The patch lives in my `patch' repo along with other questionable stuff
[1].  Using an external tool is in line with other transforms page
already does, I think it makes more sense, but such a tool must be
imported first.  Since it would be useful to have outside of page for
image manipulation, I also think that that would be more useful than
attempting ghostscript black magic.  Technically, an implementation of
pico (like [2]) can do that kind of stuff and might be neat to have; I
am not really happy with my implementation and would have to revisit
it first, but if there's interest, I can do that.  Otherwise, iirc
Sigrid also has some image filters that could be interesting, besides
