[API Review] RT-31256: Zero point

[Pavel Safrata]

Hello,
Jira: https://javafx-jira.kenai.com/browse/RT-31256

I just want to add

Point3D:
    /**
     * Point or vector with all three coordinates set to 0.
     */
    public static final Point3D ZERO = new Point3D(0.0, 0.0, 0.0);

Point2D:
    /**
     * Point or vector with both coordinates set to 0.
     */
    public static final Point2D ZERO = new Point2D(0.0, 0.0);

Regards,
Pavel
