The recommended way to have libinput ignore specific devices so far was to
remove the ID_INPUT* properties from the device. That may also affect other
pieces of the stack that need access to this device.
For the niche case of a device that should only be ignored by libinput but
otherwise be treated normally by the system, we now support the
LIBINPUT_IGNORE_DEVICE property.
If the property is set to "0", it's equivalent to being unset. This gets
around some technical limitations in udev where unsetting a property is
impossible via a hwdb entry.

Some devices have worn-out switches or just cheap switches that trigger
multiple button events for each press. These can be identified by unfeasably
short time deltas between the release and the next press event. In the
recordings I've seen so far, that timeout is 8ms.
We have a two-stage behavior: by default, we do not delay any events but we
monitor timestamps. The first time a bouncing button is detected we switch to
debounce mode. From then on, release events are delayed slightly to check for
subsequent button events. If one occurs, the releas and press are filtered. If
none occurs, the release event is passed to the caller.

If a touch goes past the fixed pressure threshold it is labelled as a palm and
stays a palm. Default value is one that works well here on a T440 and is
virtually impossible to trigger by a normal finger or thumb. A udev property
is exposed so we can handle this in the udev hwdb and the new tool introduce a
few commits ago can help finding the palm detection threshold.
Unlike the other palm detection features, once a palm goes past the threshold
it remains a palm until the touch is released. This means palm overrides any
other palm detection features. For code simplicity, we don't combine the
states but merely check for pressure before and after the other palm detection
functions. If the pressure triggers, it will trigger before anything else. And
if something else is already active (e.g. edge where the pressure doesn't work
well) it will trigger as soon as the palm is released.
The palm threshold should thus be chosen with some room to spare between the
highest finger pressure.

`abs` has been deprecated, and shut down last month. [1]
`asp` replaces it, so rewrite the instructions to use this instead.
Also, add `--noextract` to the makepkg command, as there is no point
downloading and extracting the sources since they're not going to be
built here.

On some devices, X coordinate is not working well, like if it is swapped:
click on right, pointer appear on left and vice versa.
To sort this issue, coordinates should be reflected on Y axis:
- new X position is changed (width is subtracted by X position)
- Y is unchanged (it was wrongly set to X)
In landscape (or portrait) mode:
[ x ]
[ y ]
[ 1 ]
* =
[ -1 0 1 ] [ x' ] = -x + 0*y + 1*width
[ 0 1 0 ] [ y' ] = 0*x + 1*y + 0*height
[ 0 0 1 ] [ 1 ]
This was verified using this touch screen (usb="0eef:0001")

Easier to track if we leave the original files alone. Actual changes to the
doxygen style:
* indent <dd> blocks
* hide the navigation sub-items. Our current style expands the full navigation
menu but File-list, etc. is mostly useless and just wastes space.
* force some space below the main bar
* change the header sizes around a bit. Primary goal here: making <h1> smaller
than the title

This will allow switch devices known to libinput to be exposed. Currently,
this is SW_LID.
libinput also handles switch events internally, e.g. a laptop touchpad will
be disabled autmoatically when the lid is closed. This is transparent to
the caller, although the caller will also receive the event. See
https://bugs.freedesktop.org/show_bug.cgi?id=86223
This features is intended to be the main driver for the interface.

Let's take the default doxygen value but just add the https to it. In the

So far we've relied on the wacom kernel module to do touch arbitration for us
but that won't be the case in upcoming kernels. Implement touch arbitration in
userspace by pairing the two devices and suspending the touch device whenever
a tool comes into proximity.
In the future more sophisticated arbitration can be done (e.g. only touches
which are close to the pen) but let's burn that bridge when we have to cross
it.
Note that touch arbitration is "device suspend light", i.e. we leave the
device enabled and the fd is active. Tablet interactions are comparatively
short-lived, so closing the fd and asking logind for a new one every time the
pen changes proximity is suboptimal. Instead, we just keep a boolean around
and discard all events while it is set.
