sl@0: Provides methods to map a TLanguage type to some pre-defined glyph samples.
sl@0: Samples are defined per writing script, e.g. specifying ELangFrench or
sl@0: ELangGerman will return the same set of samples.
sl@0: These samples are typically the tallest and 'deep'est characters w.r.t
sl@0: various scripts, useful for font rasterizers when calculating metrics.
