//! The 11 three-subset partition patterns shared by ASTC and BC7.

/// For each of the 11 three-subset partitions, the subset index (0, 1, or 2) of
/// every texel in raster order. Block unpacking selects a row by the decoded
/// `common_pattern`, both to locate per-subset anchor texels during weight
/// decode and to assign each texel to its subset when reconstructing pixels.
