ok, I figured out how to bend the curves in a precise way. Now the brows have that little swoop to them.
There are controls to tilt the hairs left and right, and also curve left and right.
The controls are for the inner and outer ends of the eyebrows, with everything in between interpolating.

The node isn't fully featured. But for what it can do, it does it precisely and cleanly. So I'm happy with it.
