Re: [webrtc-pc] Spec says scaleResolutionDownBy must default to 1, but browsers differ (#2535)

> Yes, the order of deactivation is defined in the simulcast SDP spec, so 4:2:1 is the sensible way (the largest layer will be dropped first).

This assumes that multiple `sendEncodings` means "simulcast". Wrong assumption at implementation level. I may want to send two encodings, both with same resolution (`scaleResolutionDownBy: 1`) and different `maxBitrate`. Ideally I'd like to have per encoding `maxFrameRate` but such a useful setting did never officially land in the spec.

For instance, for screen sharing is much more important to keep the original resolution (even at lower frame rate in lowest simulcast layer) than keeping bitrate by lowering the resolution.
