    gegl: move back 'valid_have_rect = TRUE' in gegl_node_get_bounding_box
    
    though, now child->have_rect is used in gegl_operation_set_need_rect
    (gegl-operations.c) even when child->valid_have_rect is FALSE.
    
    But otherwise generating gegl:photocopy example image ended in
    infinite loop or deadlock
