Normalizing Apple-specific CgBI-fried PNG files. Originally by jongware.

Some more details on CgBI can be found here: https://theapplewiki.com/wiki/PNG_CgBI_Format

Note that this repo is created as an archive.

This code does not depend on any external libraries, so compiling is as easy as this:

$ cc pngdefry.c

Note that you need to compile only pngdefry.c, because it includes miniz.c.
