histogram filters zero-values, check if this is intended or change

in histogram_view.js
value > 0 ? (Math.log(value) / Math.log(maxValue)) * canvasHeight : 0

I just checked why there is a > comparison instead of >=. The reason is pretty simple: The logarithm of 0 equals - infinity. Therefore this check is correct. Maybe a comment would be helpful to clarify this :).
