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.

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

(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.

At least on the t440, this is enough to trigger correct detection between
pinch and scroll 90% of the time. Since scrolling is significantly more
prevalent than gesturing, erring on the side of scrolling at the cost of
misdetecting some gestures is acceptable.

Behavior for axis events in the same event frame as the BTN_TOUCH is to
always send axis events before any tip state.
Behavior for button events in the same event frame as the BTN_TOUCH is to
order button events to happen when the tip is in proximity, i.e. after the tip
event on tip down and before the tip event on tip up.

The Asus RoG Gladius exposes two event nodes, one mouse, one keyboard. The
keyboard node has REL_X/Y and REL_HWHEEL on top of the various key bits and
ABS_VOLUME.
The keyboard node does not have BTN_* set, udev tags this device as a
keyboard only, not as a pointer but we still initialize the pointer caps for
it because of the wheel.
When moving this mouse, some deltas (ca "1 in every 20") are sent through the
keyboard node, causing a crash because we never initialized pointer
acceleration.

The quartett of new config functions is:
libinput_device_config_accel_get_profiles
libinput_device_config_accel_get_profile
libinput_device_config_accel_set_profile
libinput_device_config_accel_get_default_profile
The profile defines how the pointer acceleration works, from a very high-level
perspective. Two profiles are on offer, "adaptive", the standard one we have
used so far and "flat" which is a simple multiplier of input deltas and
provides 1:1 mapping of device movement vs pointer movement.
The speed setting is on top of the profile, a speed of 0 (default) is the
equivalent to "no pointer acceleration". This is popular among gamers and
users of switchable-dpi mice.
The flat profile unnormalizes the deltas, i.e. you get what the device does
and any device below 800dpi will feel excruciatingly slow. The speed range
[-1, 1] maps into 0-200% of the speed. At 200%, a delta of 1 is translated
into a 2 pixel movement, anything higher makes it rather pointless.
The flat profile is currently available for all pointer devices but touchpads.

If a caller has a reference to a device group when the context is destroyed,
the memory for the group is never released. Calling
libinput_device_group_unref() will release it and there are no side-effects
since the group has no back-references. It's inconsistent with the rest of
libinput though - all other resources get released on libinput_unref().

The following sequence currently generates a right-button event:
finger 1 down
finger 2 down
finger 1 up
finger 2 held down
This is easily triggered with short scroll events. There are two issues here:
first is that the tapping code elsewhere treats any tap with a second finger
down as a left-button tap, not a right button one. So if anything, we should
generate a left button click here, not a right button click.
Arguably, generating a button click here is wrong though, it's not a very well
defined sequence and relatively difficult to trigger intentionally. So the
best solution here is to simply ignore the release event and move straight
back to state HOLD - unless the second finger is released within the timeout.
If the finger is set down again during the timeout, we move straight to
TOUCH_2_HOLD - this could eventually be interpreted as a tap, but not for now.
