    In gegl_buffer_create_sub_buffer(), always return a new buffer
    object, even when the requested extent is equal to the input

    This makes sure that (non-content-related) changes to the original
    buffer don't affect the sub-buffer.
    Adapt operations that use gegl_buffer_create_sub_buffer(), and for
    which this distinction is irrelevant, to explicitly ref the
    origianl buffer when the bounds are equal, instead of creating a
