Godot-Acrylic

An effect similar to Microsoft's Acrylic and Mica materials achieved in Godot 4.
It works by getting the wallpaper file and blurring it in the engine. Here's the blurring algorithm.

Limitations

• Implemented on Windows and Linux, but the fallback system is not great.
• Doesn't account for other windows (only blurs the background image)
