    Bug 786992 - removing alpha produces a black image (sometimes), with OpenCL · 66bb469a
    Ell authored
    When creating a flatten node, which is used when removing alpha
    channels and when flattening an image, use a gimp:normal node to
    combine the layer with the background color, instead of a gegl:over
    node.  gegl:over can apparently result in completely black output
    with OpenCL enabled, under certain (not fully pinned-down)
    conditions.
    
    As long as the OpenCL version of gegl:over is borked, there is not
    much reason to use it over gimp:normal, which is more consistent
    (in intension, if not in extension) with the rest of the
    compositing pipeline.
