/**
 * Add (register) a callback function to a given canvas event.
 *
 * @param e Canvas to attach a callback to
 * @param type The type of event that will trigger the callback
 * @param func The (callback) function to be called when the event is
 *        triggered
 * @param data The data pointer to be passed to @p func
 *
 * This function adds a function callback to the canvas @p e when the
 * event of type @p type occurs on it. The function pointer is @p
 * func.
 *
 * In the event of a memory allocation error during the addition of
 * the callback to the canvas, evas_alloc_error() should be used to
 * determine the nature of the error, if any, and the program should
 * sensibly try and recover.
 *
 * A callback function must have the ::Evas_Event_Cb prototype
 * definition. The first parameter (@p data) in this definition will
 * have the same value passed to evas_event_callback_add() as the @p
 * data parameter, at runtime. The second parameter @p e is the canvas
 * pointer on which the event occurred. The third parameter @p
 * event_info is a pointer to a data structure that may or may not be
 * passed to the callback, depending on the event type that triggered
 * the callback. This is so because some events don't carry extra
 * context with them, but others do.
 *
 * The event type @p type to trigger the function may be one of
 * #EVAS_CALLBACK_RENDER_FLUSH_PRE, #EVAS_CALLBACK_RENDER_FLUSH_POST,
 * #EVAS_CALLBACK_CANVAS_FOCUS_IN, #EVAS_CALLBACK_CANVAS_FOCUS_OUT,
 * #EVAS_CALLBACK_CANVAS_OBJECT_FOCUS_IN and
 * #EVAS_CALLBACK_CANVAS_OBJECT_FOCUS_OUT. This determines the kind of
 * event that will trigger the callback to be called. Only the last
 * two of the event types listed here provide useful event information
 * data -- a pointer to the recently focused Evas object. For the
 * others the @p event_info pointer is going to be @c NULL.
 *
 * Example:
 * @dontinclude evas-events.c
 * @skip evas_event_callback_add(d.canvas, EVAS_CALLBACK_RENDER_FLUSH_PRE
 * @until two canvas event callbacks
 *
 * Looking to the callbacks registered above,
 * @dontinclude evas-events.c
 * @skip called when our rectangle gets focus
 * @until let's have our events back
 *
 * we see that the canvas flushes its rendering pipeline
 * (#EVAS_CALLBACK_RENDER_FLUSH_PRE) whenever the @c _resize_cb
 * routine takes place: it has to redraw that image at a different
 * size. Also, the callback on an object being focused comes just
 * after we focus it explicitly, on code.
 *
 * See the full @ref Example_Evas_Events "example".
 *
 * @note Be careful not to add the same callback multiple times, if
 * that's not what you want, because Evas won't check if a callback
 * existed before exactly as the one being registered (and thus, call
 * it more than once on the event, in this case). This would make
 * sense if you passed different functions and/or callback data, only.

 *
 * - #EVAS_CALLBACK_MOUSE_OUT: @p event_info is a pointer to an
 *   #Evas_Event_Mouse_Out struct\n\n
 *   This event is triggered exactly like #EVAS_CALLBACK_MOUSE_IN is,
 *   but it occurs when the mouse pointer exits an object's area. Note
 *   that no mouse out events will be reported if the mouse pointer is
 *   implicitly grabbed to an object (mouse buttons are down, having
 *   been pressed while the pointer was over that object). In these
 *   cases, mouse out events will be reported once all buttons are
 *   released, if the mouse pointer has left the object's area. The
 *   indirect ways of taking off the mouse pointer from an object,
 *   like cited above, for #EVAS_CALLBACK_MOUSE_IN, also apply here,
 *   naturally.
 *
 * - #EVAS_CALLBACK_MOUSE_DOWN: @p event_info is a pointer to an
 *   #Evas_Event_Mouse_Down struct\n\n
 *   This event is triggered by a mouse button being pressed while the
 *   mouse pointer is over an object. If the pointer mode for Evas is
 *   #EVAS_OBJECT_POINTER_MODE_AUTOGRAB (default), this causes this
 *   object to <b>passively grab the mouse</b> until all mouse buttons
 *   have been released: all future mouse events will be reported to
 *   only this object until no buttons are down. That includes mouse
 *   move events, mouse in and mouse out events, and further button
 *   presses. When all buttons are released, event propagation will
 *   occur as normal (see #Evas_Object_Pointer_Mode).
 *
 * - #EVAS_CALLBACK_MOUSE_UP: @p event_info is a pointer to an
 *   #Evas_Event_Mouse_Up struct\n\n
 *   This event is triggered by a mouse button being released while
 *   the mouse pointer is over an object's area (or when passively
 *   grabbed to an object).
 *
 * - #EVAS_CALLBACK_MOUSE_MOVE: @p event_info is a pointer to an
 *   #Evas_Event_Mouse_Move struct\n\n
 *   This event is triggered by the mouse pointer being moved while
 *   over an object's area (or while passively grabbed to an object).
 *
 * - #EVAS_CALLBACK_MOUSE_WHEEL: @p event_info is a pointer to an
 *   #Evas_Event_Mouse_Wheel struct\n\n
 *   This event is triggered by the mouse wheel being rolled while the
 *   mouse pointer is over an object (or passively grabbed to an
 *   object).
 *
 * - #EVAS_CALLBACK_MULTI_DOWN: @p event_info is a pointer to an
 *   #Evas_Event_Multi_Down struct
 *
 * - #EVAS_CALLBACK_MULTI_UP: @p event_info is a pointer to an
 *   #Evas_Event_Multi_Up struct
 *
 * - #EVAS_CALLBACK_MULTI_MOVE: @p event_info is a pointer to an
 *   #Evas_Event_Multi_Move struct
 *
 * - #EVAS_CALLBACK_AXIS_UPDATE: @p event_info is a pointer to an
 *   #Evas_Event_Axis_Update struct
 *
 * - #EVAS_CALLBACK_FREE: @p event_info is @c NULL \n\n
 *   This event is triggered just before Evas is about to free all
 *   memory used by an object and remove all references to it. This is
 *   useful for programs to use if they attached data to an object and
 *   want to free it when the object is deleted. The object is still
 *   valid when this callback is called, but after it returns, there
 *   is no guarantee on the object's validity.
 *
 * - #EVAS_CALLBACK_KEY_DOWN: @p event_info is a pointer to an
 *   #Evas_Event_Key_Down struct\n\n
 *   This callback is called when a key is pressed and the focus is on
 *   the object, or a key has been grabbed to a particular object
 *   which wants to intercept the key press regardless of what object
 *   has the focus.
 *
 * - #EVAS_CALLBACK_KEY_UP: @p event_info is a pointer to an
 *   #Evas_Event_Key_Up struct \n\n
 *   This callback is called when a key is released and the focus is
 *   on the object, or a key has been grabbed to a particular object
 *   which wants to intercept the key release regardless of what
 *   object has the focus.
 *
 * - #EVAS_CALLBACK_FOCUS_IN: @p event_info is @c NULL \n\n
 *   This event is called when an object gains the focus. When it is
 *   called the object has already gained the focus.
 *
 * - #EVAS_CALLBACK_FOCUS_OUT: @p event_info is @c NULL \n\n
 *   This event is triggered when an object loses the focus. When it
 *   is called the object has already lost the focus.
 *
 * - #EVAS_CALLBACK_SHOW: @p event_info is @c NULL \n\n
 *   This event is triggered by the object being shown by
 *   evas_object_show().
 *
 * - #EVAS_CALLBACK_HIDE: @p event_info is @c NULL \n\n
 *   This event is triggered by an object being hidden by
 *   evas_object_hide().
 *
 * - #EVAS_CALLBACK_MOVE: @p event_info is @c NULL \n\n
 *   This event is triggered by an object being
 *   moved. evas_object_move() can trigger this, as can any
 *   object-specific manipulations that would mean the object's origin
 *   could move.
 *
 * - #EVAS_CALLBACK_RESIZE: @p event_info is @c NULL \n\n
 *   This event is triggered by an object being resized. Resizes can
 *   be triggered by evas_object_resize() or by any object-specific
 *   calls that may cause the object to resize.
 *
 * - #EVAS_CALLBACK_RESTACK: @p event_info is @c NULL \n\n
 *   This event is triggered by an object being re-stacked. Stacking
 *   changes can be triggered by
 *   evas_object_stack_below()/evas_object_stack_above() and others.
 *
 * - #EVAS_CALLBACK_DEL: @p event_info is @c NULL.
 *
 * - #EVAS_CALLBACK_HOLD: @p event_info is a pointer to an
 *   #Evas_Event_Hold struct
 *
 * - #EVAS_CALLBACK_CHANGED_SIZE_HINTS: @p event_info is @c NULL.
 *
 * - #EVAS_CALLBACK_IMAGE_PRELOADED: @p event_info is @c NULL.
 *
 * - #EVAS_CALLBACK_IMAGE_UNLOADED: @p event_info is @c NULL.
 *
 * @note Be careful not to add the same callback multiple times, if
 * that's not what you want, because Evas won't check if a callback
 * existed before exactly as the one being registered (and thus, call
 * it more than once on the event, in this case). This would make
 * sense if you passed different functions and/or callback data, only.
 *
 * Example:
 * @dontinclude evas-events.c
 * @skip evas_object_event_callback_add(
 * @until }
 *
 * See the full example @ref Example_Evas_Events "here".
