    source-view: handle missing clip rectangle
    
    We were hitting an assertion here recently, due to no clip rectangle.
    Instead, avoid fetching the clip rectangle twice, and compute the
    buffer_x and buffer_y externally.
    
    If we fail to get a clip rectangle, use the widget allocation instead.
