Re: how update the website for the complex layout

Oh, sorry for my poor wording.

If my memory is correct, HarfBuzz was started as the one of the infrastructure 
for the Pango.
When it was started, there were other non-HarfBuzz OpenType drivers, like Qt, 
like ICU, etc. Maybe there were more.
But now, the major players like Qt and ICU had changed to HarfBuzz. So I feel 
HarfBuzz had grown as more general framework, in comparison with its beginning.

But anyway, your pointing out "HarfBuzz is a text shaping library, not a text layout 
library" is important for the people looking for "text layout framework showing vertical 
glyphs in vertical writing mode". Maybe a simple mention on HarfBuzz is a misleading info, 
like, giving a flour to a person looking for a bread. I withdraw my proposal to replace the mention 
on Pango by the mention on HarfBuzz. More elaboration is needed.
