This makes the rendering objects with position ( 0 ; 0 ) appear in the top-left corner. This is
the same behavior we get when using the default View of a SFML window. To change the
center of the view we can call View::setCenter() or View::move() ; here is an
example:

the center of the screen; here is the result:
