Tom. We're discussing how to process large JPEGs in limited RAM, and
how to deal with the nasty error-reporting mechanism that libjpeg has.
I don't see how pnglite is going to help with that.
Anyway, having looked at it, it seems that it decodes the whole image
in one call into a contiguous memory region. So if I were trying to
decode PNGs then it would require that I had enough RAM to store the
whole decoded image, which is exactly what I don't have. It also
doesn't handle indexed images. It does have sane error reporting though.
