I can't seem to figure out how to change the intensity of normal surfaces
from the pov documentation. i.e how far a normal surface portrudes from the
regular surface of an object.

How do I change how far the checker lines extend beyond the 2 unit radius of
the sphere?

Is there any to also change the width of the lines (i.e) thicker lines, but
keeeping the area of each square relatively the same?
