    sourceview: enable search bubbles within limited scope
    
    We want to control what scaling these are rendered at because otherwise
    they just don't make much sense. Also, they get harder to render the
    right rounded corners unless we switch to doing that drawing without the
    GtkSnapshot helpers.
