Incorrect straight CorridorGeometry

[bagnell]

Copy the below code into Sandcastle. The corridor should be straight along the longitude.

var viewer = new Cesium.Viewer('cesiumContainer', { infoBox : false });
var entities = viewer.entities;

entities.add({
    corridor : {
        positions : Cesium.Cartesian3.fromDegreesArray([

Seems like it wants equidistance, but the original example is. Weird.
