/**
 * Cine engine's save game formats.
 * Enumeration entries (Excluding the one used as an error)
 * are sorted according to age (i.e. top one is oldest, last one newest etc).
 *
 * ANIMSIZE_UNKNOWN:
 * - Animation data entry size is unknown (Used as an error).
 *
 * ANIMSIZE_23:
 * - Animation data entry size is 23 bytes.
 * - Used at least by 0.11.0 and 0.11.1 releases of ScummVM.
 * - Introduced in revision 21772, stopped using in revision 31444.
 *
 * ANIMSIZE_30_PTRS_BROKEN:
 * - Animation data entry size is 30 bytes.
 * - Data and mask pointers in the saved structs are always NULL.
 * - Introduced in revision 31453, stopped using in revision 32073.
 *
 * ANIMSIZE_30_PTRS_INTACT:
 * - Animation data entry size is 30 bytes.
 * - Data and mask pointers in the saved structs are intact,
 *   so you can test them for equality or inequality with NULL
 *   but don't try using them for anything else, it won't work.
 * - Introduced in revision 31444, got broken in revision 31453,
 *   got fixed in revision 32073 and used after that.
 *
 * TEMP_OS_FORMAT:
 * - Temporary Operation Stealth savegame format.
 * - NOT backward compatible and NOT to be supported in the future.
 *   This format should ONLY be used during development and abandoned
 *   later in favor of a better format!
