[Breaking change] default shadow blur value should be 0 (and not 1px)

[KimDal-hyeong]

The default value of blur in addInnerShadow is 1.
Therefore, there is a problem that blur is applied.

two solutions.

The first is to add blur: 0 in code of one-side border.

if (borderTopWidthFloat !== 0) {
    style.addInnerShadow({color: borderTopColor, offsetY: borderTopWidthFloat, blur: 0});
}

Or, if blur's default has no reason. We can change it to 0.

addInnerShadow({color = '#000', blur = 0, offsetX = 0, offsetY = 0, spread = 0}) {
...

What do you think about this?

Good catch! I fixed it using your first suggestion:

However, I have no idea why blur=1 is the default. We should change it to 0 (for both inner and outer shadow). It will be a breaking change, but IMO current default doesn't make much sense.
