Higher order function. Computes 2D Worley noise using provided distance function. The returned function takes 2 args: position and jitter amount, the latter in [0..1] interval. Returns noise components as vec2, with the x component containing the distance from closest simplex center and y the noise value. The vector components can be used individually or combined (e.g.
noise.y - noise.x)...Based on implementation by Stefan Gustavson: http://webstaff.itn.liu.se/~stegu/GLSL-cellular/GLSL-cellular-notes.pdf
