public class JGraphPrintingScrollPane
Wrapper panel for a diagram/JGraph-pair that implements automatic sizing, backgrounds, printing and undo support. When wrapped in a scrollpane this panel adds rulers to the enclosing scrollpane. Furthermore, it automatically sets the minimum size and scale of the graph based on its settings.
