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