@stefhak I think you're thinking of "constraining" = rescaling, which is not the spec definition.

For instance, If `getUserMedia` worked that way, `max` and `exact` would be redundant.

The spec defines `applyConstraints()` as a filtering function applied to a *UA-specific* pool of available [settings dictionaries](https://w3c.github.io/mediacapture-main/getusermedia.html#dom-mediastreamtrack-applyconstraints()) (instances of [MediaTrackSettings](https://w3c.github.io/mediacapture-main/getusermedia.html#dom-mediatracksettings)) for a device. A discovery API essentially.

Firefox and Edge implement discrete settings dictionaries. Chrome implements a continuous space.
