1. Use FastTransform almost everywhere …

   FastTransform used to be called TransformOrOffset and this change uses it
   in a lot of places that we used to use TypedTransform3D directly. This
   helps to avoid the cost of expensive matrix math and allows us to more
   liberally call things like `inverse()` on our transformations, since the
   worst case is that we will be retrieving the already-cached inverted
   matrix. This decreases the amount of time that FrameBuilder::build takes
   in my local CPU profiles.
