Summary

Make javafx.geometry.Point2D andjavafx.geometry.Point3D implement javafx.animation.Interpolatable<T> in order to be able to interpolate over them.

Problem

Point2D and Point3D are containers for double data (x, y, z). Since they do not implement Interpolatable<T>, interpolation must happen over their internal values, which is cumbersome.

Solution

Make Point2D and Point3D implement Interpolatable<T>.

Specification

The class definitions now declare implements Interpolatable<T>:

public class Point2D implements Interpolatable<Point2D>

public class Point3D implements Interpolatable<Point3D>

The following method was added to Point2D:

/**
 * {@inheritDoc}
 *
 * @since 13
 */
@Override
public Point2D interpolate(Point2D endValue, double t)

The following method was added to Point3D:

/**
 * {@inheritDoc}
 *
 * @since 13
 */
@Override
public Point3D interpolate(Point3D endValue, double t)
