Offset terrain in WRF Polar Stereographic

Hi,

I thought this problem had been resolved ages ago, but maybe only for
Lambert projections.

I'm using NCL 5.1.1 on WRF v3.1.1 netCDF output with polar stereographic
projection, and I'm running into the same old terrain-offset issues that
some of us have mentioned over the past several years.

Am I correct in my expectations that the WRF NCL mapping routines "should"
handle this these days? Or, am I possibly missing something key? I can go
back and handle this the old way, using the standard NCL plotting functions
I once used, with the following sorts of resource settings

  res@gsnAddCyclic = False ; Regional data, not cyclic
  res@tfDoNDCOverlay = False ; Set True for native
projection

  ; Specify map boundaries
  res@mpLimitMode = "Corners" ; Use the corners limit mode

and not using all those convenient WRF functions, but now I'm wondering...
