Detailed Description

Record of all pixel modifications made to a single tile during mangling.

When a tile is mangled to make it unique, this struct records the exact changes made: which tile was modified and which pixels were changed. This information is needed to backport the changes to the tiles.png image.

Each TileMangleRecord targets a distinct tile_index. No two records share the same tile_index. This invariant is guaranteed by mangle_duplicates, which visits each tile at most once. A record contains one or more pixel changes (single-pixel mangles are most common, but multi-pixel mangles are used as a fallback when single-pixel swaps are insufficient).
