<i18n dev> RFR: JDK-8303950: [macos]Translucent Windows Flicker on Repaint [v6]

[Jeremy]

> I'm confident about the new test case for this ticket, but the resolution is more invasive than I'd like. (It works, though.)
> 
> In short:
> This introduces a new RenderingHint (in SunHints) to bypass the call in Window to `gg2d.fillRect(0, 0, getWidth(), getHeight());`
> 
> I left more detailed notes here about the proposed resolution:
> https://github.com/openjdk/jdk/commit/1991fdac5dbf76ddaf73cc78a9f7c38370c9674c
> 
> I'm open to suggestions if anyone has a more elegant proposal to prevent the monitor from refreshing too soon?
