+## Terrain primitive RE

+Primitive layer types:
+0: PrimLayer0
+Stores PrimLayerElement0 { primitive, vb_descriptor, key0, key1 }.
+Sorts by dynamic vertex-buffer descriptor and stream/layout keys,
+then calls primitive->Render in grouped order.
+
+1: PrimLayer1
+Stores PrimLayerElement1 { primitive, distance_key }.
+Inserts by descending distance from sort_origin.
+Calls primitive->Render in stored order.
+
+2: PrimLayer2
+Stores IPrimitive* only.
+Alpha-filters and appends.
+Calls primitive->Render in insertion order.
+
+3: CCamDistSortLayer / PrimLayer3
+Stores PrimLayerElement1 { primitive, distance_key }.
+Inserts by descending distance from sort_origin.
+Does not call primitive->Render; merges primitives into batched dynamic-VB draws.
+
+4: illegal.
+
+5: PrimLayer5
+Same primitive pointer list style as PrimLayer2.
+Renders only when UseReflections is enabled and clears Z before render.
