Not sure about Rah Guzar, but it squashes bug#54646 for me. Thank you
so very much, Yamamoto Mitsuharu!
With regards to the performance, my eyes say that patch no. 1 (i.e., the
one that patches src/hbfont.c) is slightly faster than patch no. 2 when
I continually zoomed to reproduce bug#54646. The test material was this
random webpage https://www.dinamalar.com/news_detail.asp?id=3117719,
and M-x report-emacs-bug report on the Emacs with the patch is at the
end.
The test that I used is the same as I outlined in bug#54646, namely,
visit that webpage in eww, zoom in and out with C-scroll-wheel. The
glyphs _do not_ bump into each other or get weirdly placed whereas
without the patch, glyphs can be oddly spaced.
