[IPOL discuss] ICC color profiles

Please, no!

This would lead to visually different results to visually identical images.

In my opinion, the ICC profile should be treated like a pest, and
stripped from the images at the point they touch the demo server (by
the upload function, if possible).  Even if the user uploads an image
with an ICC, the input images that are shown in the "params" page
should contain no ICC data.  The user may complain that the upladed
image looks different on the web than on his computer, but this is a
minor problem compared to giving different results for images that
look exactly the same.
