Phase N.1 step 1: WbSceneryAdapter.BuildTerrainEntries converts our
LandBlock dat type into the TerrainEntry[81] shape WorldBuilder's
TerrainUtils / SceneryRenderManager consume.
Field mapping (TerrainInfo → TerrainEntry):
TerrainInfo.Road (bits 0-1) → TerrainEntry.Road
TerrainInfo.Type (bits 2-6) → TerrainEntry.Type
TerrainInfo.Scenery (bits 11-15) → TerrainEntry.Scenery
LandBlock.Height[i] → TerrainEntry.Height
The spec listed the texture property as 'Texture' but TerrainEntry's
actual property is named 'Type' (confirmed from source). The spec also
described LandBlock.Terrain as ushort[81] but it is TerrainInfo[81] —
DatReaderWriter already decodes the bit fields so the adapter uses
TerrainInfo's named properties rather than raw bit-shift expressions.
