[noise] Pattern transformations

[Alex]

I'm a little unclear on the idea of pattern transformations. Up until
this point the transformations I've seen have only been applied to one
or two patterns in an ad-hoc manner (e.g. fallback). It's not clear that
any single formal algorithmic transformation can be applied universally
to all patterns.

In theory, could such a transformation exist? If it can, that would be
incredibly beautiful and elegant, because it would allow us to have a
notion of composition (among other things).
