Hi!

I have [this example](https://codesandbox.io/s/orthographic-zoom-limit-07u1v?file=/src/index.js) which uses TrackballControls and OrthographicCamera. Currently I’m trying to set zoom limits using maxDistance and minDistance, which looks like

```javascript
control.minDistance = 200
control.maxDistance = 300

```

However these values seem to be ignored for OrthographicCameras as the cube continues to be able to be zoomed to 0 or infinity. Is there anything else I can try?

Looking at the source code it seems both properties only work for perspective cameras.

Would it be possible for you to switch to `OrbitControls`? This class supports what you are looking for via its [minZoom](https://threejs.org/docs/index.html#examples/en/controls/OrbitControls.minZoom) and [maxZoom](https://threejs.org/docs/index.html#examples/en/controls/OrbitControls.maxZoom) properties.

Unfortunately my use case requires the ability to spin a mesh 360 degrees around all three axes using `OrthographicCamera`, so I’d need to stick with `TrackballControls`.

Is there a plan to get `TrackballControls` to support zoom limits for `OrthographicCamera`? If so, I can go log an issue in the repo.

[minZoom](https://threejs.org/docs/#examples/en/controls/TrackballControls.minZoom) and [maxZoom](https://threejs.org/docs/#examples/en/controls/TrackballControls.maxZoom) have been added to the `trackballControls`.
