This is a manually-rebased version of D145169, but with the protocol header regenerated, various fixes and tweaks. In particular we only check the pref once when asking for the protocol now, the rest falls through from current_fractional_scale being 0.0. I gave it a shot on KWin and stuff seems to work properly, but let's keep it disabled by default for now and maybe enable on a separate bug. Depends on D186198 Differential Revision: https://phabricator.services.mozilla.com/D186199
