public abstract class AbstractWormhole2D<P extends Position2D<out P>>
 implements Wormhole2D<P>
                    
```
Partial, abstract, implementation for the interface Wormhole2D. This implementation considers the particular case of the view as an entity into the sceern-space: the y-axis grows on the bottom side of the screen. This abstract class is independent from the 2D graphical component wrapped.
