/** @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.
