    fully dynamic layout engine in the future. Other improvements in NetSurf
    3.0 include completely new textarea support, ability to fetch and parse CSS
    in parallel with HTML documents, extensive behind-the-scenes refactoring,
    and a host of smaller changes and fixes. A more complete listing is
