RepaintManager

This class manages repaint requests, allowing the number of repaints to be minimized, for example by collapsing multiple requests into a single repaint for members of a component tree.

As of 1.6 RepaintManager handles repaint requests for Swing's top level components (JApplet, JWindow, JFrame and JDialog). Any calls to repaint on one of these will call into the appropriate addDirtyRegion method.
