--------------------------------------------
notes: Your clipping algorithm rejects triangles which have any vertex
lying outside the viewing frustum, even if part of the triangle is still
inside.  You should clip to the plane in that case, producing a new
triangle (or triangles) for the region which is inside.  Also, you avoid
transforming your normals by computing them only after the vertices have
been transformed.  This is great, except that the problem statement still
asks you to provide a method for transforming normals.  Otherwise, your
code looks great.  Good job on the Gouraud shading.
