public class ViewerPanel
extends JPanel
implements OverlayRenderer, PainterThread.Paintable, ViewerStateChangeListener, RequestRepaint
```
A JPanel for viewing multiple of Sources. The panel contains a canvas and a time slider (if there are multiple time-points). Maintains a render state, the renderer, and basic navigation help overlays. It has it's own PainterThread for painting, which is started on construction (use to stop the PainterThread.
