Code review comment for lp:~unity-team/unity8/stagedFullscreen.form-factor

So, given this is quite temporary, and we don't have a chance to come up with the proper things at this point, I'd suggest to move the repeater into Shell.qml and determine the form factor from Shell.useScenario. That way we only have to add temporary code (and please add a FIXME comment) to 1 place instead of distributing it over 4 files.

If the screens api allows us to do so, try setting the form factor only to the screen in use, instead of all screens. If not, don't bother, this will do for now.
