	I have an application where the results of a calculation can be
displayed as text or as a graph (PICT).  To display the results, I would
like to have a text window and a PICT window open, and allow the user to
click on a line in the PICT, retreive some information about where he
clicked, and then center the text window around that point.

	Any suggestions on how to get information on where a mouse-down (up)
with regard to a structure (line, rectangle, etc) in a PICT?  This seems
to happen all the time when draw programs move parts of the picture.
