Multiple listeners on window will cause performance issues about react-dimensions HOT 2 CLOSED

It would be important to test whether this is actually a performance issue first. Updates already get queued up in a single animation frame update. I don't think firing window.onresize has any performance implications e.g. Firing it once vs firing 10 times won't gain anything compared with the repaint cost. Also, from an app design perspective, if possible it would make more sense to wrap an outer component in react-dimensions and pass down the props and calculate widths and heights from them. There is only one browser window so you only need those values once and everything else can be calculated.

Ah I see... I didn't realize it was essentially batched. Now I see it here: https://github.com/digidem/react-dimensions/blob/master/index.jsx#L105-L111

Nevermind then. If we notice a problem we will reopen.
