//! V1510 (1.13-pre4+6) — schematic-relevant subset of `V1510.java`.
//!
//! Kept:
//!   * BLOCK rename (`RENAMED_BLOCKS`): portal -> nether_portal, the `*_bark`
//!     log ids -> `*_wood`, and `mob_spawner` -> `spawner` (V1510.java:33-50).
//!   * ITEM rename (`RENAMED_ITEMS` = `RENAMED_BLOCKS` + clownfish /
//!     chorus_fruit_popped / two illager spawn eggs) (V1510.java:52-60).
//!   * ENTITY rename (id + ENTITY_NAME): strips a `minecraft:bred_` prefix, then
//!     looks the result up in `RENAMED_ENTITY_IDS` (V1510.java:80-86). Implemented
//!     as a function-style `Renamer`.
//!   * ENTITY `copyWalkers` for each renamed entity id (V1510.java:96-107).
//!
//! VERSION = MCVersions.V1_13_PRE4 + 6 = 1504 + 6 = 1510.
//!
//! Skipped (non-schematic): the RECIPE rename (`RECIPES_UPDATES`,
//! V1510.java:62-71/78) and the STATS rename (V1510.java:88-93).
