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