How to hide a face (moving not still)

@Namna

Put in order:
Mask: Simple shape (with an ellipse)
The filter you want for the effect (e.g. Gaussian Blur)
Mask: Apply

Ah, so THAT is how Mask: Apply works.
Thank you, @Namna!

I still, however, think an Invert on Mask: Simple Shape would be simpler for may tasks. And I suspect that the code needed already exists in Mask: From File.

@kagsundaram

The Mask: Simple Shape would be so much more wonderful than it already is if it had an Invert Checkbox as Mask: From File does.
