I don't think we want this.  It means creating a WebString in the browser
process.

Some suggestions:
1- Break replacement out of WebTextCheckingResult.  (This sounds bad since you
want arrays of WebTextCheckingResult objects.)
2- Define a similar struct for use in Chromium.  Copy WebTextCheckingResult to
that struct.

I'd probably go with #2.
