I was confused about the gpiod_flags values and thought that GPIOD_OUT_LOW and GPIOD_OUT_HIGH set the line to be active low / active high. This is not true, but I got the misconception because the flags GPIOD_OUT_*_OPEN_DRAIN do change line configuration and there's a subchapter about *active low* and *open drain* semantics. Add an explicit mention that the initial value is a logical value (and not the line configuration or physical line level). Also add a mention of the function gpiod_toggle_active_low which was previously missing from this document.
