A shader that renders hidden (back-faced) lines differently from visible (front) lines.
Polygon offset is used to displace fragments depths a little so that there is no z-fighting in rendering the same geometry multiple times.
Important properties:
frontline: Specifies the color and the width of the front facing lines.
backline: Specifies the color and the width of the back facing lines.
solid: If enabled, the mesh is rendered as usual in addition to the lines. If disabled, only the lines are rendered.
Unit:

Descends from
