Well, a little bit of progress, but something's obviously not right...

Here's what I've got now, with tamrielheightsmall.png being a straight 
height-gradient render.

box{
   <-7200,-4800,-0.1>,< 7200, 4800, 0.1>

   #declare InputPigment = pigment{
     image_pattern{ png "c:\downloads\tamrielheightsmall.png" }
     rotate z*180
     translate <-0.5, -0.5, 0.0>
     scale <1,0.8,1>
   }

   pigment{
     Pg_Elevation_Lines( InputPigment, 8, 2, 32, 0, off )
     pigment_map{ [ 0 InputPigment][ 1 rgb x] }
   }
   finish{ ambient 1 diffuse 0 }
}

...and this is what it comes out as.  (there's some weird noise at the 
top and bottom that's there even with just using InputPigment as the 
pigment, and the contour lines are all noisy)
