// - Guarantees correctness if BorderWidth is being used
// - If we were to use RelativeSize/FillMode, we'd need to set the Icon's RelativeSizeAxes directly.
// We can't do this because we would need access to AutoSizeAxes to set it to none.
// Other issues come up along the way too, so it's not a good solution.
