[HarfBuzz] Beginner question: What are cluster levels?

[Jamie Dale]

I actually just wrote something to give me very similar information since I
realised that my basic "this is a ligature" flag wasn't enough data, so
each of my glyphs now contains the number of characters that the glyph was
composed from. This, along with the cluster index of the glyph from the
source text, and the reading direction of the glyph, allow me to work out
which characters formed the glyph.
