<pre>did you try it? because the basic approach right now is: delta * factor. What
the server does is delta * constant_deceleration * factor. So whether you add
this to the factor or later doesn't really matter.
... after checking the server sources again: it also appears to multiply the
velocity by the constant deceleration, so you'd need to apply this at the top
of the function accordingly.
libinput debug-gui is the best way to test these things, it can be run from the
builddir and the pointer is controlled by libinput only, so no need to restart
between recompilations.
