I believe the standard APNG patch is from here: https://sourceforge.net/projects/libpng-apng/ It's needed to build Firefox and you can see it applied in all sorts of Linux distributions, e.g. Linux From Scratch[1], Debian[2], and Arch[3]. 1. https://www.linuxfromscratch.org/blfs/view/svn/general/libpng.html 2. https://sources.debian.org/patches/libpng1.6/1.6.37-3/libpng-1.6.37-apng.patch/ 3. https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=libpng-apng#n21 Best regards, Michael
