view layer/Layer.cpp @ 224:9465b5375235

* Fix #1672407 confused by plugin-named files in cwd (or home?)
* Fix #1491848 crash when loading new file while transform plugin runs
* Fix #1502287 Background remains black after spectrogram layer deleted
* Fix #1604477 Replacing the main audio file silences secondary audio file
* Fix failure to initialise property box layout to last preference on startup
* Fix resample/wrong-rate display in Pane, ensure that right rate is chosen
  if all current models have an acceptable rate even if previous main model
  had a different one
* Fix "global zoom" broken in previous commit
* Some fixes to spectrogram cache area updating (makes spectrogram appear
  more quickly, previously it had a tendency to refresh with empty space)
* Fixes to colour 3d plot normalization
