The array layer coordinate isn't subject to addressing modes like the other coordinates. There's just one selection computation: https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#textures-unnormalized-to-integer This change eliminates the internally used ADDRESSING_LAYER mode, and avoids using the 'w' coordinate as the array layer coordinate for 2D array images (instead exclusively using it for 3D images). Also, the cube face index is combined with the array layer in case of cube array images. The division by 6 was eliminated by adjusting the descriptor 'depth' field instead.
