NovoAtlas

This update backports everything from NovoAtlas 1.8 on 26.2/3 to Minecraft 1.21.1. This includes the following features:

• Added horizontal scaling with nearest_neighbor, bilinear, bicubic, and lanczos interpolation types
• Added a wider range of image formats
• Added fluid height maps
• Added novoatlas:get_preliminary_height_from_map and novoatlas:get_height_from_map density functions (they behave identically to 26.2/3)
  • Related, added a 1.21.1-exclusive novoatlas:initial_density_heightmap density function that works more like novoatlas:heightmap but subtracts the initial elevation by 8. This is used only for the initial_density_without_jaggedness override, and is considered deprecated as newer versions will not include this function.
• Added novoatlas:biome_cell_color_map biome source
  • This allows developers to downscale their biome maps by 4x to save memory
• Added a center_offset field to map info objects.
  • This will adjust where exactly the centre of the map will generate
  • Specified as a list of 2 floats that are in units of the width and height of the map.
• Added a image_wrapping field to map info objects.
  • This specifies how to sample height values beyond the finite bounds of the map.
  • The three available options are clamp_to_edge (default), repeat, and mirrored_repeat.
  • Void will no longer generate beyond the map edge
• Added blend image to random generation
• Added a new example datapack for blend to random image generation
• Increased the transition range of the heightmap density function in image map generators to improve structure blending around blocks high above the surface
• Improved the example datapacks in general
• Fixed heightmaps using 2x more memory than they need
• Fixed villages near water generating underwater
• Fixed aquifer barriers generating near shoreline
