Ooh, this is news to me.
I think we should document this somewhere, if it isn't already done (I
searched but couldn't find anything). I'm happy to volunteer if
necessary. Could you please provide a list of built-in properties of

Also, what do you think of some API that returns a list of available
properties? (similar to QObject::dynamicPropertyNames() )
