I just submitted version 1.1.1 (update: has been approved) which lets you set the width of the rendered line in the inspector. Here is an example, obviously it's over the top, but you can set the width to anything you like.
Now I just need to provide a nice function to pass rendering points to Vectrosity. I'm sure those of you who own a Vectrosity license would like to be able to combine the best of both. I promise when I'm done it will be the last time you'll see me talk about rendering for a while.
