A specialized PropertyAnimation that defines an animation between two coordinates .
默认情况下, latitude 的 coordinate is animated in the direction of shortest (geodesic) distance between those coordinates. Since CoordinateAnimation uses Mercator map projection, the latitude animation is always between -90 and 90 degrees. The longitude animation path is not limited and can go over 180 degrees in both west and east directions.
The direction property can be set to specify the direction in which the longitude animation should occur.
