[Interest] Qml .rcc by module?

[Jérôme Godbout]

Yeah, it would be nice, if I push the idea even further, you could have
your qml inside ressource too (.qml files inside the .rcc files), that
would also be nice. Mostly the external are not qml scripts but images,
movies and other files that the Qml will be usings.

The problems we are facing is more to load the .rcc file only when the qml
module start being used.

Wonder if there's a way to have a callback on the QQmlEngine to known when
it will load a new module (or all module for that matter could do the job
with it's path).

Anybody have information on the QQmlEngine::addNamedBundle() function doc
does not say anything? What is namedBundle exactly?

Thanks,
Jerome
