Camera.getRectangleCameraCoordinates doesn't account for terrain

[hpinkos]

Reported on the forum: https://groups.google.com/forum/?hl=en#!topic/cesium-dev/R7CLnK9PZE8

In this example, the camera zooms to span where the rectangle would be on the WGS84 ellipsoid, which is zoomed in too far for where the rectangle is on the terrain surface.

var viewer = new Cesium.Viewer('cesiumContainer');
viewer.terrainProvider = new Cesium.CesiumTerrainProvider({
     url : '//assets.agi.com/stk-terrain/world'
 });

var west = -45.977340999999605;
var south = -21.417668000000273;
var east = -45.96351400000036;
var north = -21.403251000000008;
var rectangle = new Cesium.Rectangle.fromDegrees(west, south, east, north);
viewer.entities.add({
    rectangle : {
        coordinates: rectangle,
        material: Cesium.Color.RED.withAlpha(0.5)
    }
});

Sandcastle.addToolbarButton('Set View', function() {
    viewer.camera.setView({
            destination: rectangle                     
    }); 
});

@ggetz I need to point the camera at a Rectangle on terrain
Now scene.globe.getHeight doesn't take terrain into account and because of this the camera can go under the ground
