> +        This improves this rendering path by a factor of ~4. The rest of FormatConverter may require similar improvements.

The best thing to do here would be to file a bugzilla bug for the rest of the improvements, and reference it. Like "Filed webkit.org/b/9999 for further improvements".

Remove the comment. It only means something to you.
