public class ImageDisplay
Encapsulates a image displayer, which tracks the user's "current location" and shows it using graphical feedback (approximating a "+" sign on the graphical display). The imager displayer is used as a component of the PictureExplorer. Copyright Georgia Institute of Technology 2004
