+ <title>Adapt to coordinate api changes</title>
+ <para>
+ A number of coordinate apis in GTK 3 had _double variants:
+ gdk_device_get_position(), gdk_device_get_surface_at_position(),
+ gdk_surface_get_device_position(). These have been changed to use
+ doubles, and the _double variants have been removed. Update your
+ code accordingly.
