Mon, 12 Nov 2018 11:34:34 +0000	Chris Cannam	Use log-frequency rather than log-bin for calculating x coord in spectrum. This has the advantage that frequency positions don't move when we change the window size or oversampling ratio, but it does give us an unhelpfully large amount of space for very low frequencies - to be considered spectrogramparam
Thu, 08 Nov 2018 12:55:36 +0000	Chris Cannam	Retrieve only the values already determined to be peaks spectrogramparam
Wed, 07 Nov 2018 11:37:51 +0000	Chris Cannam	Add oversampling option to spectrum as well spectrogramparam
Thu, 18 Oct 2018 13:21:56 +0100	Chris Cannam	Add mechanism for saving/loading colour maps by name/id rather than by numerical index, for future compatibility when adding to or changing the supported colour maps. Add two new colour maps (and one old one). Write out backward-compatible numerical indices for use when reloading in older versions. Also add a mechanism to invert the colour map, though I don't think it turns out useful enough to include in the UI.
Thu, 03 May 2018 15:15:15 +0100	Chris Cannam	Provide linear horizontal scale in spectrum as well as log; fix bin positioning and colour scale property box updating; ensure proper background colour and visibility of peak lines horizontal-scale
Wed, 02 May 2018 14:27:17 +0100	Chris Cannam	Merge horizontal-scale
