Steps to reproduce the problem:
Implement chrome.browserAction.getIcon()

Returns path or ImageData of currently displayed browser_action icon. 

There are cases where Chrome selects the browser_action icon where there is no simple way for extension code to know which icon was selected (eg, based on device pixel density or based on Chrome version (19px? 16px?)). 

This information is useful in cases where extension devs want to match the icon size when calling chrome.browserAction.setIcon()

What is the expected behavior?

What went wrong?
Nothing went wrong. Calm down.
