I also think that this is the right format.

There are two other changes that I'm thinking of doing in this area:

1. Apply the color matrix through lcms.
2. Add a "Linear" output format.

The first is related to Rafael test.c program from a few weeks ago. It
seems that applying the matrix in lcms gives very different results.

Some of the difference is that lcms uses the sRGB gamma function that
has very small linear part. This adds "fog" to the picture, that I
still didn't find how to correct.

There is also a difference in how saturated colors are rendered. lcms
give results that are much more similar to the camera's jpeg. This
makes me think that there is something wrong in the way I apply the
color matrix in UFRaw.

The "Linear" output option is suppose to be the correct way to tell
UFRaw not to apply any transformation.
