697 Word wraps a string. The wordWidth function is guaranteed to be called exactly
698 once for each word in the string, so it may be stateful, no idea what that
699 would be good for any more. At the beginning of the string, it will be called
700 for the char 0 to initialize a clean state, and then once with the string " "
701 (a space) so the routine knows how long a space is.
703 In case no single character fits into the given width, the wordWidth function
704 must return the width of exactly one character.
706 Wrapped lines get the isContinuation flag set and are continuationWidth less wide.
