Draw every moving body at the drawn time T = ExactTime + Lead

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).
