How about letting Pango take care of this all? Line breaking
algorithms are not really trivial to get right, so you better not
implement this yourself. The cairo text functions aren't called *toy*
text interface for nothing, once you want more advanced text handling
(e.g. line breaking, proper international text support with font
fallback), you really should use pango.
