fix hair fuzz

If the end and control points of a quad, conic, or cubic are the same,
adjust all of them when stretching the curve to account for a square
or round end cap. If all of the points are the same, move all but the
last.

Enlarge the clip check to account for the cap.

The clip bug was detected by ASAN.
