Fix the zoom always return true

[kmvan]

const widthThreshold = window.outerWidth - window.innerWidth * window.devicePixelRatio > threshold
const heightThreshold = window.outerHeight - window.innerHeight * window.devicePixelRatio > threshold

//yes, just add `* window.devicePixelRatio`

Can you elaborate?

[kmvan]

yes.
Tested in chrome.
If the resolution is 1920*1080, the outerWidth is 1920.
If the zoom is 100%, the innerWidth is 1920/1 = 1920.
If the zoom is 150%, the innerWidth is 1920/1.5 = 1280.
...
So, just make the innerWidth "set" to 1:1 range, the bug fixed.

Ok, cool. Can you do a pull request?

[kmvan]

You add it, I'm lazy :)

While this prevents zooming causing false positive, it seems to prevent the detection from working at all. Tested in Chrome 54.0.2840.59 beta.

Resolved a different way in #27 (with caveat that zooming while inspector is open produces false negative)
