Not getting rounded corners on Tron skin

[IngwiePhoenix]

I am using the draw method from the demo index.html file in order to have a working Tron skin. However, it does not give me the rounded corners that the displayed Tron skin has. What other things do I have to add to get that working?

add in the override draw function in index.html this this.g.lineCap = this.lineCap;
