In 5.9.2, "In addition to supporting an image on the background, a Component may now be drawn as the JGraph background for applications such as mapping. Some performance improvements have been made in the GraphLayoutCache relating to making cells invisible. In the model there have also been performance improvements around the functionality that removes cells."
