 * Samples and returns point on the boundary of given 2D shape at normalized

 * @remarks
 * Currently implemented for:
 *
 * - {@link Arc}
 * - {@link Circle}
 * - {@link Cubic}
 * - {@link Ellipse}
 * - {@link Line}
 * - {@link Polygon}
 * - {@link Polyline}
 * - {@link Quad}
 * - {@link Quadratic}
 * - {@link Ray}
 * - {@link Rect}
 * - {@link Triangle}
 *
 * Note: For {@link Ray}, the `t` is interpreted as distance from the ray origin.
