Currently the way we render tokens in the render queue is that we take the final tokens, convert each token into a
Vecof concrete token types, and thenflat_mapthem all together. This allocates a whole lot of intermediary Vecs for no real benefit.This PR passes the single output Vec to each of these conversion methods and has each one just append to it directly.
