Yes, I understand. My problem is that I don't know what to look for, honestly. I haven't used the NSFontDescriptor API much and I don't know the first thing about Emacs internals. The slowness or tedium is not my biggest worry.

But I will try what you suggest, and report how it goes and/or show suspect bits here.
