OriginUpdateListener

```
public interface OriginUpdateListener
```
Objects that handle geographic objects should implement this interface. As OpenGL works with 32 bit float of limited numerical resolution coordinates should be transformed to a local origin. The OriginData structure contains necessary information about the origin, together with convenience methods for transformation
The PositionOrientationProvider will maintain the origin, and call the originChanged(OriginData) method as necessary. Implementing classes should recompute (and possibly reload) all their geographic data when this is called.
