After he struggled to do it programmatically using the drawing primitives provided, I suggested he just overlay a graphic on the screen. That would be much easier to implement.
So off he went. He fired up Photoshop. And fiddled. And tweaked. And fiddled some more.

Presumably an experienced graphic artist could knock one up in two minutes. But after almost an hour of drawing, cutting, compositing, and rearranging, he still didn’t have a convincing rounded arrow.
