	I haven't tried this, but I would expect it to be possible as long as
	the GRASS raster file is uncompressed (r.compress -u) and you have all
	 of the header info from the cellhd directory. Note how many bytes per
	cell are being used in the GRASS file (the "format:" in the header).

	Either a) have the files exported in DLG3 Optional format directly from
	Intergraph, or b) import the dgn file to Arc/Info using the IDGNARC
	command, and then export from A/I to GRASS. Sorry!
