[PATCH weston 30/31] Add weston_compositor::input_init

Daniel Stone daniel at fooishbar.org
Wed May 30 08:32:08 PDT 2012


This function gets called after backend_init, so compositors can add
their input devices slightly later on in the process.  This gives us a
chance to set the default XKB rulesets, in particular.
