    stage-impl: Use onscreen framebuffer for scanout
    
    We may want to use scanout even if the default framebuffer
    of the stage view is an offscreen, for example when a Wayland
    client provides pre-rotated buffers. The caller is responsible
    to ensure this is correct - we already asserted on that before.
