The 24-Bit IFF standard is *not* chunky. It is rather a natural
extension of the ILBM spec to support images up to 24-bitplanes. It
was developed by ASDG - the only thing that was changed in the final
spec due to external input was removal of ASDG's improper usage of
the CMAP chunk for color correction information. A new chunk has been
added for color correction, but the exact name escapes me at the
moment. The latest format can be found on BIX in amiga.dev/iff ...

I'm also not associated with ASDG, but I was at DevCon and I am an
interested party since my company's products support 24-bit image
processing.
