    base-item: Re-create the processor before processing an item
    
    Currently, we only create the processor when loading the GeglBuffer for
    an item and keep re-using it forever. However, subsequent changes to
    the pipeline can change the bounding box of the graph without the
    processor knowing about it.
    
    Therefore, let's create a new processor before processing so that it
    has the bounding box for the current state of the pipeline.
