//! The 19 partition patterns common to 2-subset ASTC and 3-subset BC7.

/// For each pattern, the ASTC subset index (0 or 1) of every texel in raster
/// order. The UASTC unpacker selects a row by `common_pattern` for mode 7
/// blocks, whose two-subset ASTC partition must also be expressible as a
/// 3-subset BC7 pattern.
