In bug 1208636 we added a pref to increase the displayport size on high-memory systems when panning fast. However it seems to cause some jank (see bug 1193969 comment 10, bug 1229929) and bad behaviour, so I think we should disable it for now. Once we have the checkerboarding metrics in place (bug 1226826) and can effectively see how much this helps, we can consider re-enabling it. (Note that this isn't a backout, it'll keep the code, just set the prefs default to zero).
