Public NotInheritable Class CubicBezierBuilder 
   Inherits SegmentBuilder
   Implements System.IDisposable 
Remarks
Use the CubicBezierBuilder class to to create and/or modify a CubicBezierSegment shape. A CubicBezierSegment is based upon the parent Segment class. The Segment class is immutable which means that you can not change its shape once it is created. Hence, the CubicBezierBuilder provides the way to make changes when working with a CubicBezierSegment. Use the CubicBezierBuilder.ToSegment method to get the CubicBezierSegment from the builder.

A cubic Bezier curve is a non-linear segment defined by four control points. The Bezier curve starts at control point 0 (start point) and ends at control point 3 (end point). The start point and control point 1 define the tangent at the start point. Control point 2 and the end point define the tangent at the end point. The length of these tangent lines and position of the 4 control points determines the shape of the created Bezier curve.
