/**
 * @defgroup Slideshow Slideshow
 *
 * This object display a list of object (generally a list of images) and some actions like
 * next/previous are used to navigate. The animations are defined in the theme,
 * consequently new animations can be added without having to update the
 * applications.
 *
 * The slideshow use 2 callbacks to create and delete the objects displayed. When an item
 * is displayed the function itc->func.get() is called. This function should create the object,
 * for example the object can be an evas_object_image or a photocam. When a object is no more
 * displayed the function itc->func.del() is called, the user can delete the dana associated to the item.
 *
 * Signals that you can add callbacks for are:
 *
 * "changed" - when the slideshow switch to another item
