    [Nicosia] Images with translate-Z get unloaded when out of view

    Reviewed by Miguel Gomez.

    We pass a nullptr image backing store to the compositor to indicate to
    use the current image when the layer is visible. When the layer becomes
    invisible, the layer contents is set to nullptr, but when it becomes
    visible again, we don't update the image backing store in the update,
    because the native image didn't change. When the layer becomes visible
    we always need to set the image backing store again to make sure the
    compositor updates the layer contents.
