<p>The ::first-frame signal will be emitted the first time a frame
of window contents has been drawn by the application and Mutter
has had the chance to drawn that frame to the screen. If the
window starts off initially hidden, obscured, or on on a
different workspace, the ::first-frame signal will be emitted
even though the user doesn't see the contents.</p>
<p>MetaDisplay::window-created is a good place to connect to this
signal - at that point, the MetaWindowActor for the window
exists, but the window has reliably not yet been drawn.
Connecting to an existing window that has already been drawn to
the screen is not useful.</p>
