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.

A lot of the example code in the cookbook and the API reference still
uses the default stage — sometimes as if it were a non-default one,

a09bbffd92 Implement multi-backend support
The Clutter backend split is opaque enough that should allow us to just
build all possible backends inside the same shared object, and select
the wanted backend at initialization time.

This requires some work in the build system, as well as the
initialization code, to remove duplicate functions that might cause
conflicts at build and link time. We also need to defer all the checks
of the internal state of the platform-specific API to run-time type
checks.

7f8838d7cc cairo-texture: Add the :auto-resize property
Keeping the backing Cairo surface of a CairoTexture canvas in sync with
the actor's allocation is tedious and prone to mistakes. We can
definitely do better by simply exposing a property that does the surface
resize and invalidation automagically on ::allocate.

2f445682b1 cairo-texture: Use signal-based drawing
The current "create context/draw/destroy context" pattern presents
various problems. The first issue is that it defers memory management to
the caller of the create() or create_region() methods, which makes
bookkeeping of the cairo_t* harder for language bindings and third party
libraries. The second issue is that, while it's easier for
draw-and-forget texturs, this API is needlessly complicated for contents
that have to change programmatically - and it introduces constraints
like calling the drawing code explicitly after a surface resize (e.g.
inside an allocate() implementation).

By using a signal-based approach we can make the CairoTexture actor
behave like other actors, and like other libraries using Cairo as their
2D drawing API.

The semantics of the newly-introduced ::draw signal are the same as the
one used by GTK+:

  - the signal is emitted on invalidation;
  - the cairo_t* context is owned by the actor;
  - it is safe to have multiple callbacks attached to the same
    signal, to allow composition;
  - the cairo_t* is already clipped to the invalidated area, so
    that Cairo can discard geometry immediately before we upload
    the texture data.

There are possible future improvements, like coalescing multiple
invalidations inside regions, and performing clipped draws during
the paint cycle; we could even perform clipped redraws if we know the
extent of the invalidated area.

a72237b876 clutter-stage: Add clutter_stage_get_redraw_clip_bounds
This adds a public function to get the bounds of the current clipped
redraw on a stage. This should only be called while the stage is being
painted. The function diverts to a virtual function on the
ClutterStageWindow implementation. If the function isn't implemented
or it returns FALSE then the entire stage is reported. The clip bounds
are in integer pixel coordinates in the stage's coordinate space.

The recommended command to check for differences from master to the

of the remote master because the range is backwards. This patch

2b81d90dd7 Eliminate G_CONST_RETURN
The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy.

We always used it to conform to the platform, at least for public-facing
API.

At first I assumed it has something to do with brain-damaged compilers
or with weird platforms where const was not really supported; sadly,
it's something much, much worse: it's a define that can be toggled at
compile-time to remove const from the signature of public API. This is a
truly terrifying feature that I assume was added in the past century,
and whose inception clearly had something to do with massive doses of
absynthe and opium — because any other explanation would make the
existence of such a feature even worse than assuming drugs had anything
to do with it.

Anyway, and pleasing the gods, this dubious feature is being
removed/deprecated in GLib; see bug:

  https://bugzilla.gnome.org/show_bug.cgi?id=644611

Before deprecation, though, we should just remove its usage from the
whole API. We should especially remove its usage from Cally's internals,
since there it never made sense in the first place.

701440efd8 clutter-actor: Add a 'has_overlaps' virtual
This adds a virtual to ClutterActor so that an actor subclass can
report whether it has overlapping primitives. ClutterActor uses this
to determine whether it needs to use ClutterFlattenEffect to implement
the opacity property. The default implementation of the virtual
returns TRUE which means that most actors will end up being redirected
offscreen when the opacity != 255. ClutterTexture and ClutterRectangle
override this to return FALSE because they should never need to be
redirected. ClutterClone overrides it to divert to the source.

The values for the ClutterOffscreenRedirect enum have changed to:

AUTOMATIC_FOR_OPACITY

 The actor will only be redirected if has_overlaps returns TRUE and
 the opacity is < 255

ALWAYS_FOR_OPACITY

 The actor will always be redirected if the opacity < 255 regardless
 of the return value of has_overlaps

ALWAYS

 The actor will always be redirected offscreen.

This means that the property can't be used to prevent the actor from
being redirected but only to increase the likelihood that it will be
redirected.

ClutterActor now adds and removes the flatten effect depending on
whether flattening is needed directly in clutter_actor_paint(). There
are new internal versions of add/remove_effect that don't queue a
redraw. This means that ClutterFlattenEffect is now just a no-op
subclass of ClutterOffscreen. It is only needed because
ClutterOffscreen is abstract. Removing the effect also makes it so
that the cached image will be freed as soon as an actor is repainted
without being flattened.

7f78237ee5 clutter-actor: Add an 'offscreen-redirect' property
This adds a property which can be used to redirect the actor through
an FBO before painting so that it becomes flattened in an image. The
image can be used as a cache to avoid having to repaint the actor if
something unrelated in the scene changes. It can also be used to
implement correct opacity even if the actor has overlapping
primitives. The property is an enum that takes three values:

CLUTTER_OFFSCREEN_REDIRECT_NEVER: The default behaviour which is to
  never flatten the actor.

CLUTTER_OFFSCREEN_REDIRECT_ALWAYS: The actor is always redirected
  through an FBO.

CLUTTER_OFFSCREEN_REDIRECT_ONLY_FOR_OPACITY: The actor is only
  redirected through an FBO if the paint opacity is not 255. This
  value would be used if the actor wants correct opacity. It will
  avoid the overhead of using an FBO whenever the actor is fully
  opaque.

The property is implemented by installing a ClutterFlattenEffect.
ClutterFlattenEffect is a new internal class which subclasses
ClutterOffscreen to redirect the painting to an FBO. When
ClutterOffscreen paints, the effect sets an opacity override on the
actor so that the image will always contain the actor at full
opacity. The opacity is then applied to the resulting image before
painting it to the stage. This means the actor does not need to be
redrawn while the opacity is being animated.

The effect has a high internal priority so that it will always occur
before any other effects and it gets hidden from the application.

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.

af366ad750 backend: remove untested fruity backend
This backend hasn't been used for years now and so because it is

looking at moving OpenGL window system integration code down from
Clutter backends into Cogl that will be easier if we don't have to
consider this backend.

Creating a synthetic event requires direct access to the ClutterEvent
union members; this access does not map in bindings to high-level
languages, especially run-time bindings using GObject-Introspection.
It's also midly annoying from C, as it unnecessarily exposes the guts of
ClutterEvent - something we might want to fix in the future.

Add an effects chapter which gives a broad overview of
the abstract classes in the effects API, plus a short
example of how to apply one of the stock Clutter
effects (ClutterColorizeEffect).

The recipe explains how to create a custom ClutterDeformEffect
to produce a page fold (code based on ClutterPageTurnEffect).

The example code includes the effect class plus a small
application to apply it to a texture.

b3784bd2b4 event: Add a setter for the device field
When synthesizing events coming from input devices it should be
possible to just call a setter function, to avoid a huge switch
on the type of the event.

Clutter should also store the device pointer inside the private
data, for faster access of the pointer in allocated events.

Finally, the get_device_id() and get_device_type() accessors should
just be wrappers around clutter_event_get_device(), to reduce the
amount of code duplication.

2dba3e8cbf matrix: Adds experimental cogl_matrix_{transform,project}_points
This add two new function that allows us to transform or project an
array of points instead of only transforming one point at a time. Recent
benchmarking has shown cogl_matrix_transform_point to be a bottleneck
sometimes, so this should allow us to reduce the overhead when
transforming lots of vertices at the same time, and also reduce the cost
of 3 component, non-projective transforms.

For now they are marked as experimental (you have to define
COGL_ENABLE_EXPERIMENTAL_API) because there is some concern that it
introduces some inconsistent naming. cogl_matrix_transform_point would
have to be renamed cogl_matrix_project_point to be consistent, but that
would be an API break.
