Title: Backport poly

There are a few bug fixes here, but mostly this updates the documentation and improves the numerics of fromroots and roots, which are now good to about degree 50 for equally spaced roots from -1 to 1.

It was tempting to just pull the whole thing back for the improved testing, but I resisted.
