 * Ecore evas is a set of functions that makes it easy to tie together ecore's
 * main loop and input handling to evas. As such it's a natural base for EFL
 * applications. While this combination makes it easy to create the basic
 * aspects all applications need, for normal applications(ones with buttons,
 * checkboxes and layouts) one should consider using Elementary.
 *
 * Ecore evas is extremely well suited for applications that are not based on
 * widgets. It has a main loop that delivers events, does basic window handling
 * and leaves all of the drawing up to the user. This works very well if used
 * in conjunction with Edje or if doing custom drawing as, for example, is done
 * in games.
 *
 * This is a list of examples of these functions:
 * @li @ref ecore_evas_basics_example_c
 * @li @ref ecore_evas_object_example_c
 * @li @ref ecore_evas_callbacks_example_c

 * either the window or the object will delete the other. If you want to
 * change that behavior, let's say to hide window when it's closed, you
 * must use ecore_evas_callback_delete_request_set() and set your own code,

 * and still want to delete the window/object, you must do that yourself.
 *
 * Since we now define delete_request, deleting windows will not quit

 *     like delete, resize and move, but no stacking or layer are used.
 * @li ECORE_EVAS_OBJECT_ASSOCIATE_STACK: stacking operations will act
 *     on the Ecore_Evas, not the object. So evas_object_raise() will
 *     call ecore_evas_raise(). Relative operations (stack_above, stack_below)
 *     are still not implemented.
 * @li ECORE_EVAS_OBJECT_ASSOCIATE_LAYER: stacking operations will act
 *     on the Ecore_Evas, not the object. So evas_object_layer_set() will
 *     call ecore_evas_layer_set().

 *
 * When a client(plug) connects, you will get the ECORE_EVAS_EXTN_CLIENT_ADD event
 * in the ecore event queue, with event_info being the image object pointer
 * passed as a void pointer. When a client disconnects you will get the
 * ECORE_EVAS_EXTN_CLIENT_DEL event.
 *
 * You can set up event handles for these events as follows:
 *
 * @code
 * static void client_add_cb(void *data, int event, void *event_info)
 * {
 *   Evas_Object *obj = event_info;
 *   printf("client added to image object %p\n", obj);
 *   evas_object_show(obj);
 * }
 *
 * static void client_del_cb(void *data, int event, void *event_info)
 * {
 *   Evas_Object *obj = event_info;
 *   printf("client deleted from image object %p\n", obj);
 *   evas_object_hide(obj);
 * }
 *
 * void setup(void)
 * {
 *   ecore_event_handler_add(ECORE_EVAS_EXTN_CLIENT_ADD,
 *                           client_add_cb, NULL);
 *   ecore_event_handler_add(ECORE_EVAS_EXTN_CLIENT_DEL,
 *                           client_del_cb, NULL);
 * }
 * @endcode
 *
 * Note that events come in later after the event happened. You may want to be
 * careful as data structures you had associated with the image object
 * may have been freed after deleting, but the object may still be around
 * awating cleanup and thus still be valid.You can change the size with something like:
 *
 * @see ecore_evas_extn_socket_listen()
 * @see ecore_evas_extn_plug_new()
 * @see ecore_evas_extn_plug_object_data_lock()
