lineWidth = 0 actually does nothing.

Since context.lineWidth doesn't take 0

Can you explain more about where and why this is a problem? Do you mean you can't disable body outlines because of this?

[codeclown]

Yes, that is the issue. Can't disable body outline. This goes against the documentation.

Could be easily fixed by simply checking for 0 here.

if(constraint.render.lineWidth) {
    c.lineWidth = constraint.render.lineWidth;
    c.strokeStyle = constraint.render.strokeStyle;
    c.stroke();
}

I'm happy to provide a pull request if you'd like.

@liabru

A value of 0 means no outline will be rendered.

This isn't currently possible to do. @codeclown that would do the trick.
