/**
* @defgroup Widget Widgets Extension Infrastructure
*
* This section is intended for people willing to create @b custom
* Elementary widgets or to contribute new (useful, unique) widgets
* upstream. If neither is your case, this text won't be of any use
* for you.
*
* Elementary widgets are built in a @b hierarchical fashion. The idea
* is to factorize as much code as possible between widgets with
* behavioral similarities, as long as to facilitate the creation of
* @b custom, new widgets, may the user need them.
*
* It all starts with a base class, which aggregates behaviour
* @b every Elementary widget is supposed to have:
* #Elm_Widget_Smart_Class. Every Elementary widget will be of that
* type, be it directly or by means of @b inheriting from it.
*
* #Elm_Widget_Smart_Class happens to be an @c Evas_Smart_Class. If
* you check out Evas' documentation on it, you'll see it's how one is
* supposed to create custom Evas objects, what Elementary widgets
* are.
*
* Once one instantiates an Elementary widget, since it inherits from
* #Elm_Widget_Smart_Class, the system will raise a class instance of
* that type for you. But that happens only @b once: the first time
* you ask for an Elementary widget (of a given type). All subsequent
* ones will only point to the very same class instance. Since it's
* the class which points to the functions implementing the behavior
* of objects of that type, all of the live instances of Elementary
* widgets (of that type) will share the same blob of code loaded in
* memory to execute their routines.
*
* Now go and take a look at #Elm_Widget_Smart_Class's fields. Because
* it inherits from Evas' base smart class, we got a field of that
* type as the first member, so that Evas can handle Elementary
* objects internally as if they were 'normal' Evas objects. Evas has
* the Evas-only behavior function pointers in there, so it's all it
* needs.
*
* Then, comes a version field, so that whenever we got to update or
* change the fields on our base smart class, there'll be a runtime
* check of the version expected by Elementary and the one provided by
* any code linking with it. A mismatch will show the developer of
* that code he/she needs to recompile and link its code to a newer
* version of Elementary.
*
* The next fields are the class functions themselves. We call them
* 'virtual' because, as in object-oriented languages, one is supposed
* here to override them on inheriting classes. On most of
* inheritances you'll probably want to call the parent's version of
* the class function too: you must analyse each case to tell.
*
* Take a look at #Elm_Widget_Smart_Data. That's private data bound to
* each Elementary object @b instance. It aggregates data needed for
* all widgets, since it's meant for the #Elm_Widget_Smart_Class-typed
* ones.
*
* When inheriting from that base type, instance data for this new
* class has to have, as the first member, a field of type
* #Elm_Widget_Smart_Data. This has to be respected recursively -- if
* a third class is to be created inheriting from the one that is a
* direct 'child' of #Elm_Widget_Smart_Class, then the private data on
* this third class has to have, as its first field, a variable of the
* type of the private data of the second class (its parent), direct
* child of #Elm_Widget_Smart_Class.
*
* It is from the base private data, #Elm_Widget_Smart_Data, that we
* reach an object's class functions, by the given object
* instance. This is the reason of the first field of that struct: a
* pointer set to point to its class when the object is instantiated.
*
* The following figure illustrates the widget inheritance schema.
