Not sure. May lighten the skin textures?

Describe the solution you'd like
I was just seeing a video about the new Gabor texture and it feels like it would work very well for texturing skin, as well as wrinkles. Plug it into a tension map, sort out the directions, and we're in business. The default lines texture it generates is very similar to what I was using for wrinkles, when I had time for such things. But even if we don't use it for wrinkles, it might simplify the texture generation for skin and make the shaders a bit lighter?
