				# Date : 04/08/2005
				# Purpose : Uses the NatureUP1D predicate to select the lines
				# of a given type (among Nature.SILHOUETTE, Nature.CREASE, Nature.SUGGESTIVE_CONTOURS,
				# Nature.BORDERS).
				# The suggestive contours must have been enabled in the
				# options dialog to appear in the View Map.
