Description

Returns the first Inflection Point of the Bezier Curve, or returns an Empty Point if no Inflection Point Exists.  An Inflection Point occurs where the sign of the Curvature changes.

Remarks

Most Bezier Curves have 0 or 1 Inflection Points, but a few constructions result in Bezier Curves with 2 Inflection Points.  For these Bezier Curve, the only way to find both Inflection Points is to Reverse the Orientation of the Bezier Curve and call QueryInflectionPoint a second time.  If the Inflection Points are not equal, the Bezier Curve has two Inflection Points, otherwise, it only has a single Inflection Point.
