Functions
Array	hmap::non_parametric_sampling (const Array &array, hmap::Vec2< int > patch_shape, uint seed, float error_threshold=0.1f)
	Synthesize a new heightmap based on an input array using a non-parametric sampling method.
Array	hmap::quilting (const std::vector< const Array * > &p_arrays, hmap::Vec2< int > patch_base_shape, hmap::Vec2< int > tiling, float overlap, uint seed, std::vector< Array * > secondary_arrays={}, bool patch_flip=true, bool patch_rotate=true, bool patch_transpose=true, float filter_width_ratio=0.25f)
	Synthesize a new heightmap by stitching together small patches from input heightmaps.

This header file defines functions for synthesizing new heightmaps by using various techniques such as non-parametric sampling, patch quilting, and blending. These functions allow for the generation of larger or modified heightmaps based on input data, using methods like patch stitching and random sampling.

Functions provided:

• non_parametric_sampling: Generates a new heightmap using non-parametric sampling.
• quilting: Synthesizes a new heightmap by stitching patches from a set of input heightmaps.
• quilting_blend: Similar to quilting, but includes blending of patches.
• quilting_expand: Synthesizes a larger heightmap by expanding and stitching patches from an input heightmap.
• quilting_shuffle: Similar to quilting_expand, but reshuffles patches to generate a new heightmap with the same shape.
