Of course.  Many thanks to Philip Laven for making the output of his Mie theory
program available.

Clever way to do it, and yes, that's slow!
Are you using no_image for your shadow-casting object?

I'm also curious why "the wrong way" works, and I can't create a good shadow as
shown by the scattering media documentation page.  Do we not see shadows when
the camera is in line with the light source?

Might need to do an animation of a light source revolving around a ring of
columns . . .
