commit f5a20ab65a3d03fb90c27b2fa1954d965f8ad768
Author: Carlos Garnacho <carlosg gnome org>
Date: Mon Dec 13 02:12:43 2010 +0100
Add gdk_event_[gs]et_source_device().
This function may be used to know the hardware device that triggered
an event, it could resort to the master device in the few cases there's
not a direct hardware device to relate to the event (i.e.: crossing events
due to grabs)
