Chris@0:  * This is a view that displays dense 3-D data (time, some sort of
Chris@0:  * binned y-axis range, value) as a colour plot with value mapped to
Chris@0:  * colour range.  Its source is a DenseThreeDimensionalModel.
Chris@0:  *
Chris@0:  * This was the original implementation for the spectrogram view, but
Chris@0:  * it was replaced with a more efficient implementation that derived
Chris@0:  * the spectrogram itself from a DenseTimeValueModel instead of using
Chris@0:  * a three-dimensional model.  This class is retained in case it
Chris@0:  * becomes useful, but it will probably need some cleaning up if it's
Chris@0:  * ever actually used.
