  25  * Transit (see Warning below) is designed to set the various effects for the
  26  * Evas_Object such like translation, rotation, etc. For using Effects, Create
  27  * transit and insert effects which are interesting.
  28  * Once effects are inserted into transit, transit will manage those effects.
  29  * (ex deleting).
  30  *
  31  * Example:
  32  * @code
  33  * Elm_Transit *trans = elm_transit_add();
  34  * elm_transit_object_add(trans, obj);
  35  * void *effect_context = elm_transit_effect_translation_context_new(0.0, 0.0,
  36  *                                                               280.0, 280.0);
  37  * elm_transit_effect_add(transit,
  38  *                        elm_transit_effect_translation_op, effect_context,
  39  *                        elm_transit_effect_translation_context_free);
  40  * elm_transit_duration_set(transit, 1);
  41  * elm_transit_auto_reverse_set(transit, EINA_TRUE);
  42  * elm_transit_tween_mode_set(transit, ELM_TRANSIT_TWEEN_MODE_DECELERATE);
  43  * elm_transit_repeat_times_set(transit, 3);
  44  * @endcode
  45  *
  46  * @warning We strongly recomend to use elm_transit just when edje can not do
  47  * the trick. Edje has more advantage than Elm_Transit, it has more flexibility and
  48  * animations can be manipulated inside the theme.
