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 containing 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.
