AccordionDrawer
Class InteractionBox

  +--AccordionDrawer.InteractionBox

public class InteractionBox

extends java.lang.Object

Draw and cache information about an onscreen rubberband box. Because we need to draw exactly this box again to erase it in XOR mode, we must cache the corner points instead of looking them up dynamically.
