* clutter/clutter-group.c:
        Make sure unrealizing a group also unrealizes children.

        * clutter/glx/clutter-stage-glx.c:
        Chain up to group unrealize to make sure textures get unrealized
        when changing context (see #718)

        * clutter/clutter-texture.c:
        Formatting cleanups
