[HarfBuzz] Harfbuzz features and layout

[Edu García]

Thank you for both of your responses.

Steven: Thank you for the article! However, I'm still a bit confused,
sorry. According to the article, Pango is not a good fit for web browsers
or word processors. So I'm assuming my usecase (render text in this box and
split it in lines) falls into that category? So that means I can't use
Pango either? Sorry if this is obvious, but I'm having a hard time finding
exactly what I need :).

Konstantin: according to Behdah "State of Text Rendering", "HarfBuzz, as an
OpenType Layout engine, is where all the magic happens". And I also see a
header called "hb-ot-layout.h", that I'm assuming is where the Freetype 2
OpenType layout code moved, whatever that means, so that's where my
confusion started.

Again, thank you for your responses!
