Umm, it's a little more than that, but facing the faces is a very
important part. Basically, I meant:
1. All polygons wound correctly
2. All subfile references clean
Good point about primitives not being solid. I don't think a renderer
can/should ever assume that a single DAT file describes a solid object.
