    /***
     * Introduction:
     *
     * Algorithms created with GEGL are expressed as graphs of nodes. The nodes
     * have associated image processing operations. A node has output and input
     * pads which can be connected. By connecting these nodes in chains a set of
     * image operation filters and combinators can be applied to the image data.
     *
     * To make GEGL process data you request a rectangular region of a node's
     * output pad to be rendered into a provided linear buffer of any (supported
     * by babl) pixel format. GEGL uses information provided by the nodes to
     * determine the smallest buffers needed at each stage of processing.
