    cogl-path: Clear the stroke attribute buffer when modifying the path
    
    Commit 12b3d21a changed cogl-path so that it will use the vertex
    attribute API to stroke the path in a similar way to how it was using
    the API to fill the path. However it wasn't clearing the stroke buffer
    when the path is modified so it would continue to use the unmodified
    stroke.
