"..LUT This is a palette image and the value of this key should be a pdl
containg an RGB lookup table (3,x), e.g.
LUT => $lut,.."
I assuming the above means a [3, x] piddle where every row is a 3
element piddle with rgb values.
An associated question -- a n00b such as me comes across documentation
that is not clear... partly that is because I am n00b, and partly
because the documentation is not clear.
If I think up of a potentially better/clearer way to express what the
docs say, along with useful usage example, how should I help update
the docs?
