I have an answer that I've been working away at and updating as I found out more and more information (or fixed typos). There was a fair bit of effort involved experimenting with different values and finding links etc...
Now I see that it has automatically changed into a community wiki answer. This is a bit gutting, as I think I was the only person contributing to it. I'm all for contributing to the community and sharing answers, but it doesn't really make sense in this case.
Can this be reverted?
