These are taken from the SRPs, to allow us to use the same\n// texturing library they use. However, since they are not included in the standard pipeline by default, there is no\n// way to include them in and they have to be inlined, since someone could copy this shader onto another machine without\n// Better Shaders installed. Unfortunate, but I'd rather do this and have a nice library for texture sampling instead\n// of the patchy one Unity provides being inlined/emulated in HDRP/URP. Strangely, PSSL and XBoxOne libraries are not\n// included in the standard SRP code, but they are in tons of Unity own projects on the web, so I grabbed them from there.\n\n#if
