@param displacement The displacement value of the Voronoi cells.
This noise module assigns each Voronoi cell with a random constant
value from a coherent-noise function. The <i>displacement
value</i> controls the range of random values to assign to each
cell. The range of random values is +/- the displacement value.
Sets the displacement value of the Voronoi cells.
