I plan to use a combination of Freetype and Harfbuzz for that, but so 
far, I'm just using Freetype.  Essentially, you first use Harfbuzz to 
convert your string into the correct order with the correctly selected 
ligatures, and then you use Freetype to render the individual glyphs.

That's not yet tried, so far, but it's fairly easy, because you only need 
the buffers part of Harfbuzz: https://behdad.github.io/harfbuzz/harfbuzz-
