textures-atlas

textures-atlas was a texture atlas initially used to store all block and item textures, and was later used for many other types of textures before being split into a series of other atlases.

textures-atlas, upon first introduction, was a fixed-width 512×512-pixel file that was split into different 16×16-pixel squares for most blocks and items, although flowing liquids used 32×32. The size would later expand to 2048×1024 in its final versions of use.
