    Also increments {plate_ct} for each plate found. The caller
    must initialize that counter. The value of that counter will be used
    as the plate index for {sheet_cut_write_plate}.
    
    As a side effect, all nodes that descend from {pc} will be actually
    flipped when appropriate, and all fields {.sub_flip} will then be
    set to {FALSE}, before writing any plates out. Assumes that {pc}
    itself does not need flipping.
    
    This procedure is usually called with {pc} being the root block of a
    stock sheet, and {org_pc} being the coordinates of the low corner of
    the usable area of the sheet. */
