This solves a crash on GNOME Shell, as compute the extents
for some StWidgets could lead to call st_widget_get_theme_node,
and it is a fatal error to call this on a widget that it not
beed added to a stage.
ATK_ROLE_CANVAS is not a suitable role, as the user (in general) can't
draw on the Stage. CallyStage implements AtkWindow, so the proper role
is ATK_ROLE_WINDOW
Removing atkcomponent, focus_tracker, etc. Emitting focus state change
from the stage. Now things are more simple, and stop to use some
of the soon-to-be-deprecated signals on ATK.
Cally is doing a bunch of list traversals through the list returned by
ClutterContainer.get_children(); this means a traversal already, plus
a bunch of allocations. We can do better than that, now that we have
a proper graph iteration API inside ClutterActor.
Using the default stage as a fallback is wrong in all circumstances.
In this specific case, if an actor is not associated to a stage then it
cannot possibly be the key focus.
For god-knows-what reason, at-spi is trying various formats
of strings when registering listeners, triggering an ugly
(gnome-shell:4411): Clutter-WARNING **: invalid object type create
warning in .xsession-errors. Stop doing that.
Also don't leak temporary string arrays that are a side-effect
of passing parameters around as formatted strings.

Cally was initially created with Clutter 0.6 in mind. To check
recursively the visibility of a actor a custom method was added.
Since 0.8.4 clutter_actor_get_pain_visibility provides
the same functionality.
Also removed a dummy method. Lets add methods that provide a real
functionality.
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.
Those were added on the old "just for automatic testing" times. That was
somewhat silly on that moment. Now is just silly (ie: having the stage
returning as default name "Stage").
The real description should be set by the app, or provided by the
context of a specific actor feature (like the tooltip on StWidget).
The current information provided by the default description can be
mostly obtained from the ATK_ROLE, and the indirect debugging
advantage of having always a meaningful description is just not enough
to justify them, and you can solve that by proper debug logging.

Adding an action should allow passing a user data pointer, and have a
notification action that gets called when removing the action. This
allows introspection and language bindings to attach custom data to the
action - for instance, the real callable object that should be invoked.

After commit 8dd8fbdb some errors appear if you try work directly
against cally:
* cally.pc.in removed some elements. After install clutter, doing
pkg-config --cflags cally-1.0
fails due missing winsys
* cally headers were moved from clutter-1.0/cally to
clutter-1.0/clutter/cally. Applications using it (yes I know,
nobody is officially using it) would require to:
* Change their include.
* Add directly a dependency to cally, in order to use the cally.pc
file with the correct directory include.
Note: Take into account that accessibility support still works (ie:
clutter_get_accessibility_enabled). This bug only prevents
applications to work directly against cally (ie: create a CallyActor
subclass)

*** WARNING: THIS COMMIT CHANGES THE BUILD ***
Do not recurse into the backend directories to build private, internal
libraries.
We only recurse from clutter/ into the cogl sub-directory; from there,
we don't recurse any further. All the backend-specific code in Cogl and
Clutter is compiled conditionally depending on the macros defined by the
configure script.
We still recurse from the top-level directory into doc, clutter and
tests, because gtk-doc and tests do not deal nicely with non-recursive
layouts.
This change makes Clutter compile slightly faster, and cleans up the
build system, especially when dealing with introspection data.
Ideally, we also want to make Cogl part of the top-level build, so that
we can finally drop the sed trick to change the shared library from the
GIR before compiling it.
Currently disabled:
‣ OSX backend
‣ Fruity backend
Currently enabled but untested:
‣ EGL backend
‣ Windows backend
Toolkits and applications not written in C might still need access to
the Cally API to write accessibility extensions based on it for their
own native elements.
Previously "window:create" and "window:destroy" were emitted on
CallyUtil. Although it works, and CallyUtil already have callbacks to
stage_added/removed signals, I think that it is more tidy/clear to do
that on CallyRoot:
* CallyRoot already has code to manage ClutterStage addition/removal
* In fact, we can see CallyRoot as the object exposing the a11y
information from ClutterStageManager, so it fits better here.
* CallyUtil callbacks these signals are related to key event
listeners (key snooper simulation). One of the main CallyUtil
responsabilities is managing event (connecting, emitting), so I
would prefer to not start to add/mix more functionalities here.
Ideally it would be better to emit all CallyStage methods from
CallyStage, but it is clear that "create" and "destroy" are more easy
to emit from a external object
Make Cally follow the single-include header file policy of Clutter and
Cogl; this means making cally.h the single include header, and requires
a new cally-main.h file for the functions defined by cally.h.
Also:
• clean up the licensing notice and remove the FSF address;
• document the object structures (instance and class);
• G_GNUC_CONST-ify the get_type() functions;
• reduce the padding for CallyActor sub-classes;
• reduce the amount of headers included.
Initialize the accessibility support calling cally_accessibility_init
Take into account that this is required to at least be sure that
CallyUtil class is available.
It also modifies cally_accessibility_module_init in order to return
if the initialization was fine (and the name, removing the module word).
It also removes the gnome accessibility hooks, as it is not anymore
module code.
Solves CB#2098
This commit includes a method to init the a11y support. Two main purposes:
* Register the different Atk factories.
* Ensure that there are a AtkUtil implementation class available.
Part of CB#2097
The Clutter Accessibility Library is an implementation of the ATK,
the Accessibility Toolkit, which exposes Clutter actors to accessibility
tools. This allows not only writing accessible user interfaces, but also
allows testing and verification frameworks based on A11Y technologies to
inspect and test a Clutter scene graph.
