There is another solution possible, and one that will make a much-desired
feature possible: we can make the krita canvas of unlimited size with the
image projected onto it, but not in a separate canvas widget. If we do that, we
can also control the rotation of the canvas (which people with tablets
really want), I can reinstate my code where you could see which parts
of layers were moved outside the image boundaries. (Both features to be
implemented after 2.0 is released, of course!)
