[gnome-photos/wip/rishi/double-buffering: 2/12] base-item, utils: Rename a function



commit a46bd5f631feee3f2224082cb89c5814a7ab8c47

    base-item, utils: Rename a function
    
    Currently photos_utils_get_buffer_from_node hits a fast path inside
    gegl:buffer-sink and doesn't actually create a new GeglBuffer. It
    returns a new reference on the GeglNode's output buffer.
    
    To implement double buffering inside PhotosImageView, we will add a
    similar function that will actually copy the GeglBuffer. This rename is
    meant to clarify the difference between the two.
