with IDL enabled in poser 8 and later, the translucence channel causes a posersurface
to emit diffuse light.

 one thing that bothered me about the old gather node - the grainy renders that were
routinely posted here and they may have never explained how to get a smooth diffuse
appearance to it.  I dunno if anybody set IC to 100 (MaxError=0) and maxxed out all
the gather variables to smooth it out, but in those days, poser 6 and the processors were
too slow to waste time trying it.
