This leads me to believe that he's probably uninterested in actually incorporating the APNG patch into libpng. Honestly, I don't understand why the mozilla people have decided to push this APNG standard now. Maybe I'll just go and post into that mozilla issue a complain about wasting development time on an unfinished spec that seems like a reimplementation of MNG. I'll write to Greg (author) and see what he says. This is one of those annoying points in software evolution where big entity A begins spreading around a patched version of Author B's software, which may end up rivaling Author B's implementation of the patch's functionality. --=20 Coleman Kane --=-U/sPS+dzandQ3ccRmaR3 Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAklFnsgACgkQcMSxQcXat5dt8QCfeEwKhgu2MmDQZ3mg6DRXeNqv mmUAn2Oa2R05+zMSvd+LVa830wEvv6+P =ADN2 -----END PGP SIGNATURE----- --=-U/sPS+dzandQ3ccRmaR3--
