window: Export theme variant to X11

Browse Source 
The metacity theme format allows to use colors from the current
GTK+ theme in window decorations. Since GTK+ now gained support
for dark theme variants, window managers using that theme format
(metacity, mutter, compiz via gtk-window-decorator) should be able
to use colors from the correct variant; so in case a variant is
requested, export it in the _GTK_THEME_VARIANT property on
toplevel windows.

* gdk_x11_window_set_theme_variant:
* @window: a #GdkWindow

* GTK+ applications can request a dark theme variant. In order to
* make other applications - namely window managers using GTK+ for
* themeing - aware of this choice, GTK+ uses this function to
* export the requested theme variant as _GTK_THEME_VARIANT property
* on toplevel windows.
*
* Note that this property is automatically updated by GTK+, so this
* function should only be used by applications which do not use GTK+
* to create toplevel windows.

* Since: 3.2
