Jonas Jenwald 6260fc09a3 Attempt to recover valid format 3 FDSelect data from broken CFF fonts (bug 1146106) ...

According to the CFF specification, see http://partners.adobe.com/public/developer/en/font/5176.CFF.pdf#G3.46884, for `format 3` FDSelect data: "The first range must have a ‘first’ GID of 0".
Since the PDF file (attached in the bug) violates that part of the specification, this patch tries to recover valid FDSelect data to prevent OTS from rejecting the font.
