This commit fixes shading issues in the demo scene due to incorrect
"smooth" normals in the pedestal and unbroken wall.
The original models had non-orthogonal normals which caused the lighting
calculations to assume that the pedestal was meant to be an organic
shape along the edge between tops and sides. I did leave correctly
smooth normals around the cylindrical faces where appropriate.
