add this to slaves to account for vertical fov.
this is my shortcut for 16:9 galaxy screens, but really the browser document width and height should be queried and used for this.
var displayAspectRatio = 16/9; // height/width - query dom for this
viewer.camera.frustum.fov = toRadians(CONFIG.slaveHorizFOV * displayAspectRatio);
this will also need to be reset on browser window size change.
