In <https://gitlab.com/inkscape/inkscape/-/issues/784#note_343293612>
they seem to demonstrate a misunderstanding about lib2geom's license.
That commenter thinks that lib2geom is GPL2+, when it's actually
LGPL-2.1 or MPL-1.1.

However, gnu.org says that LGPL-2.1 is compatible with GPL2 and GPL3. So
maybe it's fine; I don't know. I think we should ask FSF for advice
