* @image latex img/widget/flip/preview-00.eps
*
* This widget holds 2 content objects(Evas_Object): one on the front and one
* on the back. It allows you to flip from front to back and vice-versa using
* various animations.
*
* If either the front or back contents are not set the flip will treat that
* as transparent. So if you wore to set the front content but not the back,
* and then call elm_flip_go() you would see whatever is below the flip.
*
* For a list of supported animations see elm_flip_go().
*
* Signals that you can add callbacks for are:
* "animate,begin" - when a flip animation was started
* "animate,done" - when a flip animation is finished
*
* Default content parts of the flip widget that you can use for are:
* @li "front" - A front content of the flip
* @li "back" - A back content of the flip
*
* Supported elm_object common APIs.
* @li @ref elm_object_part_content_set
* @li @ref elm_object_part_content_get
* @li @ref elm_object_part_content_unset
*
* @ref tutorial_flip show how to use most of the API.
