we need to provide that for cairo developers

Hello, I've seen some messages about adding spot colors (or named color, or Separation and DeviceN in PDF specs terms) some time ago. Or perhaps even adding CMYK as well. Please, does anyone know if there has been any developments in that direction? Is it perhaps planned to include spot colors in the future? Or, is this not very central to the current development?

From time to time, the cairo community sees a message like yours where

we clearly have users interested in these features.

But we haven't had much in the way of concrete API proposals (nor implementations to go along with them!). And it seems that the current set of cairo maintainers do not have the expertise to come up with either of these on their own.

So I think we're going to need some further input from *somebody* before we'll see concrete progress on this front.

Do you know of anyone (perhaps yourself) that could provide some or all of the following:

* Concrete use case to describe what is missing at the application<->cairo boundary.

* A concrete API proposal to satisfy that use case, (and a minimal API that doesn't multiply existing cairo entry points exponentially).

* An implementation of that API.

I'm looking forward to further input here, since I'd love to be able to say that cairo has a good answer for people needing whatever is missing here.
