WaterProfileCommand

Remarks

What a handle drag commits to. One entry for the whole drag rather than one per pointer move, which is TerrainStrokeCommand's arrangement and its reason: a drag is one thing an author did, and forty entries is an undo stack nobody can walk back through.

⚠ It holds the value before and the value after rather than a delta. A delta applied twice is a profile that drifts, and an undo stack is replayed in both directions — which is exactly when a drift becomes visible and impossible to attribute.
