Fix a few remaining issues and allow setting the scene as a property

I think after merging this a release is in order :)

Nice work!

As far as releasing go, are there any more formal requirements to work out? For instance, is a test suite and docs formally required? Or can docs live in the QML package so it's all in one place? We probably also ought to add a license; I would say MIT makes the most sense since the original code i ripped from your repo is MIT, and it is also my favorite license anyway.

Before releasing, it would also make sense to add you as an author in Project.toml. After all, most of the original code was written by you even though it was committed by me in this repo, and you have done all the work of updating it, so you should get credit.

Thanks for the useful suggestions, all should be OK now. I'll trigger a release, there will then be a 3 day waiting period.
