    app: crop input to output rect in channel ops
    
    In gimp_gegl_apply_{border,grow,shrink,flood}(), which are used
    by the corresponding channel functions, pass crop_input = TRUE to
    gimp_gegl_apply_operation(), to clip the input to the output rect.
    
    These operations process the entire input in one go, regardless of
    the requested output region; however, the channel functions
    calculate the output region according to the known channel bounds,
    hence clipping the input to these bounds doesn't affect discard any
    information, while avoiding unnecessary work.  In particular, this
    makes the corresponding operations on small selections in big images
    much faster.
