function standingWaterIsSampled
universe/src/terrain.ts:553
Whether a body's standing water is sampled into Heightfield.water — a
drainage graph exists — rather than being the one datum a body with a sea
and no graph has. The mesh builder is handed a datum only in the second
case.
Through drains rather than drainageGraph: the streamer asks this once
a patch on the thread that draws, and building the graph to learn whether
there is one is fifty to a hundred milliseconds of stall.
