* 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
