/// Audio channel positions.
///
/// These are the channels defined in SMPTE 2036-2-2008
/// Table 1 for 22.2 audio systems with the Surround and Wide channels from
/// DTS Coherent Acoustics (v.1.3.1) and 10.2 and 7.1 layouts. In the caps the
/// actual channel layout is expressed with a channel count and a channel mask,
/// which describes the existing channels. The positions in the bit mask correspond
/// to the enum values.
/// For negotiation it is allowed to have more bits set in the channel mask than
/// the number of channels to specify the allowed channel positions but this is
/// not allowed in negotiated caps. It is not allowed in any situation other
/// than the one mentioned below to have less bits set in the channel mask than
/// the number of channels.
///
/// `AudioChannelPosition::Mono` can only be used with a single mono channel that
/// has no direction information and would be mixed into all directional channels.
/// This is expressed in caps by having a single channel and no channel mask.
///
/// `AudioChannelPosition::None` can only be used if all channels have this position.
/// This is expressed in caps by having a channel mask with no bits set.
///
/// As another special case it is allowed to have two channels without a channel mask.
/// This implicitely means that this is a stereo stream with a front left and front right
/// channel.
