Well, now that's a surprise. The post-alpha of Opera 9.5 actually supports APNG 1.0.

MNG was supported in some nighty builds many moons ago, but it never went into a stable release. The MNG specs are sort of complex and the lib was too big. The growth of the executable couldn't be really justified with this little feature. Especially since most browsers don't support MNG at all and therefore it isn't used anywhere.
