8a8cc20d93 docs: Move ClutterAnimationMode's documentation
Given that ClutterAnimation is going to be deprecated, we should move
the ClutterAnimationMode enumeration to the ClutterTimeline section.

c500fc1844 Add ClutterTransitionGroup
The TransitionGroup class is a logical container for running multiple
transitions.

TransitionGroup is not a Score: it is a Transition that advances each
Transition it contains using the delta between frames, and ensures that
all transitions are in a consistent state; these transitions are not
advanced by the master clock.

388f818f41 timeline: Add more state accessors
It should be possible to ask a timeline what is its duration, taking

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.

13e3f9e5f1 Add an input device function to convert keycodes to evdev codes
This adds a virtual function to ClutterInputDevice to translate a
keycode from the hardware_keycode member of ClutterKeyEvent to an
evdev keycode. The function can fail so that input backends that don't
have a sensible way to translate to evdev keycodes can return FALSE.
There are implementations for evdev, wayland and X. The X
implementation assumes that the X server is using an evdev driver in
which case the hardware keycodes are the evdev codes plus 8.

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.

041ac40056 offscreen-effect: Add clutter_offscreen_effect_get_texture
Sometimes a subclass of ClutterOffscreenEffect wants to paint with a
completely custom material. In that case it is awkward to modify the
material returned owned by ClutterOffscreenEffect so it makes more
sense to just get the texture and manage its own material.

3996ae4348 actor: Add destroy_all_children()
There are times when we don't want to remove all children and count of

such as managed environments, where it's preferable to ensure that the

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.

While providing documentation on how to implement it using the

of the Pango API, was not worth it, and decided to expose the method we

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.

16ed7677e0 Adds wayland-surface actor for wayland compositors
This adds a --enable-wayland-compositor configure option which will add
support for a ClutterWaylandSurface actor which can be used to aid in
writing Wayland compositors using Clutter by providing a ClutterActor to
represent Wayland client surfaces.

Notably this configure option isn't tied into any particular backend
since conceptually the compositor support can be used in conjunction
with any clutter backend that has corresponding Cogl support.

07c6f96cb4 wayland: Updates client side wayland support
This updates Wayland support in line with upstream changes to the Wayland
API and protocol.

This update means we no longer use the Cogl stub winsys so a lot of code
that had to manually interact with EGL and implement a swap_buffers
mechanism could be removed and instead we now depend on Cogl to handle
those things for us.

This update also adds an input device manager consistent with other
clutter backends.

Note: to use the client side "wayland" clutter backend you need to have
built Cogl with --enable-wayland-egl-platform. If Cogl has been built
with support for multiple winsys backends then you should run
applications with COGL_RENDERER=EGL in the environment.
