Not aware of anything. As you say, it's pretty much a Firefox-only patch... I don't even know why they bother, since I can't say I've ever seen an APNG file in the wild. Neither IE/Edge or Chrome support the format, so I doubt there are many sites which used them. > AFAIK, the argument was that the libpng folks want the > mng media type to handle all animation stuff, but the Firefox folks > thought that was an overkill and that png should at least be able > to do everything gif does. Thank goodness situations like this are > not very common. MNG has even less support than APNG does... not one of the mainstream browsers can render it. And thinking on it, none of those browsers have *ever* supported it... it was dead before Chrome or Safari appeared on the scene, and was dropped from the Mozilla codebase before Firefox appeared.
