Street View depth GoogleStreetViewDepthLoader

Loads the depth map of a panorama: the distance in metres to the planes Google fitted to the scene, with the sky at Infinity. In 360°, the sphere is pushed out to those distances, and the camera sways a little so you can see the parallax. Flat, the depth map is shown below the panorama: hover it to read the distances. Not every panorama has one: those show as a plain sphere.
