QTR-Quadtone RIP

Hi Steve,

It's not hard to add a little color ink to the 3MK setup.  Look at the regular
R1800-UC curves -- there's a black-only and a couple others -- cool and sepia.
They show using 2 color inks on top of black-only.  Do a similar thing with the
3MK curves and you can add whatever you like in tone.

Use the ink limits to adjust how much color ink you want.  I'm guessing that
you can keep the existing linearization if the amount of color is not a lot.
