This is not directly related to your CL, but it'd be nice to start adding a bit
of comments as the method name becomes less descriptive about when and how this
one's called

Since this is called from only single place, I renamed it to more descriptive
name. Also added some comment on CSSSegmentedFontFace::fontFaceInvalidated().

 
     PassRefPtr<SimpleFontData> getFontData(const FontDescription&);
 
     struct UnicodeRange {
         ALLOW_ONLY_INLINE_ALLOCATION();
         UnicodeRange(UChar32 from, UChar32 to)
             : m_from(from)
             , m_to(to)
         {
         }
