Following on bug 1179084 but for screen-capture tracks. We should cover the subset of https://w3c.github.io/mediacapture-screen-share/#constrainable-properties we currently support. Screen capture back-ends don't really have "capabilities" the same way cameras do, so this is mostly filling in some rudimentary information as detailed in the link above. Currently our getCapabilities code isn't aware of this so it goes all the way down to https://searchfox.org/mozilla-central/rev/fa5b44a4ea5c98b6a15f39638ea4cd04dc271f3d/dom/media/systemservices/video_engine/desktop_device_info.cc#354,361 STR: 1. Open https://jsfiddle.net/jib1/rs16kgqd/ Expected result (Chrome): ``` Go! getCapabilities(): {"max":2992,"min":1}x{"max":1934,"min":1}x{"max":30,"min":0} getSettings(): 2992x1934x30 videoWidth/Height: 2992x1934 ``` Actual results: ``` getCapabilities(): undefinedxundefinedxundefined getSettings(): 2992x1934x30 videoWidth/Height: 2992x1934 ```
