[Window] Add ability to set rounded corners on an undecorated Aurora window

In Windows 11, rounded corners for windows were introduced. Of course, with an undecorated window and the nature of Java being cross-platform, it does not inherit this functionality from the operating system.

Therefore, it would be good if, for example, there was the ability to make the corners rounded, or have the corners automatically round when on Windows 11. I imagine this could be done by allowing the window to have a certain shape (of which RoundedRectangle() could be passed) or through a parameter of roundedCorners = true. Hopefully, this would then make Aurora applications feel more native for Windows 11 whilst maintaining cross-platform functionality.

Thanks. If you experiment with integrating these two projects together, please let me know if you run into anything that is blocking you on the Aurora side of things.

If an interested third-party wants to provide native integration for windows-level features (such as, let’s say, snap layouts on Windows 11), I will consider providing support in Aurora for configuring Aurora-provided title pane with such integration points. But I will not be in the business of chasing short term fads from OS vendors.

Following this, could there potentially be a future integration of Aurora with Compose Window Styler?
