QTR-Quadtone RIP

Hi Sandy,

A few differences:
GRAY_CURVE only affects the inks under the GRAY defs -- not the TONER defs
It's a simple (X,Y) curve like Photoshop curves.  Any set of (X,Y)'s are
accepted.

LINEARIZATION affects the whole set of inks.
It takes Lab or density values and converts those units into (X,Y) coords.
But they are "inverse" to get a correction curve making the new result
linear in L values.
It only accepts measurements of evenly spaces steps.
