[Interest] How to avoid qml engine repeatedly copying and garbage collecting qstringlists?

[NIkolai Marchenko]

Oh, I see, yeah, that makes sense. Just singleton a wrapper,

The question though is whether this would be a singleton per qmlengine. If
it will, then that's a nogo as the list of loaded fonts needs to exist once
regardless of how much engines are running
