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, -mi
