* 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.
