It seems like winit has support for having a blur effect in transparent windows with the following APIs. [Windows Backdrop - Acrylic/Mica](https://docs.rs/winit/latest/x86_64-pc-windows-msvc/winit/platform/windows/trait.WindowAttributesExtWindows.html#tymethod.with_system_backdrop) [Linux Wayland with org_kde_kwin_blur_manager protocol](https://docs.rs/winit/latest/src/winit/window.rs.html#960-963) Couldn't find anything for MacOS as of now 😢 Is it perhaps possible to expose these attributes to Node.js window creation API? I can also work on a PR for this.
