/**
 * Which of a map's children belong to the renderer, and which belong to us.
 *
 * The native map view is not a React Native container. On Android it is a real
 * `FrameLayout`, and it lays its children out itself — so an ordinary view
 * handed to it loses the frame the layout engine computed, arrives stretched
 * to the full size of the map, and covers the surface the map is drawn on. A
 * control group written to sit in a corner ends up in the top-left, full
 * bleed, with the map invisible behind it.
 *
 * So the children are split before they are mounted. Anything the renderer
 * understands — a marker, a route, a layer — goes inside it. Everything else,
 * including `Map.Controls` and any chrome written at the call site, is drawn
 * as a sibling above the map, where the layout engine still owns it.
 *
 * Parts opt in by carrying `MAP_LAYER`, so the rule is a property of the part
 * rather than a list kept somewhere else that a new part could be left out of.
