        example programs using the printpixel object

1.printpixel_display/

  This program creates an image object, a position object to reflect the
  location of the mouse pointer in the image, and a printpixel object to
  print the values of the pixels surrounding that location.
 
  Note that you do NOT have to write an event handler to make the  
  printpixel object update; the fact that we have created an image object
  using the same file for it's data does the trick.  The image object will
  recognise pointer motion within it, and cause the printpixel object (and
  the position object as well) to be updated automatically.
