This method's eventually going to need to be extended to support suggestion
markers too, at which point it clearly doesn't make sense to have this in
SpellChecker...yosin@, should I add this as a method on
DocumentMarkerController? Something like GetMarkersTouchingRange(const
EphemeralRange&, MarkerTypes)?

   void ReplaceMisspelledRange(const String&);
   void RemoveSpellingMarkers();
   void RemoveSpellingMarkersUnderWords(const Vector<String>& words);
