+
+The overlay example
+
+This example program shows how to use OpenGL overlays with the Qt OpenGL
+Extension. It contains a QGLWidget with a relatively expensive
+redrawing operation, and rubber-band drawing in the overlay plane.
+Using the overlay has the advantage that the rubber-band may be drawn
+and erased without damaging the image in the main plane, so costly
+redraws are avoided.
