Firstly, this improves performance on a larger pages. But it also
prevents browser crashes a very large pages by setting a limit to how
much work is done per frame.
Also includes:
* Thread safe cell map for simultaneously reading and writing to the
buffered frame of TTY cells.
* Improved webext tests so that they programmaticlly build DOM rects
based off simple text strings.
