I'm not sure we want to allow direct access to the innards of how Emacs
utilises GTK widgets.  That way lies madness.

I've already discussed this with the EAF developers.  Until Qt gains the
ability to not select for TouchBegin, TouchUpdate and TouchEnd, EAF will
likely not work on XInput2 builds.

I will work on it eventually, which will be before the release of Emacs
29.
