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.

72caef0de0 cookbooks/examples: Use g_signal_handlers_disconnect_by_func()
The disconnect_matched() function is a bit too complicated, and its
simpler wrapper disconnect_by_func() is functionally equivalent in the
cases used by the cookbook examples.

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.

7d233241f1 Fix include location for cogl-pango.h
In Cogl, cogl-pango.h has moved to <cogl-pango/cogl-pango.h>. When
using the experimental 2.0 API (which Clutter does) it is no longer
possible to include it under the old name of <cogl/cogl-pango.h> so we
need to update the include location.

57a5f2296a docs: Remove checks for whether an effect is disabled
pre_paint() and post_paint() implementations don't need
to check whether an effect is disabled: Clutter will
not apply an effect unless it is enabled.

So remove code which checks whether the effect is
enabled or disabled from the example applications and the
documentation.

b5af8fbfac docs: Add recipe about implementing a ClutterEffect
Add a recipe showing how to implement two simple
effects, based on ClutterEffect: an always gray background,
and a border with configurable width and color.

Also explains the necessity to queue a redraw on
the associated actor if the effect's properties change,
and shows how to implement that.

The example gives the GObject code for both effects,
as well as an example application showing how to use them.
The example also demonstrates how to disable/enable an effect,
making the border round an actor togglable.

74de3cfdf3 docs: Add effects chapter, with introduction and first recipe
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.

cf18836ca0 docs: Add recipe for animating an actor on a curved path
Show how to animate an actor using a ClutterPathConstraint.

This demonstrates how to get effects similar to
ClutterPathBehaviour with the modern animation APIs.

Includes 3 examples:

1) Simple ClutterPathConstraint used with implicit animations
2) ClutterPathConstraint used to simulate circular animation,
using ClutterAnimator
3) Creating simple curved path animations with non-linear
easing

c9d0f8b26e cookbook: Add recipe for animated scaling of an actor
Recipe explains how to animate scaling a single actor.

Also covers scaling vs. resizing, scale center, and
scaling within layouts and containers.

The first example shows how animations around each scale
gravity look, as well as tracking the transformed position
and size of the actor and displaying those.

The second example is a simple image viewer with zoom in/out
using scaling.
