It is, IMHO. I'm not responsible for incorrect FreeType usage on iOS,
and I really don't know *how* the iOS people call the library.
Consequently, I can only handle bug reports, and I already gave a
diagnosis and how to further proceed.

Given the high resolution screens used on iPhones and iPads, together
with the fact that OS X doesn't use hinting, this is the way to go,
I'd say.

Uh, oh, the mailing lists *are* the ultimative source for FreeType
knowledge! They are prominently announced in FreeType's README file,
they are properly mentioned on the FreeType's `contact' web page –
what can I do more? [Well, I've just added gmane links to
`contact.html' for access via the web.]
What you ask for is advice for a particular font; up to now noone has
ever mentioned hinting problems on iOS.

It's certainly *not* broken. As mentioned repeatedly, I guess that
iOS doesn't use hints at all. Maybe the hints in those system fonts
are for ClearType only, produced by a third-party font developer who
was commissioned to create the fonts, but this is then irrelevant for
iOS.

I've shown you a work-around. For a fix (if there is really something
to fix) I need comparison images.
