## Link to GitHub Issue or related Pull Request, if one exists n/a ## Description of change Create three distinct layers for the overlay: 1. Bottommost persistent layer - non-interactable layer that is always on. This was only for notifications, but now the FPS widget lives here as well. 2. Overlay windows layer - most interactable windows go here. 3. Topmost main menu - this is reserved for the main menu (escape key) and this is a modal dialog that occludes the layers below. Why? - `toggle overlay` behavior with FPS widget *also* toggling on/off was a bit confusing (now they're two separate keys) - FPS widget is popular, but it caused the entire overlay to be active, which affects how input is handled - the main menu being a standalone window was a little awkward (now it's a modal) ## Testing
