DESCRIPTION
A printpixel object provides a mechanism which will track
pointer movement in an image object and print the values of
the pixels in the area under the pointer.
It was designed for use in conjunction with an image object.
The printpixel object is made up of one or more
(width x height) sets of label objects. The background of
each label is the color in which the pixel appears.
