[clutter/clutter-1.18] gesture: Clean up trigger edge accessors

[Emmanuele Bassi <ebassi src gnome org>]

commit 154ca6ef99655e1b8187176076b42ccd5cd01c52
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Thu Dec 5 11:49:53 2013 +0000

    gesture: Clean up trigger edge accessors
    
    Use G_GNUC_INTERNAL instead of the leading underscore, as we may make
    the accessor functions public at some point. Also, clean up the
    documentation.
