RFR: 8318577: Windows Look-and-Feel JProgressBarUI does not render correctly on 2x UI scale

[Prasanta Sadhukhan]

JProgressBar (StringPainted variant) does not render consistently on HiDPI displays (e.g. 200% Scale Factor) on Windows (using Windows Look-and-Feel) depending on the height at which JProgressBar is rendered, in which case the gap between progressbar and skin is different for different height as can be seen below

Native windows progressbar renders without leaving any gap as can be seen here

so the padding is removed to render the progressbar similar to windows native and it is rendered properly
