[Interest] Replacing QScript with QML

[Jason H]

Oh, and I just realized that QtQuick 2  in 5.8 now depends on a GUI, so your Qt Script will try to make some kind of UI call.

The good thing there is a raster backend now available.  But I don't know about a dummy backend.

Just make sure you give the object the proper parenting and ownership and delete them properly.
