This was a stopgap measure to support the Lenovo Carbon X1 3rd and the Lenovo
*50 series. These devices have the trackpoint buttons wired to the touchpad
and thus trackpoint events came from the touchpad device.
This was fixed in the kernel commit cdd9dc195916ef5644cfac079094c3c1d1616e4c,
the systemd hwdb to set this property was removed in 05304592457e01 so nothing
sets this property anymore. Drop it.

For touchscreens we always send raw touch events to the compositor, and the
compositor or application toolkits do gesture recognition. This makes sense
because on a touchscreen which window / widget the touches are over is
important context to know to interpret gestures.
On touchpads however we never send raw events since a touchpad is an absolute
device which primary function is to send pointer motion delta-s, so we always
need to do processing (and a lot of it) on the raw events.
Moreover there is nothing underneath the finger which influences how to
interpret gestures, and there is a lot of touchpad and libinput configuration
specific context necessary for gesture recognition. E.g. is this a clickpad,
and if so are softbuttons or clickfinger used? What is the size of the
softbuttons? Is this a true multi-touch touchpad or a semi multi-touch touchpad
which only gives us a bounding box enclosing the fingers? Etc.
So for touchpads it is better to do gesture processing in libinput, this commit
adds an initial implementation of a Gesture event API which only supports swipe
gestures, other gestures will be added later following the same model wrt,
having clear start and stop events and the number of fingers involved being
fixed once a gesture sequence starts.

Alps devices don't know if there is a physical middle button on the touchpad,
so they always report one.
Since a large number of touchpads only have two buttons, enable middle button
emulation by default. Those that really don't want it can play with
configuration options, everyone else has it working by default.
The hwdb entry uses "*Alps ..*" as name to also trigger the "litest Alps..."

To quote Bryce Harrington from [1]:
"MIT has released software under several slightly different licenses,

X.org now prefers the MIT Expat License as the standard (which,

libinput is a fork of weston and thus inherited the original license intent

Tagging a device should occur only once during configure. We do not
have devices that can be changed after they are configured, so there is no

The System76 Galago Ultra Pro is a rebranded Clevo W740SU with changed

possess smooth touchpads.
In the original bug report[1], a Galago Ultra Pro was returned to the
original DMI strings by flashing another firmware. This resulted in the
model identified as MODEL_SYSTEM76_CLEVO.
Since the actual manufacturer of the W740SU is Clevo and the CLEVO hwdb

S413, the model should be renamed to match.

keeping the same feeling as regular touchpads at high speed.
It still feels slower but it is usable at least

This way the unaccelerated deltas returned by libinput are correct.
To maintain the current behavior we slow down the input speed by the magic
factor and likewise the accelerated output speed. This produces virtually the
same accelerated deltas as the previous code.
The magic factor is applied to the default denominator for guessing a
resolution based on the touchpad diagonal. We can't really get around this
without having a resolution from the touchpad; meanwhile this produces
virtually the same coordinates before/after.

If a tool is in proximity when we init, send a proximity event immediately.
This is only partially reliable due to the current kernel behavior:
* if the tool comes into proximity when there is no evdev client, the device
won't send any events and must be lifted out-of-proximity first. Patch is in
the works, see https://patchwork.kernel.org/patch/5924611/
* before 3.19, if the tool was in proximity (with an evdev client attached),
but goes out of proximity and back in with no client connected, we get an
immediate proximity out event from the kernel once we connect to the device
and no further events after that.
See kernel commit b905811a49bcd6e6726ce5bbb591f57aaddfd3be
Otherwise, things work as expected. The above should be fixed in the kernel
anyway.
Note that this changes the order of events during a udev seat init, before we
had all DEVICE_ADDED events in a row, now the proximity event may be
interspersed.

Some devices require more than just flipping around the buttons, such as
tablets.
When it comes to devices like tablets, because the position of the palm rest is
on the right, the entire tablet has to be flipped around in order to be usable
by lefties. As such, this requires that we reverse the coordinates of the
tablets in addition to flipping the buttons on the tablet. As such, renaming
these functions so that they aren't specific to devices where only the buttons

For a caller to implement/provide kinetic scrolling ("inertial scrolling",
"fling scrolling"), it needs to know how the scrolling motion was implemented,
and what to expect in the future. Add this information to the pointer axis
event.
The three scroll sources we have are:
* wheels: scrolling is in discreet steps, you don't know when it ends, the
wheel will just stop sending events
* fingers: scrolling is continuous coordinate space, we know when it stops and
we can tell the caller
* continuous: scrolling is in continuous coordinate space but we may or may not
know when it stops. if scroll lock is used, the device may never technically
get out of scroll mode even if it doesn't send events at any given moment
Use case: trackpoint/trackball scroll emulation on button press
The stop event is now codified in the API documentation, so callers can use
that for kinetic scrolling. libinput does not implement kinetic scrolling
itself.
Not covered by this patch:
* The wheel event is currently defined as "typical mouse wheel step", this is
different to Qt where the step value is 1/8 of a degree. Some better
definition here may help.
* It is unclear how an absolute device would map into relative motion if the
device itself is not controlling absolute motion.
* For diagonal scrolling, the vertical/horizontal terminator events would come
in separately. The caller would have to deal with that somehow.
