gif-1.0.tgz ??

[Sean Hinde]

I have been playing with the gif-1.0 contrib and it works quite nicely.
There ain't a lot of error checking in the C code but it works well enough
and is easy to modify.

I've also nearly got Scott's edtk version running. Just some final couple of
gremlins getting all the supporting libs to compile cleanly..

Anyway, here's to June when the dreaded LZW patent runs out - I'd guess the
libgd author will celebrate with a big bang launch of gif support - it is
not as though he doesn't have the code, as he is the same guy who wrote the
one in Joe's contrib :)

If anyone wishes to send me their nearly complete Erlang version though I'm
happy to spend a little time digging around to see if I can add anything to
the party.
