BRepMesh_Classifier: Two-pass approach for intersection check with possibility to run it in parallel mode.
First pass - bounding boxes of segments are checked for overlapping;
Second pass - intersection point is calculated in case if overlapping is detected.
Make NCollection_UBTree::ChangeLastNode() exported due to compilation error on Linux platform.
Reason: method does not depend on template parameters, so it should be available.
Revert previous change and try to use another trick for Linux
Fix compilation warning on MacOS: remove redundant constant
Fix regressions: do not consider insignificant loops in case of self intersections on the same wire.
More sugar solution for compilation errors on NCollection_EBTree on Linux
