public static void autoZoomViewer(VisualizationViewer<?, ?> vv,
LayerViewer<?, ?> home, Directions direction) {
if (vv == null || home == null)
return;
// reset transforms
MutableTransformer layoutTrans = vv.getRenderContext()
.getMultiLayerTransformer()

Dimension dim = vv.getSize();
Rectangle2D.Double graphBounds = home.getGraphBoundsCache();
CrossoverScalingControl scaler = new CrossoverScalingControl();
// Scale using crossover scaler, so vertices will not grow
// larger than they are in original
