An EdgeFigure
implementation providing a Bezier curve line type. Clients should
first create an instance of BezierEdgeFigure
and then supply the Bezier control
points via the setControlPoints
method. This class uses the LineShape
wrapper class to provide an appropriate line-based Shape
object.

public BezierEdgeFigure(diva.canvas.Site tail, diva.canvas.Site head)
Creates a new BezierEdgeFigure
using the given sites. The control points are initialized to:
pt1 = tail point pt2 = (0,0) pt3 = (0,0) pt4 = head point
