The function image style always described as "from Point to ..."
[insert Picture, Bitmap, Texture...] is also inherently higher order.

Examples are Conal Elliott's Pan, Jerzy Karczmarczuk's Clastic and
Peter Henderson's images.

In Clastic and Pan, the higher order image seems like a characteristic
function extended to generate a colour rather than a boolean test, in
Peter Henderson's work (I think) the images are always described with
vectors displacing an initial point and so have similarities to the
"coordinate free style" of graphics pioneered by Tony DeRose and
