Default WebGL line thickness

Is there anyway to change the line thickness default value?

I know that unfortunately there isn't any method to change the line specifications dynamically. Only color can be changed. But if someone knows where the line thickness is specified, it would be very helpful.

No file, test, or entry point is named in the issue. Start by locating the WebGL line-rendering code and the default thickness setting, then determine whether that value can be changed; done means documenting or implementing the requested default thickness behavior and verifying the rendered lines.
