Mice with high-resolution support can generate deltas when the finger is
put on the wheel or when the user tries to click the wheel.
To avoid sending involuntary scroll events, add an extra state the the
wheel state machine to accumulate scroll deltas.
While the accumulated scroll is lower than a certain threshold, ignore
them until the threshold is reached.
Since no finish event is sent by the mouse, reset the state machine
after a period of scroll inactivity.

Before hold gestures where implemented, when a thumb was detected it
was enough to reset the state machine.
However, now it is possible to detect a thumb while a hold gesture is
in course.
Cancel any ongoing gesture when a thumb is detected to avoid dropping
the gesture end event.

Some devices might announce support for high-resolution scroll wheel
by enabling REL_WHEEL_HI_RES and/or REL_HWHEEL_HI_RES but never send
a high-resolution scroll event.
When the first low-resolution scroll event is received without any
previous high-resolution event, print a kernel bug warning and start
emulating high-resolution scroll events.

GTK handles LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS as
GDK_SCROLL_SMOOTH, the same event type that is used to handle
LIBINPUT_EVENT_POINTER_SCROLL_FINGER.
Because Mutter and other compositors, like wlroots based compositors,
translate libinput terminating event to axis_stop instead of doing their
own emulation, if libinput stops sending terminating events, it will
cause client bugs.
Since libinput always sends the terminating event for trackpoints and
button scrolling and there are even tests in place to check for them,
update the documentation to guarantee the terminating scroll sequence.

It's been a while since we really could do something about those jumps,
so let's assume most of these are informative and not a bug in libinput.
For that let's not spam the user's journal and ratelimit it to a handful
a day.
Per day because that increases the chance of an error being present in
the recent logs if the user does search for it.

If a touchpad is removed before its dwt-paired keyboard, we're leaking
the keyboard struct. Fix this by cleaning up properly when our device is
removed.
This is the cause of many failed tests in the udev backend tests during
the CI valgrind run. Because we're testing the udev backend it will add
any devices created by tests run in parallel, some of which are keyboard
devices. Depening on the test completions, the keyboards may or may not
get removed before this device.

When the kernel doesn't support a touchpad, the device is handled as a
generic mouse named "ImPS/2 Generic Wheel Mouse".
Taps are handled as button clicks and the button debouncing code makes
it difficult to double click.
Add a quirk to disable button debouncing for this devices.

Starting with kernel v5.0 two new axes are available for high-resolution wheel
scrolling: REL_WHEEL_HI_RES and REL_HWHEEL_HI_RES. Both axes send data in
fractions of 120 where each multiple of 120 amounts to one logical scroll
event. Fractions of 120 indicate a wheel movement less than one detent.
This commit adds a new API for scroll events. Three new event types that encode
the axis source in the event type name and a new API to get a normalized-to-120
value that also used by Windows and the kernel (each multiple of 120 represents
a logical scroll click).
This addresses a main shortcoming with the existing API - it was unreliable to
calculate the click angle based on the axis value+discrete events and thus any
caller using the axis value alone would be left with some ambiguity. With the
v120 API it's now possible to (usually) calculate the click angle, but more
importantly it provides the simplest hw-independent way of scrolling by a
click or a fraction of a click.
A new event type is required, the only way to integrate the v120 value
otherwise was to start sending events with a discrete value of 0. This
would break existing xf86-input-libinput (divide by zero, fixed in 0.28.2) and
weston (general confusion). mutter, kwin are unaffected.
With the new API, the old POINTER_AXIS event are deprecated - callers should use
the new API where available and discard any POINTER_AXIS events.
Notable: REL_WHEEL/REL_HWHEEL are emulated by the kernel but there's no
guarantee that they'll come every accumulated 120 values, e.g. Logitech mice
often send events that don't add up to 120 per detent.
We use the kernel's wheel click emulation instead of doing our own.
libinput guarantees high-resolution events even on pre-5.0 kernels.

Set multiplier for T470 to 0.4, same as for T480.
Trackpoint behavior on T470 was good before 1.9.0 (more precisely,
before the commit 87b568) when a new trackpoint acceleration algorithm
was introduced instead of the traditional linear filter. Since then
it is too sensitive and seems impossible to fine-tune using hw settings
or libinput accel speed setting.
With multiplier set to 0.4 it is as good (or better) as in 1.8.4.
Sensitivity feels the same as in 1.8.4 with the same hw settings for
speed and sensitivity.
