Big rework of the actor management semantics: now ClutterActor
objects behave like GtkObjects - that is they have an initial
"floating" reference that gets "sunk" when they are added to
a ClutterGroup. This makes a group responsible of de-allocating
each actor inside it, so you just have to destroy the group to
get every child actor destroyed. Also, now you can do:
clutter_group_add (group, clutter_video_texture_new ());
without having to care about reference counting and explicit
unreffing.
* clutter/clutter-private.h: Add private flags setter and
getter macros.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Clean up; inherit from GInitiallyUnowned;
add a "visible" property; add the "destroy", "show" and "hide"
signals to ClutterActorClass.
(clutter_actor_show), (clutter_actor_hide): Refactor a bit; emit
the "show" and "hide" signals.
(clutter_actor_set_property), (clutter_actor_get_property),
(clutter_actor_class_init): Implement the "visible" property; add
signals.
(clutter_actor_finalize): Do not leak the actor's name, if it is
set.
(clutter_actor_dispose): Emit the "destroy" signal here.
(clutter_actor_init): Sink the initial floating flag if needed.
(clutter_actor_destroy): Add a function to explicitely destroy
a ClutterActor.
(clutter_actor_set_parent), (clutter_actor_get_parent),
(clutter_actor_unparent): Make set_parent require a valid parent;
add unparent; check on get_parent; ref_sink the actor when
setting its parent and unref it when unsetting it. Probably we'll
need a function that does reparenting as unparent+set_parent in
a single shot.
* clutter/clutter-group.h:
* clutter/clutter-group.c (clutter_group_dispose),
(clutter_group_finalize), (clutter_group_add),
(clutter_group_remove): Make the group destroy its children when
disposing it; clean up, and use the newly-available
clutter_actor_unparent().
* clutter/clutter-stage.h:
* clutter/clutter-stage.c (clutter_stage_init): ClutterStage is
a top-level actor; clean up.
* clutter/clutter-video-texture.h:
* clutter/clutter-video-texture.c: Clean up.
* examples/super-oh.c:
* examples/test.c:
* examples/video-player.c:
* examples/test-text.c:
* examples/video-cube.c: Remove the g_object_unref() call, as the
ClutterStage object is destroyed on clutter_main_quit().

actor: Add internal child flag
ClutterActor checks, when destroying and reparenting, if the parent
actor implements the Container interface, and automatically calls the
remove() method to perform a clean removal.
Actors implementing Container, though, might have internal children;
that is, children that are not added through the Container API. It is
already possible to iterate through them using the Container API to
avoid breaking invariants - but calling clutter_actor_destroy() on
these children (even from the Container implementation, and thus outside
of Clutter's control) will either lead to leaks or to segmentation
faults.
Clutter needs a way to distinguish a clutter_actor_set_parent() done on
an internal child from one done on a "public" child; for this reason, a
push/pop pair of functions should be available to Actor implementations
to mark the section where they wish to add internal children:
➔ clutter_actor_push_internal ();
...
clutter_actor_set_parent (child1, parent);
clutter_actor_set_parent (child2, parent);
...
➔ clutter_actor_pop_internal ();
The set_parent() call will automatically set the newly added
INTERNAL_CHILD private flag on each child, and both
clutter_actor_destroy() and clutter_actor_unparent() will check for the
flag before deciding whether to call the Container's remove method.

* clutter-color.h:
* clutter-color.c: Reimplement ClutterColor as a boxed type;
add convenience API for color handling, like: add, subtract,
shade, HSL color-space conversion, packing and unpacking.
* clutter-private.h: Update ClutterMainContext, and export the
main context pointer here.
* clutter-rectangle.h:
* clutter-rectangle.c: Update the color-related code; make
clutter_rectangle_new() and empty constructor and provide
clutter_rectangle_new_with_color(); provide color setter
and getter API.
* clutter-label.h:
* clutter-label.c: Rename the "font" property to "font-name";
update the color-related code to the new ClutterColor object;
rename clutter_label_new() to clutter_label_new_with_text(),
and add setters and getters for the properties.
* clutter-marshal.list: Add VOID:OBJECT and VOID:BOXED marshallers
generators.
* clutter-stage.h:
* clutter-stage.c: Rework the API: provide a default constructor
for a singleton object, named clutter_stage_get_default(), which
supercedes the clutter_stage() function in clutter-main; provide
new events: button-press-event, button-release-event,
key-press-event and key-release-event; update the color-related
code;
(clutter_stage_snapshot): Allow negative width and height when
taking a snapshot (meaning: use full width/height).
(clutter_stage_get_element_at_pos): Rename clutter_stage_pick().
* clutter-element.c (clutter_element_paint): Clean up the
stage and color related code.
* clutter-event.h:
* clutter-event.c: Add generic ClutterAnyEvent type; add
clutter_event_new(), clutter_event_copy() and clutter_event_free();
make ClutterEvent a boxed type.
* clutter-main.h:
* clutter-main.c: Remove clutter_stage(); add clutter_main_quit(),
for cleanly quitting from clutter_main(); add multiple mainloops
support; allocate the ClutterCntx instead of adding it to the
stack; re-work the ClutterEvent dispatching.
* clutter-group.c (clutter_group_add), (clutter_group_remove): Keep
a reference on the element when added to a ClutterGroup.
* examples/rects.py
* examples/test.c:
* examples/test-text.c:
* examples/video-cube.c:
* examples/super-oh.c:

Big rework of the actor management semantics: now ClutterActor
objects behave like GtkObjects - that is they have an initial
"floating" reference that gets "sunk" when they are added to
a ClutterGroup. This makes a group responsible of de-allocating
each actor inside it, so you just have to destroy the group to
get every child actor destroyed. Also, now you can do:
clutter_group_add (group, clutter_video_texture_new ());
without having to care about reference counting and explicit
unreffing.
* clutter/clutter-private.h: Add private flags setter and
getter macros.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Clean up; inherit from GInitiallyUnowned;
add a "visible" property; add the "destroy", "show" and "hide"
signals to ClutterActorClass.
(clutter_actor_show), (clutter_actor_hide): Refactor a bit; emit
the "show" and "hide" signals.
(clutter_actor_set_property), (clutter_actor_get_property),
(clutter_actor_class_init): Implement the "visible" property; add
signals.
(clutter_actor_finalize): Do not leak the actor's name, if it is
set.
(clutter_actor_dispose): Emit the "destroy" signal here.
(clutter_actor_init): Sink the initial floating flag if needed.
(clutter_actor_destroy): Add a function to explicitely destroy
a ClutterActor.
(clutter_actor_set_parent), (clutter_actor_get_parent),
(clutter_actor_unparent): Make set_parent require a valid parent;
add unparent; check on get_parent; ref_sink the actor when
setting its parent and unref it when unsetting it. Probably we'll
need a function that does reparenting as unparent+set_parent in
a single shot.
* clutter/clutter-group.h:
* clutter/clutter-group.c (clutter_group_dispose),
(clutter_group_finalize), (clutter_group_add),
(clutter_group_remove): Make the group destroy its children when
disposing it; clean up, and use the newly-available
clutter_actor_unparent().
* clutter/clutter-stage.h:
* clutter/clutter-stage.c (clutter_stage_init): ClutterStage is
a top-level actor; clean up.
* clutter/clutter-video-texture.h:
* clutter/clutter-video-texture.c: Clean up.
* examples/super-oh.c:
* examples/test.c:
* examples/video-player.c:
* examples/test-text.c:
* examples/video-cube.c: Remove the g_object_unref() call, as the
ClutterStage object is destroyed on clutter_main_quit().
