Functions
void	hmap::alter_elevation (Array &array, const Cloud &cloud, int ir, float footprint_ratio=1.f, glm::vec2 shift={0.f, 0.f}, glm::vec2 scale={1.f, 1.f})
	Point-wise alteration: locally enforce a new elevation value while maintaining the 'shape' of the heightmap.

	Generate a heightmap from a coarse grid of control points with defined elevation values.
Array	hmap::reverse_midpoint (const Array &array, uint seed, float noise_scale=1.f, float threshold=0.f)
	Apply the reverse midpoint displacement algorithm to the input array.
Array	hmap::ridgelines (glm::ivec2 shape, const std::vector< float > &xr, const std::vector< float > &yr, const std::vector< float > &zr, float slope, float k_smoothing=1.f, float width=0.1f, float vmin=0.f, glm::vec4 bbox={0.f, 1.f, 0.f, 1.f}, const Array *p_noise_x=nullptr, const Array *p_noise_y=nullptr, const Array *p_stretching=nullptr, glm::vec4 bbox_array={0.f, 1.f, 0.f, 1.f})
