____________________________________________________________________________________________________________

DESCRIPTION
       This package provides a command to take snapshots of arbitrary canvases.

API
       ::canvas::snap pathName
              Takes  a  snapshot of the canvas pathName. The result is the name of a new Tk photo image con-taining containing
              taining the snapshot.

              Note that this command has a side-effect. To avoid having white rectangles where other windows
              may  overlap the canvas this command forces the toplevel window the canvas is in to the top of
              the stacking order.
