  @param pParam the image read parameter, or {@code null}
  @return true if {@code pParam} is non-{@code null} and either its {@code getDestination},
  {@code getDestinationType} returns a non-{@code null} value,
  or {@code getDestinationOffset} returns a {@link Point} that is not the upper left corner {@code (0, 0)}.
