This method provides the needed information to evaluate media queries. Every feature in Media Queries Level 4 is present, either as code or as a FIXME: https://www.w3.org/TR/mediaqueries-4/#media-descriptor-table There's a draft Level 5 which I have ignored for now. Some are unimplemented for now since we do not have access to the requested information. Some require StyleValue types that we do not yet support. Many are hard-coded for now since we do not (and may never) support monochrome or text-only displays for Browser.
