Widget description
------------------
An Elementary photo widget is intended for displaying a photo, for
ex., 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.
This widget relies on an internal :py:class:`~efl.elementary.icon.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:
- ``clicked`` - This is called when a user has clicked the photo
- ``drag,start`` - One has started dragging the inner image out of the photo's
frame
- ``drag,end`` - One has dropped the dragged image somewhere
