Inverted-Hull Stencil Outline Shader

In the title Isolated Intelligence, requirements detailed a simple Outline Effect shader, and after a significant amount of research, I produced this shader which generates the desired effect.

More modern techniques are certainly present, and the inverted-hull method does have significant drawbacks, especially for nonuniform or very thin geometry. Ben Golus goes into extensive detail about advantages and optimizations in this article for medium, which I highly recommend.
