bug#6130: 23.1; artist-mode spray-can malfunction

[busk]

I get a malfunction with the artist-mode spray-can when my drawing
goes "over" the borders of the frame, which manifests itself thusly:
It doesn't stop drawing on that particular are, but rather keeps
filling #'s in an area where I drawed until emacs is
killed. "Activating" another frame belonging to the same emacs process
moves the behaviour to that frame. Activating the mini-buffer makes it
draw in the minibuffer. Confirmed this on three different machines
with different releases of the ubuntu gnu/linux distribution and three
different releases of emacs (22.2.1, 23.1.1 and 23.1.50), and this
misbehaviour does not exist in 22.2.1, at least. I have not been able
to test this on a bzr snapshot, however, so in theory this might
already have been discovered and fixed, I guess.
