Functions
Tensor	hmap::normal_map (const Array &array)
	Generates a normal map from a given 2D array.
Array	hmap::normal_map_to_heightmap (const Tensor &nmap)
	Converts a normal map to a heightmap using direct summation of gradients.
Array	hmap::normal_map_to_heightmap_poisson (const Tensor &nmap, int iterations=500, float omega=1.5f)
	Reconstruct a height/displacement map from a normal map by solving a Poisson equation with Gauss–Seidel iteration.
