PerfectDashTerminal

How a dashed stroke behaves at one end of an open path.

- none — start the pattern exactly at the end. - outset — start half a gap early, so the line begins with a full dash sitting proud of the endpoint. What an arrow's tail wants. - skip — leave the first gap empty, so the stroke starts a dash in. What the end abutting an arrowhead wants, so the dash does not collide with it.
