When used as a pigment, bumps, dents, and bozo all directly call noise3d, so
they are identical.

Not quite...the dents pigment pattern is the result of Noise() cubed.
The patterns which directly call Noise() and do not modify it are bozo,
bumps, and spotted.

How difficult would it be to have it use the built-in function if no
slope_map is specified, but to use the second evaluation method if one
is specified? I don't know that area of the code very well...
