Summary0028690: Section algorithm produces micro edge
DescriptionThis use case is given from the test boolean bsection M8. Two neighboring faces do not share common edge, and thus they are interfering. The section operation produces a micro edge build on one vertex with length 5.62798e-005.

    0028690: Section algorithm produces micro edge
    
    In BOPAlgo_PaveFiller algorithm, prevent creation of vertex-edge interference if this vertex already has interference with one of vertices of this edge. This way we avoid creation of micro edges that are unwanted in the result shape.

 I have created the new version of the fix and 3 test cases:
bugs/modalg_6/bug28690,bug28690_1,bug28690_2.
The 2nd test does not work with this fix. It needs further improvement in PerformVE so that to check vertices coincidence after updating their tolerances.

Another case when non-resolved interference between vertices leads to invalid result of Boolean operation:
