Now that ClutterActor has a default paint volume, subclasses may wish
to retrieve it without chaining up to the parent's implementation of
the get_paint_volume() function.
The get_default_paint_volume() returns a ClutterPaintVolume pointer
to the paint volume as computed by the default implementation of the
get_paint_volume() virtual function; it can only be used immediately,
as it's not guaranteed to survive across multiple frames.
Creating PaintVolume instances is not possible, and it's not recommended
anyway. It is, though, necessary to union paint volumes, especially with
2D boxes, in some cases.
Clutter should provide a simple convenience function that allows
unioning volumes to boxes in a moderately efficient way.

It should be possible to adapt the abicheck.sh script so that it
actually tests the ABI of libclutter-1.0.so taking into account
the backends that were compiled into Clutter, and avoid expected
failures if Clutter was not built with a specific backend.

We cannot deprecate ClutterAlpha yet. We cannot also implement
ClutterAlpha in terms of ClutterTimeline, because multiple Alpha
instances can be attached to the same Timeline. So we can start
with a "soft" deprecation: just a warning in the documentation
stating that ClutterAlpha will be deprecated, and removed, in the
future, and that newly-written code should use ClutterTimeline
instead.
We can use ClutterTimeline and its progress mode inside
ClutterAnimation; obviously, we have to maintain the invariants because
of the ClutterAnimation:alpha property, but if all you set is the :mode
property using one of the Clutter animation modes then we can skip the
ClutterAlpha entirely.
Instead of having the easing functions be dependent of ClutterAlpha, and
static to the clutter-alpha.c source file, we should make them generic
and move them to their own internal header and source files. This will
allow to re-use them in the near future.
Since Cogl has started restricting what cogl 1.x api is exposed when
COGL_ENABLE_EXPERIMENTAL_2_0_API is defined and since we build all
Clutter internals with COGL_ENABLE_EXPERIMENTAL_2_0_API defined this
patch makes a first pass at reducing our internal use of the Cogl 1.x
api.
The most notable api that's no longer exposed to us internally is
the cogl_material_ api so this switches all Clutter internals to use the
cogl_pipeline_ api instead. This patch also makes quite a bit of
progress removing internal uses of CoglHandle although there is still
more to go.
The experimental cogl_texture_pixmap_x11_new() api was recently changed
to take an explicit context argument and return a GError on failures.
This updates Clutter's use of the api accordingly.
We were only exposing clutter_backend_get_cogl_context() if
COGL_ENABLE_EXPERIMENTAL_2_0_API had been defined but the CoglContext
api is also available if COGL_ENABLE_EXPERIMENTAL_API has been defined.
As it was it meant that code opting into the experimental Cogl api
but not limiting to the 2.0 only api would have to #define
COGL_ENABLE_EXPERIMENTAL_2_0_API before including clutter.h but make
sure it wasn't defined when including cogl.h which was particularly
awkward.
Recently the cogl_framebuffer_swap_* apis were moved into the
cogl_onscreen_* namespace since only CoglOnscreen framebuffers can be
double buffered. This renames all uses of the cogl_framebuffer_swap_*
apis in Clutter.
The experimental cogl_pipeline_new() api was recently changed so it
explicitly takes a CoglContext. This updates all calls to
cogl_pipeline_new() in clutter accordingly.
ATK_ROLE_CANVAS is not a suitable role, as the user (in general) can't
draw on the Stage. CallyStage implements AtkWindow, so the proper role
is ATK_ROLE_WINDOW
Removing atkcomponent, focus_tracker, etc. Emitting focus state change
from the stage. Now things are more simple, and stop to use some
of the soon-to-be-deprecated signals on ATK.
It should be possible to do:
clutter_stage_set_fullscreen (stage, TRUE);
clutter_actor_show (stage);
and have the stage be full screen as soon as it is shown.
Currently, we need to call clutter_actor_realize() prior to calling
set_fullscreen(), otherwise the backing X window will not be set,
and ClutterStageX11 will silently discard the change.
If set_fullscreen() was called prior to realization, ClutterStageX11
should delay setting the fullscreen hint until the realize() chain
has been successfully executed.

If you execute the following sequence :
stage = clutter_stage_new ();
clutter_actor_set_size (stage, 1280, 800);
clutter_actor_realize (stage);
Then you end up creating an onscreen buffer of size 1280x800 but
ClutterStageX11 storing the stage size at 640x480.
This patch resync the 2 implementation by using the ClutterStage's
size in both classes when realizing.

Unconditionally creating CoglPipeline and CoglSnippets inside the class
initialization functions does not seem to be enough when dealing with
headless builds.
Our last resort is to lazily create the base pipeline the first time we
try to copy it, during the instance initialization.
