-----------------------------+----------------------
When a browser window is resized, a series of intermediate size steps
occurs. The sequence of these resize steps along with a time stamp is
almost certainly unique and can be used link different tabs.
While "onresize" events don't appear to fire in inactive tabs, Javascript
timers work in inactive tabs and can be used to perform very high
resolution polling.
