Link line extending up to arrowhead tip

If you look at the GoJS samples which include pointy arrowheads, and zoom in a lot to see the arrowhead tip close-up, then in most cases you can see the link line extending up to the arrowhead tip. So you don’t get a crisp, sharp tip. For example, try zooming into an arrowhead for the [Minimal GoJS sample][1].

This is not always the case. For example, the [Multi-node path links sample][2] has arrowheads with perfect, sharp tips.

Is it possible to get sharp arrowhead tips for all types of arrowheaded link?

Thanks,
Robert

Yes, as you can see in that Multi-Node Path Link sample, you need to set http://gojs.net/latest/api/symbols/Link.html#toShortLength.
