+backed-up windows</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<section><title>Description</title> <p>This example demonstrates how to implement
+a backed up window. </p> <p>It implements freehand drawing in a similar way
+to the <filepath>PtBuffer</filepath> example, using the pointer move buffer.
+However, in this example, the window which may be drawn to is an <codeph>RBackedUpWindow</codeph> rather
+than an <codeph>RWindow</codeph>. This means that any drawing is redrawn automatically
+if it becomes covered up and then uncovered: the backed-up window receives
+no redraw events. The example includes a small window which can be dragged
+around the screen to illustrate this. </p> </section>
