Detailed Description

Batch coordinate->screen projector for the GeoMap 2D overlay. Mirrors GeoMapItem's own single-point camera-reactive projection (GeoMapItem::_updatePosition), batched over N points: projects coordinates through the camera whenever the camera pose, scene anchor, or (in ClampToGround mode) terrain heights change, and republishes the result as screenPoints. Meant for QtQuick.Shapes-based polygon/polyline overlays (survey area, transect lines, landing approach lines, ...) that need many vertices reprojected reactively without each caller hand-wiring its own camera Connections.
