0032395: Mesh - possible mistake in BRepMesh_Delaun::isVertexInsidePolygon
The method BRepMesh_Delaun::isVertexInsidePolygon classifies a point inside 2D polygon calculating cumulative angle from the point to all segments.

I found out that for a CCW polygon the angle computed by that procedure will be equal to -2PI. However, the final condition checks the angle for equality to +2PI.

It is needed to analyze the code more thoroughly, try to correct it and conduct regression tests to see if it becomes better.
