-// Add Page Visibility API support to old browsers by focus/blur hack.
-//
-// Include this script _before_ Visibility.js.
-//
-// Note, that this hack doesn’t correctly emulate Page Visibility API:
-// when user change focus from browser to another window (browser and your
-// page may stay visible), this hack will decide, that you page is hidden.
-//
-// For Firefox 5–9 it will be better to use MozVisibility hack without
-// this issue. See <https://github.com/private-face/mozvisibility>.
