 * to go and delete or alter the object inside this callbacks, simply make
 * a note that the recalculation has taken place and then do something about
 * it outside the callback. To register a callback use code like:
 *
 * @code
 *    evas_object_smart_callback_add(edje_obj, "recalc", my_cb, my_cb_data);
 * @endcode
 *
 * @see evas_object_smart_callback_add()

 * to initialize the library, with edje_init(), or unexpected behavior

/**
 * @brief Adds a callback for an arriving Edje signal, emitted by a given Edje
 * object.
 *
 * Edje signals are one of the communication interfaces between code and a
 * given Edje object's theme. With signals, one can communicate two string
 * values at a time, which are: - "emission" value: the name of the signal, in
 * general - "source" value: a name for the signal's context, in general
 *
 * Though there are those common uses for the two strings, one is free to use
 * them however they like.
 *
 * Signal callback registration is powerful, in the way that  blobs may be used
 * to match multiple signals at once. All the "*?[\" set of @c fnmatch()
 * operators can be used, both for emission and source.
 *
 * Edje has  internal signals it will emit, automatically, on various actions
 * taking place on group parts. For example, the mouse cursor being moved,
 * pressed, released, etc., over a given part's area, all generate individual
 * signals.
 *
 * By using something like edje_object_signal_callback_add(obj, "mouse,down,*",
 * "button.*", signal_cb, NULL); being @ref "button.*" the pattern for the
 * names of parts implementing buttons on an interface, you'd be registering
 * for notifications on events of mouse buttons being pressed down on either of
 * those parts (those events all have the @"mouse,down," common prefix on their
 * names, with a suffix giving the button number). The actual emission and
 * source strings of an event will be passed in as the  emission and  source
 * parameters of the callback function (e.g. "mouse,down,2" and
 * @"button.close"), for each of those events.
 *
 * @note See @ref edcref "the syntax" for EDC files See also
 * @ref edje_object_signal_emit() on how to emits Edje signals from code to a
 * an object @ref edje_object_signal_callback_del_full()
 *
 * @param[in] emission The signal's "emission" string
 * @param[in] source The signal's "source" string
 * @param[in] func The callback function to be executed when the signal is
 * emitted.
 * @param[in] data A pointer to data to pass in to func.
