Hatching Shader

I was troubleshooting some shader problems on the Unity forums, and ended up overhelping and making a pretty decent-looking crosshatching shader (if I do say so myself). Here's what it looks like:

The UV math is a little messed up, but I think it looks pretty cool :D.

---edit---

(can't stop. won't stop) I went ahead and fixed the uv math. It now uses the UVs of MainTex rather than of Hatch0 as it's main input. I was going to resolve (read: "re - solve" as in "solve again") all of the other UVs separately, but it made the inputs a pain to set up when making a new material, so I just left the Hatch Density input.
