Re: [mediacapture-screen-share] Handle source device pixel ratio

Most of the web treats high DPR displays as though they were downscaled anyway.

Maybe a smart UA could remember that the track has a non-unity DPR and apply the scaling as it encodes, unless there are settings applies that might indicate that the raw bits are desired (min-width or min-height greater than the downscaled size, etc...).  That is, we don't have to erase the extra information as it goes into the pipe, we can just keep in until it pops out somewhere that might not want it.  For instance, media recording might still use the higher ratio, as would a canvas or <video> element, but RTCPeerConnection would probably not.
