public class BezierPath
extends VectorList<BezierNode>
implements Shape

A BezierPath is defined by its nodes. Each node has three control points: C0, C1, C2. A mask defines which control points are in use. At a node, the path passes through C0. C1 controls the curve going towards C0. C2 controls the curve going away from C0.
