-- Adding a sequence of state with two possible values: 0 means the point is
-- inside the face, 1 - the point is on the bound of face. This is done to get
-- a proper result of method State(int), which always returned TopAbs_IN before.

-- that case, the parameter of the intersection point
-- on the line can be a negative value (greater than -Tol).

--
-- For an infinite line PInf and PSup can be
