Changes:
class BOPAlgo_WireSplitter
static function:
Standard_Boolean RefineAngle2D(const TopoDS_Vertex& aV,
                               const TopoDS_Edge& aE,

                               Standard_Real& aA)
The contents of Domain 2D for the straight line has been changed.

class BOPTools_AlgoTools2D
method:
void BOPTools_AlgoTools2D::AdjustPCurveOnFace
  (const TopoDS_Face& aF,
   const Standard_Real aFirst,
   const Standard_Real aLast,
   const Handle(Geom2d_Curve)& aC2D,
   Handle(Geom2d_Curve)& aC2DA)
The treatment of cylindrical surfaces has been changed taking into account
existing values of tolerances of the edges.
