    21 Samples are defined per writing script, e.g. specifying ELangFrench or
       
    22 ELangGerman will return the same set of samples.
       
    23 These samples are typically the tallest and 'deep'est characters w.r.t
       
    24 various scripts, useful for font rasterizers when calculating metrics.
