00b733a85a clutter-effect: Add clutter_effect_queue_rerun
This adds a new public function to queue a rerun of an effect. If
nothing else queues a redraw then when the effect's actor is painted
the effect will be run without the CLUTTER_EFFECT_RUN_ACTOR_DIRTY
flag. This allows parametrised offscreen effects to report that they
need to redraw the image without having to redraw the underlying
actor. This will be used to implement the 'transparency' effect of
ClutterActor.

If multiple redraws are queued with different effects then redrawing
is started from the one that occurs last in the list of effects.

Internally the function is a wrapper around the new function
_clutter_actor_queue_redraw_full. This is intended to be the sole
point of code for queuing redraws on an actor. It has parameters for
the clip and the effect. The other two existing functions to queue a
redraw (one with a clip and one without) now wrap around this function
by passing a NULL effect.

c3aa4d24bf clutter-effect: Add a 'run' virtual
This adds a new virtual to ClutterEffect which is intended to be a
more flexible replacement for the pre and post_paint functions. The
implementation of a run virtual would look something like this:

void
effect_run (ClutterEffect *effect,
            ClutterEffectRunFlags flags)
{
  /* Set up state */
  /* ... */

  /* Chain to the next item in the paint sequence */
  clutter_actor_continue_paint (priv->actor);

  /* Clean up state */
  /* ... */
}

ClutterActor now just calls this virtual instead of the pre_paint and
post_paint functions. It keeps track of the next effect in the list so
that it knows what to do when clutter_actor_continue_paint is
called. clutter_actor_continue_paint is a new function added just for
implementing effects.

The default implementation of the run virtual just calls pre_paint and
post_paint so that existing effects will continue to work.

An effect is allowed to conditionally skip calling
clutter_actor_continue_paint(). This is useful to implement effects
that cache the image of an actor. The flags parameter can be used to
determine if the actor is dirty since the last paint. ClutterActor
sets this flag whenever propagated_one_redraw is TRUE which means that
a redraw for this actor or one of its children was queued.

0be73bf401 effect: Queue a redraw on :enabled changes
ClutterEffect should queue a redraw if the :enabled property of its
parent class ClutterActorMeta changes.

3540d222e1 paint volumes: another pass at the design
This is a fairly extensive second pass at exposing paint volumes for
actors.

The API has changed to allow clutter_actor_get_paint_volume to fail
since there are times - such as when an actor isn't a descendent of the
stage - when the volume can't be determined. Another example is when
something has connected to the "paint" signal of the actor and we simply
have no way of knowing what might be drawn in that handler.

The API has also be changed to return a const ClutterPaintVolume pointer
(transfer none) so we can avoid having to dynamically allocate the
volumes in the most common/performance critical code paths. Profiling was
showing the slice allocation of volumes taking about 1% of an apps time,
for some fairly basic tests. Most volumes can now simply be allocated on
the stack; for clutter_actor_get_paint_volume we return a pointer to
&priv->paint_volume and if we need a more dynamic allocation there is
now a _clutter_stage_paint_volume_stack_allocate() mechanism which lets
us allocate data which expires at the start of the next frame.

The API has been extended to make it easier to implement
get_paint_volume for containers by using
clutter_actor_get_transformed_paint_volume and
clutter_paint_volume_union. The first allows you to query the paint
volume of a child but transformed into parent actor coordinates. The
second lets you combine volumes together so you can union all the
volumes for a container's children and report that as the container's
own volume.

The representation of paint volumes has been updated to consider that
2D actors are the most common.

The effect apis, clutter-texture and clutter-group have been update
accordingly.

25abdf09b7 effect: Allow any effect to override the paint volume
An Effect implementation might override the paint volume of the actor to
which it is applied to. The get_paint_volume() virtual function should
be added to the Effect class vtable so that any effect can get the
current paint volume and update it.

The clutter_actor_get_paint_volume() function becomes context aware, and
does the right thing if called from within a ClutterEffect pre_paint()
or post_paint() implementation, by allowing all effects in the chain up
to the caller to modify the paint volume.

a86f1b45bb Add the ClutterEffect abstract class
ClutterEffect is an abstract class that should be used to apply effects
on generic actors.

The ClutterEffect class just defines what an effect should implement; it
could be defined as an interface, but we might want to add some default
behavior dependent on the internal state at a later point.

The effect API applies to any actor, so we need to provide a way to
assign an effect to an actor, and let ClutterActor call the Effect
methods during the paint sequence.

Once an effect is attached to an actor we will perform the paint in this
order:

  • Effect::pre_paint()
  • Actor::paint signal emission
  • Effect::post_paint()

Since an effect might collide with the Shader class, we either allow a
shader or an effect for the time being.
