public class TreeCanvas
extends java.awt.Canvas

Canvas on which to paint the tree. Does not work with Panel replacing Canvas. ScrollPane needs to hold a component which is not derived from Container (apparently). The canvas needs to be as large as the tree so that a scrolling container could view ALL of the tree
