+ * Associate the given object to this ecore evas.
+ *
+ * Association means that operations on one will affect the other, for
+ * example moving the object will move the window, resize the object will
+ * also affect the ecore evas window, hide and show applies as well.
+ *
+ * This is meant to simplify development, since you often need to associate
+ * these events with your "base" objects, background or bottom-most object.
+ *
+ * Be aware that some methods might not be what you would like, deleting
+ * 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,
+ * like ecore_evas_hide(). Just remember that if you override delete_request
+ * and still want to delete the window/object, you must do that yourself.
+ *
+ * Since we now define delete_request, deleting windows will not quit
+ * main loop, if you wish to do so, you should listen for EVAS_CALLBACK_FREE
+ * on the object, that way you get notified and you can call
+ * ecore_main_loop_quit().
+ *
+ * Flags can be OR'ed of:
+ * - ECORE_EVAS_OBJECT_ASSOCIATE_BASE (or 0): to listen to basic events
+ * like delete, resize and move, but no stacking or layer are used.
+ * - 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.
+ * - 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().
+ *
+ * @param ee The Ecore_Evas to associate to @a obj
+ * @param obj The object to associate to @a ee
