--Purpose: Creates an IntersectionSegment from two

|
-- IntersectionPoint. Oppos is FALSE if the 2 curves
|
|
-- have the same orientation. if ReverseFlag is True,
|
|
-- P1 and P2 are the point on the first curve, and on

|
-- the second curve. else, P1 is the point on the
|
|
-- second curve and P2 the intersection point on the

-- if First is set to True, P is the first point of

|
---Purpose: Returns True if the segment is limited by a first
|
|
-- point. This point defines the lowest parameter
|
|
-- admitted on the first curve for the segment. If
|
|
-- IsOpposite returns False, it defines the lowest

---Purpose: Returns True if the segment is limited by a last

|
-- point. This point defines the highest parameter

|
-- admitted on the first curve for the segment. If
|
|
-- IsOpposite returns False, it defines the highest
