Just like keybindings and the message tray pointer barrier, gestures don't always make sense - for instance, swiping up the screen shield should not trigger the message tray just as the SelectArea action around the left edge should not open the overview. To avoid this, restrict gestures based on the current keybinding mode. https://bugzilla.gnome.org/show_bug.cgi?id=740237
