performance comparison of ways to find if an array contains a value

Faster way to create new dom elements before insertion

The main difference between these loops is that the second loop increments i mid-loop so it can avoid a subtraction to get the previous element. This is the kind of operation you would do to get an integral image so the array size is set to the same amount of pixels as a 720p image.

Test difference in performance with calc() and var() functions compared with simple units. Test on unitless, percentage and absolute values.
