Your link has no information on ANIMATED png. The ANIMATED functionality has no
advisories since 2008...

I have this information -- this was discussed (with your and my selves present)
back in 2008. But we are not going to change the way Mozilla projects are going
about this... Our options at this point are:
* continue building a private libpng as part of each Mozilla application -- a
silly redundancy of patches and waste of time and space;
* make a separate port (apng or mozilla-png) -- making sure, it does not
conflict with the "official" png;
* just turn the APNG option on by default in the existing png port...
I think, the third options is the easiest -- and it has NO downsides... Yours,
