IGeCurveOffsetCurve(GeLength)Remarks
The positive direction of offset at a point on the curve is taken to
be the right-handed normal to the tangent vector at that point.
So if the tangent vector at a point on the curve is (x,y), the
positive direction of offset will be (-y,x).
The curve may be offset in either of two directions by specifying a
positive or negative offset distance.
