While bozo, spotted, and bumps simply call Noise(), the function for 
dents seems to just return the cube of Noise().(I really don't see how 
this could be useful when poly_wave and bozo(or bumps, or spotted) could 
give the same result...I assume it comes from a version which didn't 
have pattern waveforms yet)
Probably the reason it appears to not have any plateaus is the way it 
curves near the edge of the plateau. The action of cubing the value 
might make it curve so the flat area is almost indistinguishable.
