for the char 0 to initialize a clean state, and then once with the string " "
(a space) so the routine knows how long a space is.
+In case no single character fits into the given width, the wordWidth function
+must return the width of exactly one character.
+
Wrapped lines get the isContinuation flag set and are continuationWidth less wide.
The sum of the return values of the processLine function will be returned.
