STLF, or Stamped Textured Line Fill is an alternative to the STTF triangle stamp youve probably already seen. Instead of using 3 coordinates and using whirl + fisheye this just uses fisheye to create a line stamp with textures. There are some issues with this if you set the size small enough, but I think its fine cause youll rarely see a line thats very long and thin anyway
Mostly everything by me, the math was done by @Chrome_Cat
