[Radiance-general] filtering normal information from an obj

[Gregory J. Ward]

Hi Lars,

You can try it, but if your purpose is to reduce rendering times, I  
don't expect you'll see much difference from taking the surface  
normals away.  The implementation of normal interpolation in Radiance  
meshes is fairly efficient.

I also wrote a utility for manipulating .OBJ files (a bit), but it  
was written under contract with someone else and depends on some  
other code I developed that isn't part of Radiance.  I could  
distribute binaries, but compiling under multiple architectures is  
beyond my abilities right now.
