* clutter/clutter-feature.h:
        * clutter/clutter-texture.c:
        * clutter/clutter-texture.h:
        * clutter/cogl/cogl.h:

        * clutter/cogl/gles/cogl.c:
        * tests/Makefile.am:
        * tests/test.fbo.c:
        Add initial support for FBO's in Clutter (OpenGL only so far).
        See new clutter_texture_new_from_actor()
        Initial implementation, needs work.

        * clutter/x11/clutter-stage-x11.c:
        (clutter_stage_x11_set_cursor_visible):
        Fall back to again not relying on xfixes to hide cursor. *sigh*

        * clutter/clutter-deprecated.h:
        Add clutter_group_find_child_by_id
