If we keep the append/prepend terminology and switch the semantics (for 
reasons explained by Jim), is that a good API? The semantic would then 
be defined as "append" means the same thing as adding the transform to 
the end of Node's transform list.

Or, Jim, do you have a better naming suggestion?
