Where are the old pango modules?

[John Emmas <johne53 tiscali co uk>]

I've built pango several times but up to now, it's always been from 
tarballs.  Recently however, I decided to switch to git sources for 
future work.  I'm building with MSVC and everything's going fine, except 
for building the various pango modules, which is puzzling me a bit.

Forgetting about 'basic-coretext' (which I assume is only relevant for 
the Apple platform) we now seem to build 4 x pango modules, namely:-

        arabic-lang
        indic-lang
        basic-win32
        basic-fc

I'm puzzled because in earlier version of pango there were many more 
modules, including  khmer, hangul, thai, hebrew and a few others. What 
happened to them?  Are they no longer needed or have they been moved 
into some other library?
