Define a named color?

[erik]

A way to define named colors that, when exported to a pdf, would be recognised as a spot color when imported in InDesign (or similar tools).

Good one. I'm not sure how an NSColor object can be put into a PDF as a spot color. That needs to be figured out first. And then we need to think of a DrawBot API.

this should somehow already work for images: see ImageObject spotColor
