comparison layer/WaveformLayer.h @ 44:ad214997dddb

* Refactor Layer classes so as no longer to store a single View pointer;
  instead they need to be able to draw themselves on any View on demand.
  Layers with caches (e.g. spectrogram) will need to be further refactored
  so as to maintain a per-View cache

* Begin refactoring MainWindow by pulling out the document stuff (set of
  layers, models etc) into a Document class.  Not yet in use.

This revision is fairly unstable.
