The custom acceleration profile allow the user to define custom
acceleration functions for each movement type per device, giving
full control over accelerations behavior at different speeds.
This commit introduces 2 movement types which corresponds to the
2 profiles currently in use by libinput.
regular filter is Motion type.
constant filter is Fallback type.
This allows possible expansion of new movement types for the
different devices.
The custom pointer acceleration profile gives the user full control over the
acceleration behavior at different speeds.
The user needs to provide a custom acceleration function f(x) where
the x-axis is the device speed and the y-axis is the pointer speed.
The user should take into account the native device dpi and screen dpi in
order to achieve the desired behavior/feel of the acceleration.
The custom acceleration function is defined using n points which are spaced
uniformly along the x-axis, starting from 0 and continuing in constant steps.
There by the points defining the custom function are:
(0 * step, f[0]), (1 * step, f[1]), ..., ((n-1) * step, f[n-1])
where f is a list of n unitless values defining the acceleration
factor for each velocity.
When a velocity value does not lie exactly on those points, a linear
interpolation of the two closest points will be calculated.
When a velocity value is greater than the max point defined, a linear
extrapolation of the two biggest points will be calculated.

Unlike in traditional touchpads, whose pressure value equals contact
size, on pressure pads pressure is a real physical axis.
We don't take advantage of the pressure information reported by
pressure pads yet, so we disable it to avoid errors.
Add a new model quirk for pressure pads instead of disabling
ABS_MT_PRESSURE and ABS_PRESSURE.

This switches the quirk from AttrEventCodeEnable/Disable to just
AttrEventCode with a +/- prefix for each entry.
This switches the quirk from AttrInputPropEnable/Disable to just
AttrInputProp with a +/- prefix for each entry.
Previously, both event codes and input props would only apply the
last-matching section entry for a device. Furthermore, an earlier Disable entry
would take precedence over a later Enable entry. For example, a set of
sections with these lines *should* enable left, right and middle:
[first]
AttrEventCodeEnable=BTN_LEFT;BTN_RIGHT;BTN_MIDDLE
[second]
AttrEventCodeDisable=BTN_RIGHT
[third]
AttrEventCodeEnable=BTN_LEFT;BTN_RIGHT;
Alas: the first line was effectively ignored (quirks only returned the
last-matching one, i.e. the one from "third"). And due to implementation
details in evdev.c, the Disable attribute was processed after Enable,
i.e. the device was enabled for left + right and then disabled for
right. As a result, the device only had BTN_LEFT enabled.
Fix this by changing the attribute to carry both enable/disable
information and merging the commands together.
Internally, all quirks matching a device are simply ref'd into an array
in the struct quirks. The applied value is simply the last entry in the
array corresponding to our quirk.
For AttrEventCode and AttrInputProp instead do this:
- switch them to a tuple with the code as first entry and a boolean
enable/disable as second entry
- if the struct quirk already has an entry for either, append the more
recent one to the existing entry (instead of creating a new entry in
the array). This way we have all entries that match and in-order of
precedence - i.e. we can process them left-to-right to end up
with the right state.

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.
Fix#668
Signed-off-by: José Expósito <jose.exposito89@gmail.com>
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.

According to the linker man page libraries are searched in the following paths:
LD_LIBRARY_PATH environment variable
Paths in the cache file /etc/ld.so.cache
/lib, /usr/lib, /lib64 and /usr/lib64
As we are not using LD_LIBRARY_PATH, we can rely on ldconfig as a fairly portable solution because it "creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf, and in the trusted directories (/lib and /usr/lib)".
