*
* @brief The Elementary photo widget is intended for displaying a photo,
* for eg., a person's image (contact).
*
* Simple, yet with a very specific purpose. It has a decorative frame around
* the inner image itself, on the default theme. If and while no photo is set
* on it, it displays a person icon, indicating it's a photo placeholder.
*
* This widget relies on an internal @ref Icon, so that the APIs of
* these two widgets are similar (drag and drop is also possible here,
* for example).
*
* Signals that you can add callbacks for are:
* - @c "clicked" - This is called when a user has clicked the photo.
* - @c "drag,start" - One has started dragging the inner image out of the
* photo's frame.
* - @c "drag,end" - One has dropped the dragged image somewhere.
*
