Planets, belts, wells, loot, mines, stations, the chunk reticle and the flow clock are evaluated through DrawAhead (Time, Orbit, Height, Position) at one drawn time; the rail law lives once in Zone.Offset; OrbitPositionAt, GetHeight, ChunkPose, EvaluateBelt and RideHeight take a time. Fixes the planet jumping against a co-moving ship at display rates above the step rate. Not yet built or run (Unity presenter files are verified by compile only on Starfire).
