Two things you could do fairly easily:
	1) turn off normalization (type "0N" (zero capital-N) in the graphics
		window, or select None in the Normalization browser on the
		Obscure panel, or put the command (normalization world none)
		in your ~/.geomview file.)

	   With normalization off, the default view shows approximately
	   a unit sphere centered on the origin, i.e. not too much larger
	   than you want to see.

	2) Use the Ginsu module manually to clip away pieces of the
	   Voronoi diagram beyond the square of interest.
