The clutter macro is supposed to place the spheres and cones on top of 
the mesh terrain. Instead, it is placing them all at y = 0. I assumed it 
was an issue with `trace`, but this appears not to be the case according 
to my tests.

The problem does _not_ occur with the test isosurface or the test 
heightfield. I assumed it was a mesh or mesh2 issue, but it is likely 
something else. But what?
