public class LineAnnotationHandler
extends SelectionBoxHandler
implements ToolHandler

LineAnnotationHandler tool is responsible for painting representation of a line on the screen during a click and drag mouse event. The first point is recorded on mousePressed and the line is drawn from first point the current location of the mouse.
