feature request: APNG

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Browsing into imagemagick site and archives, I found nothing about
animated PNG, probably because it's a quite recent format (only
supported by - as far as I know - Firefox 3 and Opera).

I thought about writing to this mailing list asking for support for it
(notably, in the "animate" command line tool, but also in rescaling
capabilities) because I believe in the next future it will replace
animated gifs in a lot of cases.

I don't know much about the structure of Image Magick's code, but I
read ([1]) that it is a wrapper around several "delegates", including
libpng: does it mean that new Imagemagick versions have - for instance
(I thought about writing when I noticed Wikipedia's Mediawiki was
unable) - the capability to resize APNGs (since libpng now does
support APNGs)?

What about the possibility to create APNGs? I imagine tools like
animate don't actually know that libpng can create animations, but it
would maybe be trivial to "teach them"? Or would it be interesting to
wrap on an already existing small program ([2]) that converts TGAs to
APNGs?

Excuse me for my poor technic language and knowledge.
