Some older touchpad devices jitter a fair bit when a finger is resting on the
touchpad. That's why the hysteresis was introduced in the synaptics driver
back in 2011. However, the default value of the hysteresis in the synaptics
driver ended up being 0, even though the code looks like it's using a fraction
of the touchpad diagonal. When the hysteresis code was ported to libinput it
was eventually set to 0.5mm.
Turns out this is still too high and tiny finger motions are either
nonreactive or quite jumpy, making it hard to select small targets. Drop the
hysteresis by reducing its margin to 0. I'm leaving the code in place for now
because this will likely be needed for some devices.

patch is withdrawn, I just got recordings from a touchpad that needs it, so
I'll combine this patch with the one that keeps the behaviour for that
touchpad
I'm pretty sure that my alps semi-mt touchpad needs this too. Chances are
all semi-mt and single touch touchpads benefit from this ...

Hans
