2007-11-17 Emmanuele Bassi <ebassi@openedhand.com>
Optimise Atoms usage in the X11 and X11-based backends.
* clutter/x11/clutter-backend-x11.c:
(clutter_backend_x11_post_parse): Call XInternAtoms() here and
get all the atoms from X in one call.
* clutter/x11/clutter-backend-x11.h: Store all the atoms inside
the ClutterBackendX11 structure.
* clutter/x11/clutter-event-x11.c:
(xembed_send_message), (xembed_set_info),
(_clutter_backend_x11_events_init),
(set_user_time), (handle_wm_protocols_event),
(handle_xembed_event), (event_translate): Do not cache atoms
or call XInternAtom() directly, and use the atoms off the X11
backend structure instead.
* clutter/x11/clutter-stage-x11.c:
(send_wmspec_change_state), (clutter_stage_x11_set_wm_protocols),
(clutter_stage_x11_set_fullscreen),
(clutter_stage_x11_set_title): Ditto as above.
* clutter/x11/clutter-stage-x11.h: Update the set_wm_protocols()
method to take the X11 stage implementation.
* clutter/glx/clutter-stage-glx.c:
(clutter_stage_glx_realize): Update for the set_wm_protocols()
change.
* tests/test-project.c: (main): Test clutter_stage_set_title().
2007-11-17 Emmanuele Bassi <ebassi@openedhand.com>
* configure.ac: Depend on GLib >= 2.14 because of ClutterModel
