I think  Dan was looking for options already present in older versions
of gnuplot so that he could produce Octave scripts that did not require
bleeding edge gnuplot support.   

But yes, if we teach the hidden3d code how to deal with a mesh that is not
actually a solid surface, that would be a logical syntax hook to attach it to.
I don't actually know how to do that, so it's pretty hypothetical at this point.
