This doesn't actually require CMYK support in the application. If I
understand correctly, GIMP should be able to do this when the colour
management support is integrated, without needing to understand the CMYK
color format. IIRC LittleCMS should be able to take care of issues
involving the output profile, and feed RGB data to GIMP. I could easily
be wrong here, but that's my understanding.
