* #ClutterContainer : cally_actor implements some of his methods based on
* #ClutterContainer interface, although there are the posibility to not
* implement it. Could be strange to do that but:
* * Some methods (like get_n_children and ref_child) are easily implemented using
* this interface so a general implementation can be done
* * #ClutterContainer is a popular interface, so several classes will implement
* that.
* * So we can implement a a11y class similar to GailContainer for each clutter
* object implementing that, and their clutter subclasses will have a proper
* a11y class, but not if they are parallel classes (ie: #ClutterGroup,
* #TinyFrame, #TinyScrollView)
* * So, on all this objects, will be required to reimplement again some methods
* on the objects.
* * A auxiliar object (a kind of a11y specific #ClutterContainer implementation)
* could be used to implement this methods in only a place, anyway, this will
* require some code on each concrete class to manage it.
* * So this implementation is based in that is better to manage a interface
* on the top abstract object, instead that C&P some code, with the minor
* problem that we need to check if we are implementing or not the interface.
*
* This methods can be reimplemented, in concrete cases that we can get ways more
* efficient to implement that. Take a look to #CallyGroup as a example of this.
*
* Anyway, there are several examples of behaviour changes depending of the current
* type of the object you are granting access.
*
* TODO,FIXME: check if an option would be to use a dynamic type, as
* it has been done on the webkit a11y implementation:
* See: https://bugs.webkit.org/show_bug.cgi?id=21546

* #AtkAction implementation: on previous releases ClutterActor added
* the actions "press", "release" and "click", as at that time some
* general-purpose actors like textures were directly used as buttons.
