There was a problem hiding this comment.
even better: while(lastptdef > firstptdef && ... would skip this second loop altogether in the failing case.
BTW do we need this pos = pos.concat... thing at all? Can't we just do lineOptions.positions = srcPos.slice(...)? It's needed in the fill section below but I don't see why it'd be needed here. In fact, even that slice seems like it could be omitted when we didn't drop any points on either end.
