* Here, @a data is an arbitrary pointer to be used as desired. Note
* that @a emission and @a source correspond respectively to the first
* and the second parameters at the SIGNAL_EMIT action.

* in either the emission or source name, e.g.
*
* @code
* edje_object_signal_callback_add(obj, "mouse,down,*", "button.*", NULL);
* @endcode
*
* Here, any mouse down events on an edje part whose name begins with
* "button." will trigger the callback. The actual signal and source
* names will be passed in to the @a emission and @a source parameters
* of the callback function (e.g. "mouse,down,2" and "button.close").
