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