referring to the discussion in povray.newusers, i tried to make a pattern
testing if there is something 'above' the evaluated point.

syntax right now is:

pigment {
  project <vector>, object
  [color 1]
  [color 2]
}

I called it 'project', because it's like something being projected on the
object.  Together with megapov's slope pattern it could do what Marc
wanted.

Comments and suggestions welcome of course.
