx.gxx
New division criteria in intersection approximator.
III Test case
Test cases update to the new behavior.
Test case for CR21564
Correction of test cases for issue CR21564
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.
PCurve is extended to surface boundary forcefully.
It is made by finding some additional points (if it is possibly).
"bopcurves" DRAW-command returns number of found 3D-curves and (as an option) 2D-curve (see help for more detail information).
