Optimization opportunity - priori_cast

[ColinGilbert]

There is an interesting writeup on a so-called priori cast, a dynamic cast replacement that works very quickly at casting from a base type to a derived typed for when the info is known at compile-time. It seems ideal for creating joints. Drawback is the upcasting is slower, but that isn't a usecase I saw in the examples.
