For the record, I saw the email and will review (and merge if no problems)
your code. I have had not much time this week, but hopefully it will be
better next week.
For git authorship, do you confirm I should use the name and email as used
on this mailing list?

As for the GEGL operation discussion, I definitely see how cool it would be.
But if you say it would remove some features, of course we could discuss
how to make the best out of both worlds. I don't know enough about this
plug-in yet to be 100% relevant though. :-)

Here is what I have done:

You are more than welcome to contribute to the manual too. The source is
there: https://gitlab.gnome.org/GNOME/gimp-help

Same as we welcome patches for GIMP, we also do welcome patches for the
manual. :-)
