  (still need to batch up multiple sets on the same property)
* Fix failure of spectrogram to refresh when initial part became visible
* Some fixes & paint optimisations in View &c
* Make curve mode for time value layers work properly when resolution == 1
* Some vague improvements for time value layer vertical scale
