/* Then we have width*height BCD cells, which corresponds to the real parts,
 * grouped by height.
 *
 * If at least one of the cells has an imaginary part (highest bit of the
 * first nibble set), it is followed by a list of the imaginary parts, that
 * has the same size that the real parts list, that is grouped the same way
 * and that contains actual things (and not crap) only if the complex bit
 * is set on the real part.
 *
 * Notice that imaginary parts in cells files require at least
 * CASIOWIN 2.00. */
