Refactoring of the Display Hierarchy:

Display can be any kind of display - image, text, whatever.

Displays have a DisplayPanel, which is contained in a top-level DisplayWindow, which may be a window, frame, internal frame, or a tab.

Keyboard, mouse and window events can be handled separately.

-- interface Display,
is extended by ImageDisplay (which has an AbstractImageDisplay) and TextDisplay (To do: OutputWindow will become one of these)

DisplayPanel is implemented by SwingImagePanel and TextDisplayPanel.

A DisplayWindow contains a DisplayPanel.

An implementation of all this is in SwingImageDisplay, SwingDisplayPanel and SwingDisplayWindow.

-- Created Separate EventDispatchers for Keyboard, Mouse and Window events. So, instead of

final EventDispatcher eventDispatcher =new AWTEventDispatcher(this, false);

we do this,

imgCanvas.addEventDispatcher(new AWTMouseEventDispatcher(this, false));
imgPanel.addEventDispatcher(new AWTKeyEventDispatcher(this));
window.addWindowListener(new AWTWindowEventDispatcher(this));
