Well, yes, but: Give me a format 2 kerning table, and I'm going to add
support for it immediately.

I'm working on it!

 

  In other words, the current FreeType code doesn't do any harm, AFAICS.

This block is wrong, as in, it should not run if format is not zero:

      /*
       *  Now check whether the pairs in this table are ordered.
       *  We then can use binary search.
       */
