This annoyed me so much, though, that I researched it a tiny
bit more.  The Img extension, as it happens, can snapshot a
canvas into a photo, and Tkinter itself can report on the
pixel values in a photo image.

That's as good as it gets, apparently.  What I don't know is
whether Tkinter supports Img at all; I must confess that I'm
only aware of its availability for Tcl/Tk.
