Oh! Our understanding was these functions were deprecated, I will have a 
look.

Our main concern is I don't know what would happen if, for instance, we 
call the shaper from two different threads, given that ft_library is 
static.

/* Thread-safe, lock-free, FT_Library */
static FT_Library ft_library;

Despite the "Thread-safe" comment, we have experienced a lot of problems 
when two threads are using the same FT_library. So I don't understand 
what the "Thread-safe" claim is based on.

Also, do most users rely on hb-ft? Or they usually make their own font 
parsers?

Thanks!
