Warp posted this code for a wood floor he made, and I'm mystified by the "2"
after "gradient x".  Can anyone explain?

normal { gradient x 2
    slope_map {
     [0.00 <0, 1>]
     [0.05 <1, 0>]
     [0.95 <1, 0>]
     [1.00 <0,-1>]
     }
    scale 2
    };

It's an optional scaling factor for the bumpiness. (Officially there 
should be a comma between the "x" and the "2", but POV-Ray is rather lax 
on commas.)
