| These files contain noise functions that are compatible with all | |
| current versions of GLSL (1.20 and up), and all you need to use them | |
| is provided in the source file. There is no external data, and no | |
| setup procedure. Just cut and paste and call the function. | |
| GLSL has a very rudimentary linker, so some helper functions are | |
| included in several of the files with the same name. If you want to | |
| use more than one of these functions in the same shader, you may run | |
| into problems with redefinition of the functions mod289() and permute(). | |
| If that happens, just delete any superfluous definitions. | |
