Description
## 3D Annotations
Create a `3DPointAnnotation` that takes a `CLLocation` object at initialization.
3DPointAnnotation(
location: CLLocation(
coordinate: CLLocationCoordinate2D(latitude: 0, longitude: 0),
altitude: 500
))
This `3DPointAnnotation` (or `Line`, or `Polygon`) would be integrated into the rendering of the 3D view. The annotation would respect obstruction caused by terrain. It would have to be considered as dependant on the terrain `exaggeration` property too.
## Why
This feature is valuable for depicting locations that are above ground level, like the 30th floor of a building, or a 3d geometric shape surrounding a meteorological entity, like a hurricane.

Research direction
No files or tests are identified. Start by tracing the existing 3D view rendering and annotation integration, then determine how a CLLocation-backed point, line, or polygon can participate in that pipeline. Done means 3D annotations render above terrain while respecting terrain obstruction and terrain exaggeration.
