Chris@0 22 * This is a view that displays dense 3-D data (time, some sort of
Chris@0 23 * binned y-axis range, value) as a colour plot with value mapped to
Chris@0 24 * colour range. Its source is a DenseThreeDimensionalModel.
Chris@0 25 *
Chris@0 26 * This was the original implementation for the spectrogram view, but
Chris@0 27 * it was replaced with a more efficient implementation that derived
Chris@0 28 * the spectrogram itself from a DenseTimeValueModel instead of using
Chris@0 29 * a three-dimensional model. This class is retained in case it
Chris@0 30 * becomes useful, but it will probably need some cleaning up if it's
Chris@0 31 * ever actually used.
