QTR-Quadtone RIP

There are usually multiple ways to do things.  I, like most, probably just
got comfortable with one approach and continue to use it.

For me, 2 points and a line are easy to grasp.  So that is how a draw a
straight line in QTR.

I don't generally use the gamma, shadow and highlight adjustments in QTR.  I
try to limit variables by leaving things at their defaults.  Among other
things, this probably minimizes error.  I also think default settings are
usually the center points of assumptions and compromises that were probably
part of the original design.
