04.pixmap_roamer/
   Creates a pixmap in a window and makes the pixmap 
   roam around by using a timeout

05.rootwindow_roamer/
   This example creates a pixmap directly on the root window, and 
   makes it wander about the root window using a timeout.  Note that you
   should iconify extra xterms when running this example, or you might not 
   see the little pixmap on the rootwindow.

06.image_tracking/
   This program puts up an image, and adds an event handler which
   is used to move a marker on the image.  Click on the marker and
   hold the button down to "drag" it across the image.  The position
   of the marker in the image is tracked, and a label object under
   the image updated to display the position of the marker and the
   pixel value at that location.
