If a tool wears out, it may have a pre-loaded pressure offset. In that case,
even when the tool is not physically in contact with the tablet surface it
will send pressure events.
Use automatic pressure offset detection, similar to what the X.Org wacom
driver does. On proximity-in, check the pressure and if the distance is above
50% of the range and the pressure is nonzero but below 20% of the range, use
that value as pressure offset.

If an x220 is updated to the touchpad firmware version 8.1, the touchpad
suffers from the same issues as the x230 and needs custom acceleration code.
Unfortunately we cannot detect this otherwise, so it is left to the user as a
custom hwdb setting.

The file is already larger than 4k, so we ended up truncating the file for the
tests. This went unnoticed until recent additions that ended up truncating it
halfway through an assignment.

(cherry picked from commit 9d96286a44)
Once we trigger diagonal scrolling, the device's scroll direction is set as
horiz+vert. From then on, both axes will be set on every subsequent scroll
event, even when the actual delta for an axis is 0.
This causes continuous scroll stop events in clients that care about these
things.

force distance to 0.

If the test is filtered out and we never run it generates a false positive.
Though it isn't listed in the "Checks" summary this is a bit hard to tell when
you're running >700 tests.

These aren't real button events and they are handled elsewhere, either through
proper touch events on touchscreen or through custom handling in the touchpad
