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.
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.
The Effects API and all related symbols have been superceded by
the newly added Animation API and clutter_actor_animate().
This commit removes the Effects implementation, the documentation
and the interactive test/example code.
* clutter.symbols: Add new ClutterBehaviourScale setters.
* clutter/clutter-behaviour-scale.[ch]: Split the scaling factors
on both axis. Add setters for all the behaviour properties.
* clutter/clutter-effect.h:
* clutter/clutter-effect.c (clutter_effect_scale): Split the
final scale factor to match the ClutterBehaviourScale changes. (#709)
* tests/test-actors.c:
* tests/test-effects.c:
* tests/test-rotate.c:
* tests/test-scale.c: Update after API change.
* clutter/clutter-effect.[ch]: Add clutter_effect_template_construct()
function, for language bindings that need to set the alpha function
but cannot call the clutter_effect_template_new() ctor themselves.
* clutter/clutter-effect.[ch]: Update the effects API to remove
the start value for most of them.
(clutter_effect_move): Make it a simple "move from current
position to new coordinates" effect.
(clutter_effect_path): Rename from clutter_effect_move().
(clutter_effect_rotate): Sync up with the new actor rotation API.

timeline changing its direction when reaching the last frame.

(clutter_effect_template_new_for_duration): Add a simple constructor
for implicitly creating a ClutterTimeline with a given duration.

* clutter/clutter-behaviour-rotate.h:
Split 'center' prop into 3 seperate props for each axis.
Use clutter_behaviour_actors_foreach() rather than
clutter_behaviour_get_actors() to avoid copying list.
Call fixed point rotation funcs internally.
* clutter/clutter-effect.c:
* clutter/clutter-effect.h:
Add new simple rotation based effect funcs.
Make ClutterEffectTemplate use a pointer to the private data to avoid
a type check each time it dereferences the ClutterEffectTemplatePrivate
structure pointer.
Clean up the header file for parsing purposes.
Add a description for the gtk-doc reference.
