[cairo] Creating CMYK and spot colors using Postscript backend

[Markus Meyer]

Hi,

I'm using Cairo to create Postscript (EPS file) graphics and so far it
works great! However, I cannot seem to find a way to output CMYK or spot
colors instead of RGB colors. I know that full color management (as in
ICC profiles etc.) is probably way beyond the scope of Cairo, but I'd be
happy if there would be a simple user-defined table mapping RGB colors
to CMYK/spot colors or something like that.

What would it take to implement this? Or is this already possible with
Cairo?
