Please make sure that readers of such an article are made aware of the
/highly/ experimental state of POV-Ray's subsurface scattering feature,
and that syntax /will/ change, probably as the very next step of that
feature's development.

Jim: sure, happy to bundle it up.
Christoph: thanks for your explanation, I see I had it backwards! Artistically I
generally still want to use the SSLT as a color. Specifying how often a photon
of a given wavelength (as an rgb vector) will be scattered will do just that.
Modifying the skin2 settings to eliminate the green and blue photons from
scattering at all (giving us a visible scattering color: red).
#declare sslt_red = <0.63, 0, 0>; // blood color (er, scattering coeficient)
subsurface { sslt_red, <0.013, 0.070, 0.145> }
Much better results than I was getting before!

I just meant with the roughness keyword followed by a higher value than the
current one if any, otherwise higher than the default one.
