Feature suggestion: colour gradient

[TomHartleyYork]

I find these images hypnotic. I would like to see one composed of shapes with an RGB colour gradient fill. In many cases one shape (e.g., rectangle) with a gradient fill could outperform many single colour shapes.

So fewer parameters needed to fit the same image.

seems like an ideal candidate for replacing lots of primitives with a gradient across a primitive.

And in this example image, doing background segmentation might make the gradient be a single primitive (box) and a gradient with a small list of values.
