<br>
I was looking into Firefox’s code to check how they handle vertical text<br>
(to see why they get better results for the same font than my code), and<br>
noticed that they try to use vertical presentation forms [1] when the<br>
font lacks ‘vert’ feature [2]. I was wondering if this is something<br>
HarfBuzz should be doing instead?<br>
