rasterizing screen pieces

[Mark Weiser]

Vince Guinto mention that he did not want to use the screendump x and y
coordinate parameters because he did not know how to find them.  The
wonderful little hack "eyes", when closed (or opened--the form that
doesn't show the eyes) instead prints the continually updated screen
coordinates of the cursor.  That might help.  I believe the titan.rice.edu
sun server has the "eyes" source.
