[Gdal-dev] converting from NAD 83 to NAD 83 HARN

Hi

I'm trying to reproject an image from "Arizona Central State Plane NAD 83" to "Arizona Central State Plane NAD 83 HARN".  This should shift the image by (X=-0.100, Y=0.182) meters according to http://www.ngs.noaa.gov/cgi-bin/nadcon2.prl.  PROJ4 does not seem to be applying the shift.

Does PROJ4 support HARN corrections?

I have the "normal" NADCOM grid shift files installed and a 2005-04-25 snapshot of GDAL. 

Thanks,
-john
