I still think this approach splicing it into the scale filter is an ugly hack (as the previous time it was submitted), and that the standalone filter (as I wrote a proof-of-concept for last time) would be more sensible.

(Though if everyone else really thinks that this is a good idea then I won't protest that hard.)
