Quite by accident, after posting the query, I found an example of
drawing level curves ("lifted contours") on the graph of a surface:

  Stan Wagon, Mathematica in Action, 2 ed., Springer-TELOS, 1999, sec.
4.5.

But there's nothing there about putting constant-x or constant-y slices
onto the surface.  That will evidently take some work, since what Wagon
does directly uses ContourPlot, and there's nothing comparable for other
slices.
