/**
 * A {@code RepaintManager} that is designed to forward all calls to a contained
 * delegate. This class is designed for extension, such that subclasses should
 * override method as appropriate and allow the original repaint manager to
 * handle the rest of the work.

* Install a forwarding repaint manager: * *

 * RepaintManager manager = RepaintManager.currentManager(this);
 * RepaintManager frm = new ForwardingRepaintManager(manager);
 * RepaintManager.setCurrentManager(frm);
