This scene file looks different depending on whether you use official 
POV-Ray or UberPOV:

}
-----------------------[END CODE]-----------------------

Image uberhills-v36.jpg was rendered with POV-Ray 3.6.1.

Image uberhills-v37.jpg was rendered with POV-Ray 3.7.0.0.

Image uberhills-uber.jpg was rendered with UberPOV 1.37.1.0-beta.10.

When I tried using a regular (non-pigment) function, there was no 
difference between UberPOV and official POV-Ray.  I am running openSUSE 
13.2 (GNU/Linux) on an Intel Core i7 (quad core).
