Incorporated most of Emilo's changes. His VG changes lead to a panic from window server. It may be a circular deadlockproblem where Wserv is a client of EGL which is a client of Wserv, thus circular. Need to look at it further. I also fixed the arrangement of def files, and didn't take the VG mmp file changes, as I don't think they are appropriate to a stand alone real EGL implmentation. Still need to pull in Emilo's graphicscomposition changes.

/**
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.
