> Original change's description:
> > heif: Add AVIF type and AVIF sniffing
> >
> > AVIF is the image format based on the AV1 video codec. The
> > container for AVIF is very similar to that of HEIF. Add type
> > definitions for AVIF and sniffing code for detecting AVIF images.
> >
> > The underlying android platform's HEIF decoder implementation will
> > also support AVIF decoding.
