aml 0cbfb9f151 0021564: Intersection of two planar faces produces curve with too many poles
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
