(Meshes only with backface culling, not stand alone tris) This version is meant for 3D, essentially it's a bit more stable and faster than the general-purpose one. Basically really tiny triangles wont mess up sorting and take up performance as much
This is only for dimensions above 2D's use (joke) Ok now I would really recommend using this over rex's filler, you'll actually notice a slight increase in FPS
