UI Background Blur

How it works

1. Apply Blur Effect: The base layer has a blur effect applied to it.
2. Take Snapshot: A snapshot of the blurred base layer is taken and rendered into a sprite called bg. The bg sprite has the same size as the camera.
3. Disable Blur Effect: The blur effect is disabled on the base layer.
4. Mask with NewSprite3: The bg sprite is then masked with NewSprite3.

Static blur

Instead of repeating the above multiple times, its done once.

Dynamic blur

Repeates the steps every 0.055 seconds, which is 18 frames per second. It can be executed every frame.
