    Class PointEntity

    PointEntity – Interactive, selectable point entity for Cesium 3D scenes.

    Extends Entity; manages appearance, interactivity (mouse/drag), selection, color/highlight, and event callback logic for movement and placement. Supports mouse drag to set position, hover, color, and custom callbacks.

    Parent application reference.

    Initial position.

    Size (px) of the point marker.

    Main color.

    Offset above surface.

    Is this point interactively selectable/draggable?

    If true, point responds dynamically to underlying changes.

    If true, point can be deleted.

    Hide marker while dragging/holding.

    Offset for display tweak.

    Color when highlighted (optional).

    onMove(callback) - Register callback, fired on point move.

    onSet(callback[, once]) - Register callback for when point is set/fixed, optionally fires only once.

    destroy() - Removes event listeners, Cesium entities, and cleans up resources.

    const point = new PointEntity(app, {position: Cesium.Cartesian3.fromDegrees(8, 51)});
    point.onMove(p => console.log('Moved to', p.position));
    point.onSet(p => alert('Point placed!'));
    point.selectable = true; // enable interaction
