newly written code. you can effectively replace it with a simple
Clutter.Actor with a background color, or (in case you need fancier
drawing features like borders or rounded corners) with a
Clutter.Canvas content.
I would not use a deprecated class in a tutorial either.
the reason you don't see a child of a Clutter.Rectangle is that

Rectangle does not paint its children, for backward compatibility. you
can add children to it, but they will never be painted — unless you
subclass Clutter.Rectangle and override the `paint` virtual function.
again, I strongly encourage you not to use deprecated functionality,
especially when creating documentation.
I look forward to reading your tutorial!
ciao,
Emmanuele.
