[Feature]: Allow GM to Lock Overlays.

[FullBleed]

Feature Request

A GM might want to use the overlay feature to display somethings on a client that they don't want the client to be able to toggle off.

The Solution you'd like

For overlay function consistency (i.e. setOverlayVisible) a setOverlyLock() function would probably do the trick:

Usage

setOverlayLock(name, visible)

Parameters

name - Overlay name.
lock - A 1 or 0 to lock the overlay visibility toggle in the Windows>Overlays navigation menu.

Alternatives that you've considered.

No response

Additional Context

My use-case for this was to be able to slowly darken a player's screen due to certain events. It's a great effect, but if players can toggle the overlay on and off at will they can subvert it (like giving them a toggle switch for FoW.)
