Uhm, copy of a flat field?
I doubt that is even possible, and if it is, it definitely isn't a sane idea,
we do not even embed ICC color profiles and watermarks, and those
are definitely much smaller than that :)
I was mostly talking about dust removal - analyze image for dust location
and sizes; store those coordinates+radius in params
(that will be something like 3*4 byte * N dust spots, where N can not
be bigger than
some predefined value, because our iop params is a statically-sized
typedef struct)
(note i have no clue how it (dust removal) would actually work,
i'm only stating how it should work if it is to be a proper darktable iop)
