Adds new properties and xorg.conf entries for setting the scroll acceleration
function's points and step.
The new xorg.conf entries are AccelPointsScroll, AccelStepScroll.
Adds new properties and xorg.conf entries for setting the acceleration
function's points and step.
`AccelProfile` option can now accept `custom` value.
Add 4 new options which only apply when `AccelProfile` is `custom`:
- Add `AccelPointsFallback` option for setting the points of the
Fallback acceleration function. Points values are represented by a
space-separated list, e.g. "0.0 1.0 2.4 2.5".
- Add `AccelStepFallback` option for setting the step of the Fallback
acceleration function. When a step of 0.0 is provided,
libinput default Fallback acceleration function is used.
- Add `AccelPointsMotion` and `AccelStepMotion` options, which are
equivalent to `AccelPointsFallback` and `AccelStepFallback` options,
but apply to the Motion acceleration function.
See libinput documentation for a detailed explanation of custom
pointer acceleration.
Missing else condition in PKG_CHECK_MODULES caused configure to bail out
where 2.4 wasn't available.

These don't change, iirc they exist because of some unixes having
different man pages but at this point really on Solaris is left and that
uses the same suffixes as everyone else.
And the __xservername__ is a leftover from the Xfree86 vs Xorg days - if
you're still running Xfree86, you're not using this driver.

xf86CheckStrOption returns the same value but doesn't mark it as used in

Starting on libinput 1.19 pointer axis events have been deprecated in
favor of their scroll equivalents, including support for high-resolution
wheel scroll.
While it is recommended to handle the new events, some applications
and/or frameworks might not be ready at the moment.
Provide an option to discard high-resolution wheel scroll events.

Where libinput supports high-resolution scroll events, the scroll source
is encoded in the event type.
Get the scroll source in xf86libinput_handle_event to facilitate the
migration.
Refactor, no functional changes.

This is just a number, to be used as divider and shouldn't have any effect in
correctly written clients. With the high-res scrolling coming up however, we
have a few devices where the dist cannot be expressed as an integer fraction
of 15, so let's up it to 120 because we know all hardware wheels have to be an
integer fraction of that that, thanks to Microsoft's API requirements.
For non-wheel scrolls we need to now map into the new range. Previously we
just passed the scroll events on from the touchpad/button scrolling, meaning a
vdist of 15 meant 15 "libinput pixels" of scrolling resulted in a logical
wheel click. Now that we have 120 as vdist, we need to times the input data by
8 to keep the same proportions.
See 39b0bb4585 for the previous revert.

To be used for touchpads and continuous (i.e. button-based scrolling).
libinput provides us with pixel data for finger-based and button-based
scrolling but the X server does support this - XI2.1 smooth scrolling is
merely centered around a logical scroll click (defined as "increment"), with
smooth scrolling being a fraction of that increment. For example, in the old
synaptics driver that value was in device-specific units and thus different
for every device.
The increment is a constant value set in the ScrollClass and cannot be changed
at device runtime. So we simply initialize with a random default (15, because
that works well for wheels) and then scale our pixel delta in to that range.
With the default value, a 15 pixel movement would result in a logical scroll
click, if the distance is set to 30 the users has to move 30 pixels to trigger
that scroll click. Pixel here being defined as the deltas that libinput
provides to us.
From the client's perspective nothing changes, the increment is still the
same.
Range checks are quite restrictive, this option is supposed to improve
usability, not as a workaround around other bugs.

If a touch input gets turned into a palm (by setting ABS_MT_TOOL_TYPE to
MT_TOOL_PALM), libinput will emit a cancel event instead of the normal
up event. The xorg wrapper needs to be able to handle a canceled touch
and lift it, otherwise these inputs will never get lifted and will stick
around forever.

Add a boolean option/property to enable/disable the scroll button lock. Where
enabled, the button can be clicked and released as opposed to having to be
held down.
