Peter Hutterer 339f3dc979 Add a pointer acceleration API 
Only exposes one knob - speed, normalized to a [-1, 1] range with 0 being the
neutral "this is what we think is normal" speed. -1 and 1 reflect the
slowest/fastest reasonable speed on this device.

Note: with this API we commit to having any pointer accelerating as a true
gliding scale. We cannot map the [-1,1] range into a discrete set of steps
as we do not communicate to the caller whether a specific value has changed
the acceleration. Without that, a caller may assume that acceleration has
changed even when it is not visible to the user.

libinput

libinput is a library that handles input devices for display servers and other
applications that need to directly deal with input devices.

It provides device detection, device handling, input device event processing
and abstraction so minimize the amount of custom input code the user of
libinput need to provide the common set of functionality that users expect.

Input event processing includes scaling touch coordinates, generating
pointer events from touchpads, pointer acceleration, etc.

libinput originates from weston, the Wayland reference compositor.
