  - drawSimpleEdge
```
protected void drawSimpleEdge(RenderContext<V,E> rc,
                              Layout<V,E> layout,
                              E e)
```
    Draws the edge e, whose endpoints are at (x1,y1) and (x2,y2), on the graphics context g. The Shape provided by the EdgeShapeFunction instance is scaled in the x-direction so that its width is equal to the distance between (x1,y1) and (x2,y2).
    
    Overrides:
    
    drawSimpleEdge in class BasicEdgeRenderer<V,E>
    
    Parameters:
    
    rc - the render context used for rendering the edge
    
    layout - the layout instance which provides the edge's endpoints' coordinates
    
    e - the edge to be drawn
  - stateChanged
