[argyllcms] Re: noise and gamut, input profiles with B2A table

I think it will be right to attach a matrix profile, than convert the image to 
the working space for simple color-independent filters such Blur, Median or 
"Dust and Scratches", may be Despeckle, because in that way the images would be 
processed in native scanner ADC space, in which the noise are forming. On the 
contrary, before the other color-depended filtering the image have to be 
converted in !filter! working space. The space different from the filter 
designed to may produce not excellent results.
