I needed a way to smoothly hide/reveal the mask effect with animation and mask.strength (for crt) wont allow to completely remove the effect from screen even with very high values. So I've added 'fade' to achieve that.

@gavlig fyi added a follow up to this, perhaps it's possible to normalize the values. Then we'd have both strength and fade in a combined value (maybe).
