2020-04-09 Chris Cannam Unify various vectors to our base floatvec_t type; store columns in fft model cache at their desired height so we can return a reference (speeding up the peak-frequency spectrogram in particular)
2017-02-28 Chris Cannam Add Range01 normalisation method to ColumnOp. This is the normalisation that is actually used in the Colour 3D Plot layer historically when column normalisation is enabled (not Max1 after all).
