public class NavigatedPanel
extends javax.swing.JPanel
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.KeyListener
```
Implements a "navigated" JPanel within which a user can zoom and pan. The mapping of the screen area to world coordinates is called "navigation", and it's NavigatedPanel's job to keep track of the navigation as the user zooms and pans. It throws NewMapAreaEvent to indicate that the user has changed the Map area, and the display needs to be redrawn. It throws PickEvents when the user double clicks on the panel.

NavigatedPanel has a standard JToolbar that can be displayed. It also implements a "reference" point and fast updating of the status of the mouse position relative to the reference point.

A user typically adds a NavigatedPanel and its toolbar to its frame/applet, and registers itself for NewMapAreaEvent's. When an event occurs, the user obtains a Graphics2D (through the getBufferedImageGraphics() method) to draw into. The AffineTransform of the Graphics2D has been set correctly to map projection coords to screen coords, based on the current zoomed and panned Map area. The renderer can use the AffineTransform if needed, but more typically just works in projection coordinates. The renderer can also get a clipping rectangle by calling g.getClip() and casting the Shape to a Rectangle2D, eg:
```
       Rectangle2D clipRect = (Rectangle2D) g.getClip();
 
```
Our "world coordinates" are the same as java2D's "user coordinates". In general, the world coordinate plane is a projective geometry surface, typically in units of "km on the projection surface". The transformation from lat/lon to the projection plane is handled by a ProjectionImpl object. If a user selects a different projection, NavigatedPanel.setProjection() should be called. The default projection is "Cylindrical Equidistant" or "LatLon" which simply maps lat/lon degrees linearly to screen coordinates. A peculiarity of this projection is that the "seam" of the cylinder shifts as the user pans around. Currently our implementation sends a NewMapAreaEvent whenever this happens.
