  Non - rgbf 1 pigment only applied to surface.

Suppose you take a pigment pattern and use a color map with one color, the other
being clear.   Texture a box with that.   Only the sides of the box are
textured, so it appears hollow.   This makes some sense due to POV-Ray only
raytracing surfaces, however since the rays obviously travel through the box to
the other faces and beyond, I wonder what it would take to have the rays
"detect" and pigment the first non rgbf 1 region.

Testing this with pigment {spherical}, one might naively assume to see the
sphere - but only if you make the edge of the textured box intersect somewhere
less than 1.
