When saying OTF I meant the common convention of naming CFF falvoured
OpenType fonts (3rd order Bezier splines) with a .otf extension and
TrueType flavoured (2nd order) with a .ttf extension. Well, I know it
is a major source of confusion, but the OpenType specification choose
to make our life harder by supporting two contradictory file name
extension schemes!
