Consider an annulus: there’s a line between the inner and outer circles, avoiding which requires a manual moveto. `ArcPrecise` and `ArcPreciseN` prevent this annoyance by starting, always, with a moveto, never a lineto.

Use PS arc: you (often) have to add moveto.  Use ArcPrecise: you 
(sometimes) have to add lineto.  It seems unimportant.

OTOH, if the goal is to make a better arc, start with lineto instead of 
moveto so programmers have no surprises when they use ArcPrecise.
