libinput (Input device library)

libinput is a library to handle input devices in Wayland compositors
and to provide a generic X.Org input driver.

It provides device detection, device handling, input  device  event
processing and abstraction so minimize the amount of  custom  input
code compositors 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.
