If width and height are multiples of cell_size, the image will tessellate.
Normally, output pixels are VipsBandFormat in the range
[-1, +1]. Set uchar to output a uchar image with pixels in [0, 255].
::: tip “Optional arguments”
* cell_size: gint, size of Perlin cells
* uchar: gboolean, output a uchar image
