/**
* @function
* @memberof Popper.Utils
* @argument {Object} data - The data object generated by `update` method
* @argument {Boolean} shouldRound - If the offsets should be rounded at all
* @returns {Object} The popper's position offsets rounded
*
* The tale of pixel-perfect positioning. It's still not 100% perfect, but as
* good as it can be within reason.
* Discussion here: https://github.com/FezVrasta/popper.js/pull/715
*
* Low DPI screens cause a popper to be blurry if not using full pixels (Safari
* as well on High DPI screens).
*
* Firefox prefers no rounding for positioning and does not have blurriness on
* high DPI screens.
*
* Only horizontal placement and left/right values need to be considered.
