ArrayBuffer <-> QByteArray

[pderocco]

I was wondering if the automatic conversion between these QML and C++ types involves copying the data, or if Copy On Write sharing is used. I found this on some other git site, and it seems to imply that the authors modified the QML code to share data, but I'm not sure if I'm reading it right, or if that's ever been incorporated back into the upstream main line code, or if it only applies to one direction. Does anyone know for sure?
