[Bf-python] FaceNormals

Hmm. I guess you'd need to test for 4 verts...

if(mv->v[4])
    CalcNormFloat4( mf->v[0].co, mf->v[1].co, mf->v[2].co, mf->v3, fNormal)
        return newVectorObject(fNormal, 4)
else
    CalcNormFloat( mf->v[0].co, mf->v[1].co, mf->v[2].co, fNormal)
        return newVectorObject(fNormal, 3)
