I got most of what I needed by setting Custom DPI Setting in Settings -> Appearance -> Fonts -> DPI.
The main pain point that I've had is that Google Chrome doesn't support HiDPI very well. I've manually adjusted the zoom level which mostly compensates almost everything except the buttons on the toolbar, but that's a problem which is independent of the desktop environment, and won't be fixed until Aura support for Linux arrives.  https://code.google.com/p/chromium/issues/detail?id=143619 So that's my experience with Xfce and HiDPI displays; at least for this hacker, it was orders of magnitude less painful than dealing with GNOME. :-)
