Thats the sort of thing I'd like, if functions where 'extended' so that
they passed x,y,z,u,v when rendering a uv mapped object or just u,v.

All this came from a uv_mapped 2D pigment function that I wanted to try
using as iso_function to 'displace' a sphere, to give that extra inch of
realism over using it as a normal function.
