comparison layer/NoteLayer.cpp @ 99:453f7da3534e

* Fix serious failure to reload "imported" (i.e. all non-derived non-main)
  models from .sv file
* Give a short playback duration to notes with formal duration of 0 or 1
* Show crosshairs on spectrogram even when there is another layer on top
  (if it isn't opaque)
* Always paste to the same time in the layer as the cut/copy was from, rather
  than to the playback pointer -- less flexible, but more predictable and
  less annoying.  We probably need a way to get the old behaviour if pasting
  from somewhere else in the future (e.g. from a text file), but we can't do
  that yet anyway
* Use a compound operation for dragging and resizing selections, so as to
  ensure a single undo operation works
* Use a note model as the target for feature extraction plugins that output
  variable samplerate data with more than one value per feature
* Avoid possible crashes in cut/paste if a layer proves to have no model
