    main: don't show stage until still frames are loaded
    
    We sometimes map the stage before we've loaded a background on it
    because of a race asynchronously loading the session mode.
    
    This manifests as the startup animating starting over a white
    background.
    
    This commit defers showing the stage until after the still frames
    are loaded.
