+
+  A graphics example using pre-window frame buffers.  The example shows
+  three windows containing text moving around, crossing each other from
+  "above" and from "below".  The example application is NOT updating the
+  windows any anyway!  The application is only changing the window
+  position.  The windows are being updated from the per-winidow
+  framebuffers automatically.
+
+  This example is reminescent of Pong:  Each window travels in straight
+  line until it hits an edge, then it bounces off.  The window is also
+  raised when it hits the edge (gets "focus").  This tests all
+  combinations of overap.
+
+  NOTE:  A significant amount of RAM, usually external SDRAM, is required
+  to run this demo.  At 16bpp and a 480x272 display, each window requires
+  about 70Kb of RAM for its framebuffer.
