What about the third case?

Rounding to the nearest integer can create unintended aspect changes. Consider:
```js
await sender.setParameters({encodings: [
{ rid: "high" }, // 320x240
{ rid: "medium", scaleResolutionDownBy: 2 }, // 160x120 (320*120 - 160*240 = 0)
{ rid: "low", scaleResolutionDownBy: 3 }, // 107x80 (320*80 - 107*240 = -80)
]});
```
