/**
 * The MapWindow is a window with the basics - MapBean,
 * MouseDelegator, SelectMouseMode, LayerHandler. It can be used to
 * draw stuff into if you add a layer to it that handles what you want
 * to render. The SelectMouseMode will automatically direct mouse
 * events to the layer if it is set up to receive "Gestures".
 * <P>
 * 
 * If you want to add an object that needs to set itself to a
 * particular location on the frame, i.e. the ToolPanel or
 * InformationDelegator, you have to do the layout management yourself
 * with the MapWindow. The OpenMapFrame has an idea of where it wants
 * those components to go, but the MapWindow doesn't.
