+/** @class AudioMappingView
+ *  @brief This class displays the mapping of one set of audio channels to another,
+ *  with gain values on each node of the map.
+ *
+ *  The AudioMapping passed to set() describes the actual channel mapping,
+ *  and the names passed to set_input_channels() and set_output_channels() are
+ *  used to label the rows and columns.
+ *
+ *  The display's row count is equal to the AudioMapping's input channel count,
+ *  and the column count is equal to the number of name passed to
+ *  set_output_channels().  Any other output channels in the AudioMapping are
+ *  hidden from view.  Thus input channels are never hidden but output channels
+ *  might be.
