Code review comment for lp:~andreas-pokorny/mir/add-option-to-disable-acceleration

Oh, we need to check and verify that the libinput API is not misusing the word "acceleration" like others do. If they are using the word acceleration accurately, then curiously there is no option to change the pointer speed without also accelerating.

We need to check the libinput source and make sure their terminology is correct before we do the same.
