commit 9db1b53bf097d88491b09257f25e23bad4a6a6d1
Author: Giovanni Campagna <gcampagna src gnome org>
Date: Fri Aug 26 03:09:18 2011 +0200
Add a new GDK backend
This commit introduces a new flavour for Clutter, that uses GDK
for handling all window system specific interactions (except for
creating the cogl context, as cogl does not know about GDK), including
in particular events. This is not compatible with the X11 (glx)
flavour, and this is reflected by the different soname (libclutter-gdk-1.0.so),
as all X11 specific functions and classes are not available. If you
wish to be compatible, you should check for CLUTTER_WINDOWING_X11.
Other than that, this backend should be on feature parity with X11,
including XInput 2, XSettings and EMWH (with much, much less code)
