ClutterContent is an interface for creating delegate objects that handle
what an actor is going to paint.
Since they are a newly added type, they only hook into the new PaintNode
based API.
The position and size of the content is controlled in part by the
content's own preferred size, and by the ClutterContentGravity
enumeration.
ClutterScript should be able to automatically call gettext() and friends
on strings loaded from a UI definition, prior to passing the string to
the object it is constructing.
The basic implementation is trivial:
- set a translation domain on the ClutterScript instance
- mark the translatable strings inside the JSON data, like:
"property" : {
"translatable" : true,
"string" : "a translatable string"
}
The hard part is now getting the tools we use to extract the
translatable strings to understand the JSON format we use inside
ClutterScript.
This has been converted to a Cogl-based test in the cogl source tree
so there is no need to maintain it here anymore.

In a separate branch, this test has become quite complicated and
involves multiple files and its own configure options. Instead of
cluttering up the clutter source tree it has now been moved to its own
repo at:

It's the conformance test suite: there's no need to namespace the files,
just like there's no need to namespace the units.
This commit does not change the Cogl tests: they will be moved to Cogl
over time, and it's easier to do if we leave them as they are.
Since Cogl has started restricting what cogl 1.x api is exposed when
COGL_ENABLE_EXPERIMENTAL_2_0_API is defined and since we build all
Clutter internals with COGL_ENABLE_EXPERIMENTAL_2_0_API defined this
patch makes a first pass at reducing our internal use of the Cogl 1.x
api.
The most notable api that's no longer exposed to us internally is
the cogl_material_ api so this switches all Clutter internals to use the
cogl_pipeline_ api instead. This patch also makes quite a bit of
progress removing internal uses of CoglHandle although there is still
more to go.
The experimental cogl_texture_pixmap_x11_new() api was recently changed
to take an explicit context argument and return a GError on failures.
This updates Clutter's use of the api accordingly.
A lot of the conformance tests that were just testing Cogl
functionality have been ported to be standalone Cogl tests in the Cogl
source tree. This patch removes those from Clutter so we don't have to
maintain them in two places.

ClutterActor should be emitting signals defined on the ClutterContainer
interface, as well as ensuring that manipulating the scene graph is
still possible from within them.
The new unit checks that we're emitting signals, by implementing
something similar to the Bin class available in toolkits like gtk, st,
and mx — i.e. a container that can only hold one child at any given
point.
Some of Cogl's experimental apis have changed so that the buffer apis
now need to be passed a context argument and some drawing apis have been
replaced with cogl_framebuffer_ drawing apis that take explicit
framebuffer and pipeline arguments.
These changes were made as part of Cogl moving towards a more stateless
api that doesn't rely on a global context.
This patch updates Clutter to work with the latest Cogl api and bumps
the required Cogl version to 1.9.5.

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.

Something is causing a deadlock when using clutter_threads_* API inside
the offscreen redirect conformance test. The conformance tests are
pretty insane anyway, so for the time being, let's put g_timeout_add()
back in while we figure out the issue.
* Abstracts the buffer for text in ClutterText
* Allows implementation of undo/redo.
* Allows use of non-pageable memory for text
in the case of sensitive passwords.
* Implement a test with two ClutterText using the same
buffer.

ClutterActor provides four methods for changing the paint sequence order
of its children:
raise_top()
raise()
lower()
lower_bottom()
The first and last one being just wrappers around raise() and lower(),
respectively. These methods have various issues: they omit the parent,
preferring to retrieve it from the actor passed as the first argument;
this does not match the new style of API introduced to operate on the
list of children of an actor.
Additionally, the raise() and lower() methods of ClutterActor call into
the Container interface, and are not really aptly named (raise() in
particular collides with the completely unrelated 'raise' keyword in
Python, and usually needs to be wrapped in order to be used at all).
Furthermore, we need public methods that Container can call from its
default implementation, as well as methods to port current Container
implementations.
Finally, since we have insert_child_at_index(), we should also have an
equivalent set_child_at_index() as well.
The correct sequence of actions should be remove(old) → insert(new), not
insert(new) → remove(old). We can implement a simple delegate insertion
functions to insert the new child between the previous and next siblings
of the old child.
While we're at it, let's also add a unit test for replace_child().
