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.

OK.  That's two (or three?) opinions.  Anyone else?
