[fluxus] (build-polygons) and normals

[Claude Heiland-Allen]

Hi all, again,

I answered my own question, see attached - tetrahedron of equal 
brightness to (build-cube).  Took a lot of experimenting to get the 
right combinations of values with a lot of help from (hint-normal).  I'm 
wondering why (recalc-normals) didn't come up with the same result...
