constexpr std::uint32_t	wowlib::formats::wdl::WdlVersion18 = 18
	The WDL format version every supported client uses (MVER payload).
constexpr std::size_t	wowlib::formats::wdl::WdlTileSlots = 64 * 64
	The MAOF tile table's slot count: one per map tile of the 64x64 grid, row-major, a zero offset meaning the tile has no heightmap.

	The versions WDL is instantiated (and welded) for: every targeted last-minor-of-major release, in release order.

	WDL: every chunk-set change point (see the file comment).

Detailed Description

WDL version grid and canonicalization pivots.

Everything is chunk presence (carried inline by the members' since()/until() annotations) — the WDL never changed a binary-struct layout:

• TBC adds the per-tile MAHO hole masks (verified: vanilla 1.12 WDLs carry MARE heightmaps with zero MAHO, every 2.4.3 WDL pairs one MAHO per MARE — wowdev.wiki dates MAHO to WotLK, which our client scan disproves);
• legion swaps the object set (MWMO/MWID/MODF give way to the MLDD/MLDX/MLMD/MLMX low-resolution placements — though WMO-only maps keep shipping the old three, so they carry no until()), drops MAOC and adds MAOE;
• BfA adds the per-placement MLDF fade distances and the MLMB byte (both undocumented on wowdev, which had them misdated to Shadowlands — the 8.3.7 fleet survey carries 33 MLDF and 4 MLMB files);
• shadowlands adds the sky-scene chunks (MSSN/MSSC/MSSO/MSSF) and a few undocumented blobs (MLDL/MLDB);
• The War Within adds MSLD/MSLI.
