[Radiance-general] optics2rad

[Mike Martinez]

Law of the universe - once you decide to email the list, you'll figure it
out, and it will likely be a rookie mistake.

The outside pane of glass was flipped in Optics, and the low-e coating was
on surface 1. optics2rad didn't like that, and thankfully refused to make a
bad material description.
