Subject: [PATCH] gdk: Allow disabling event retrieval
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Just like the other backends can disable the internal event handling,
and use clutter_<backend>_handle_event() to do the native → Clutter
event translation.
