--- This node has a normal map which corresponds to a pyramid with sides tilted
--- by an angle of 45°, i.e. the normal map contains four vectors which point
--- diagonally away from the surface (e.g. (0.7, 0.7, 0)),
--- and the heights in the height map linearly increase towards the centre,
--- so that the surface corresponds to a simple pyramid.
--- The node can help to determine if e.g. tangent space transformations work
--- correctly.
