Re: Expose touchpad sensitivity in wsconsctl

[Brennan Vincent]

People who prefer flatter profiles are not as rare as one might think, 
cf similar discussions on Libinput:
https://bugs.freedesktop.org/show_bug.cgi?id=89485
I found setting it to 4 gives best results (it was 16 by default) so I 
wouldn't want to totally remove it either.

Feel free to not merge this patch if you don't want it; I will not be 
offended. As long as I have things working how I like on my own system :)

I'm not convinced that this makes sense.  While there are still a lot of
touchpads around that need deceleration, modern ones tend to be larger and
more precise, so maybe we want to drop it at some point in the future?
Given that up to now, nobody else reported a problem with it, I'd prefer
to leave it in the set of "inofficial" configuration options.

Oops, the subject should be "Expose touchpad _decleration threshold_ in wsconsctl". Not 
sure why I wrote "sensitivity".
