	BRepClass_FaceExplorer (const TopoDS_Face &F)
Standard_Boolean	CheckPoint (gp_Pnt2d &thePoint)
	Checks the point and change its coords if it is located too far from the bounding box of the face. New Coordinates of the point will be on the line between the point and the center of the bounding box. Returns True if point was not changed.

	Should return True if the point is outside a bounding volume of the face.
Standard_Boolean	Segment (const gp_Pnt2d &P, gp_Lin2d &L, Standard_Real &Par)
	Returns in <L>, <Par> a segment having at least one intersection with the face boundary to compute intersections.
Standard_Boolean	OtherSegment (const gp_Pnt2d &P, gp_Lin2d &L, Standard_Real &Par)
	Returns in <L>, <Par> a segment having at least one intersection with the face boundary to compute intersections. Each call gives another segment.
