|

*
|

|
* To be consistent with other clutter backends though we only associate the
|
||
|
* device manager with the backend when _clutter_events_wayland_init() is
|
||
|
* called in _clutter_backend_init_events(). This should still allow the
|

* runtime selection of an alternative input backend if desired and in that
|
||
|
* case the wayland device manager will be benign.
|

|
*
|

* FIXME: At some point we could perhaps collapse the
|
||
|
* _clutter_backend_post_parse(), and _clutter_backend_init_events()
|
||
|
* functions into one called something like _clutter_backend_init() which
|
||
|
* would allow the real backend to manage the precise order of
|

* initialization.
