QTR-Quadtone RIP

I just used the 7880 driver so no I couldn't try orange and green.
Actually selecting
the inks is probably not a big problem but I do have to figure out any
issues with
more than 8 inks.  For instance the inkseparation page uses 8 bits for
ink selection.
I'd probably put this off until later -- who really needs that many
inks for B&W.

I have looked at the 4900 and is apparently all Esc/P2 so should not
be a problem
except for the 8 ink -> 10 ink issues.  Haven't looked at the R3000
but I'd think
its like the R2880 except for the K ink selection.
