True. What I said was that there's no (feasible) way to implement the
function without making triangle meshes. Even the infeasible ways only
work for displacement-along-normal types of maps.

Well, the feature in question is quite powerful and would probably make
it all worthwhile. You know all those nonlinear transforms people are
always asking for, the stretches and bends and twists and morphs and
what-have-you? They're all various kinds of displacement maps. And once
you've added the mesh-generation code to each[1] primitive object, just[2]
add a CSG intersection function that operates on meshes and you can also
have an OpenGL or wireframe preview or a "Create mesh" function like
Polyray has.
[1] Or at least most of them.
[2] "Just." Ha! This is the hard part!
