p Various geometric informations on the graphic graph.
This class extends the GraphMetrics to provide not only metrics on the graphic graph but also on the rendering canvas, and allow to convert from graph metrics to canvas metrics and the reverse.

Here we call the canvas "view port" since this class allows to place a view port inside the graph in order to zoom and pan the view.

    camera.pushView(graph, g);
    renderGraphElements(g);


    if (style.getStrokeMode() != StyleConstants.StrokeMode.NONE
        && style.getStrokeWidth().value != 0) {
      GraphMetrics metrics = camera.getMetrics();
      Rectangle2D rect = new Rectangle2D.Double();
      double px1 = metrics.px1;
      Value stroke = style.getShadowWidth();


      rect.setFrame(metrics.lo.x, metrics.lo.y + px1,
          metrics.size.data[0] - px1, metrics.size.data[1] - px1);
      g.setStroke(new BasicStroke((float) metrics.lengthToGu(stroke)));
      g.setColor(graph.getStyle().getStrokeColor(0));
      g.draw(rect);
    }


    camera.popView(g);
