bc914bb8a2 Move towards an alloc/init pair for base types
Instead of a single new() constructor that both allocates and
initializes, split the allocation and initialization into two separate
functions for types that are typically used on the stack, and rarely
allocated on the heap, like ClutterPoint and friends.

This is also applied retroactively to ClutterActorBox and ClutterVertex,
given that the same considerations on usage apply to them as well; we
can add a return value to clutter_actor_box_init() and
clutter_vertex_init() in an ABI-compatible way, so that
clutter_actor_box_new() and clutter_vertex_new() can be effectively
reimplemented as "init (alloc ())".

61f17e345a Add base geometric types
Clutter should provide some more basic geometric types - Point, Size,
Rect - so that we can use them in properties and accessors.

e2564dd265 Deprecate ClutterCairoTexture
The ClutterCanvas content implementation should be used instead, to
avoid stringing along the ClutterTexture API and implementation.

This change requires some minor surgery, as the deprecated section
already contains an header for the previously deprecated methods; plus,
we don't want to deprecate clutter_cairo_set_source_color(). This means
creating a new header to be used for Cairo-related API.

8904f7cbe4 paint-nodes: Make part of the API internal
At least for the time being, we only expose the parts of the API that we
want to use internally and for new, out-of-tree Content implementations.

The full PaintNode tree API will be made public in 1.12 once we branch
master.

4bd3583dbf actor: Add generic transition support
ClutterActor should be able to hold all transitions, even the ones that
have been explicitly created.

This will allow to add new transitions types in the future, like the
keyframe-based one, or the transition group.

388f818f41 timeline: Add more state accessors
It should be possible to ask a timeline what is its duration, taking
into account eventual repeats, and which repeat is the one currently
in progress.

These two functions allow writing animations that depend on the current
state of another timeline.

1511e588df actor: Add delay to the easing state
It should be possible to set up the delay of a transition, but since
we start the Transition instance before returning control to the caller,
we cannot use clutter_actor_get_transition() to do it without something
extra-awkward, like:

  transition = clutter_actor_get_transition (actor, "width");
  clutter_timeline_stop (transition);
  clutter_timeline_set_delay (transition, 1000);
  clutter_timeline_start (transition);

for each property involved. It's much easier to add a delay to the
easing state of an actor.

229607464b Improve repaint functions
It is sometimes useful to be able to have better control on when a
repaint function is called. Currently, all repaint functions are called
prior to the stages update phase of the frame processing.

We can introduce flags to represent the point in the frame update
process in which we wish Clutter called the repaint function.

As a bonus, we can also add a flag that causes adding a repaint function
to spin the master clock.

e4c948b150 actor: Add a method for computing the default paint volume
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.

6a09bf5b52 paint-volume: Add a union method for boxes
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.

3996ae4348 actor: Add destroy_all_children()
There are times when we don't want to remove all children and count of
the reference count to drop to 0 to ensure destruction; there are cases,
such as managed environments, where it's preferable to ensure that the
children of an actor get actually destroyed.

97feb06a6f timeline: Add repeat-count
Being able to easily set the number of repeats has been a request for
the animation framework for some time now. The usual way to implement
this is: connect to the ::completed signal, use a static counter, and
stop the timeline when the counter hits a specific spot.

In the same light as the :auto-reverse property, we can make it easier
to implement this common functionality by adding a :repeat-count
property that, when set, limits the amount of loops that a Timeline can
perform before stopping itself.

In fact, we can implement the :loop property in terms of the
:repeat-count property just by using a sentinel value mapping to
"infinity", and map loop=FALSE to repeat-count=0, and loop=TRUE to
repeat-count=-1.

7ba9774572 text: Add the coords_to_position() method
The reverse of position_to_coords().

While providing documentation on how to implement it using the
PangoLayout API, I realized that the verbosity of it all, plus the usage
of the Pango API, was not worth it, and decided to expose the method we
are using internally.

58ffcfb10e actor: Add ClutterActorIter
Iterating over children and ancestors of an actor is a relatively common
operation. Currently, you only have one option: start a for() loop, get
the first child of the actor, and advance to the next sibling for the
list of children; or start a for() loop and advance to the parent of the
actor.

These operations can be easily done through the ClutterActor API, but
they all require going through the public API, and performing multiple
type checks on the arguments.

Along with the DOM API, it would be nice to have an ancillary, utility
API that uses an iterator structure to hold the state, and can be
advanced in a loop.
