ScreenSpaceCameraController.minimumZoomDistance default is incorrect

If you look at the code you'll see the actual default and the default in the doc are different. We should make them match.

I'm not sure what the correct value is. I've noticed that the value of 1.0 causes issues when you can zoom through terrain if you are zooming in to a mountain.

        /**
         * The minimum magnitude, in meters, of the camera position when zooming. Defaults to 20.0.
         * @type {Number}
         * @default 20.0
         */
        this.minimumZoomDistance = 1.0;

@bagnell do you know which is correct?

[bagnell]

1.0 is correct. It used to be 20.0 to prevent the camera from clipping terrain in certain situations.

Unfortunately, @tfili found this because the camera is clipping terrain in certain situations 😈
