The JNG container is encoded or decoded in coders/png.c and using some
low-level functions in libpng (for encoding and decoding "chunks").

The embedded main JPEG image and JDAA alpha "image" is encoded or
decoded in coders/jpeg.c using libjpeg.

The embedded alpha channel, when conveyed in the PNG IDAT chunk, is
encoded or decoded in coders/png.c using libpng.
