Koch Fractal node

Generates an koch curve similar to ice fractal shape based on input UV at the size specified by inputs width and height. The generated shape can be offset or tiled by connecting a TilingAndOffset node. Note that in order to preserve the ability to offset the shape within the UV space the shape will not automatically repeat if tiled. To achieve a repeating effect first connect your TilingAndOffset output through a Fract node.
