Thatʼs correct. The real solution is 'stop using XFT', but I donʼt
think we can require cairo just yet, much as Iʼd like to do so.

Eli, we could install my patch to filter out all colour fonts (see
<https://lists.gnu.org/archive/html/bug-gnu-emacs/2019-11/msg00409.html>),
that should reduce the amount of whack-a-mole required.
