I finally got round to looking at this properly and have very quickly
realised it’s probably beyond me. In order to receive touch events we
need to migrate to XInput2, which seems to be completely different
from XInput1.

I don’t know how much work would be involved as I have no experience
with X programming, but I suspect it’s quite a lot.

I also don’t know if it would introduce compatibility issues with
older versions of X.
