public class DisplayItem

extends JComponent

implements SwingConstants, ActionListener

DisplayItem is the core component of the display API used to control the items painted on any of the Panels(mainly however the globalCanvas). The functionality of this class is through the simplification of tasks such as adjusting image saturation, brightness, fading paintable object in and out, etc. The objects supported by this class are listed in the table below with their default values listed below.

Supported DisplayItems and their default values
Object:	AlphaDirection:	Brightness:	Color:	Stroke:	Step:UP/DOWN
ClientNode	NA	NA	NA	NA	NA
ServerNode	NA	NA	NA	NA	NA
Image	UP	1.0f	NA	0.5f	0.2f/0.075f
ImageIcon	UP	1.0f	NA	0.5f	0.2f/0.075f
Line2D	UP	1.0f	Color.blue	0.5f	0.15f/.1f
