* Add Thumbwheel widget for all our zooming needs * Use QSettings to save/restore window size and position -- precursor to switching our preferences to QSettings as well -- wish I'd noticed it sooner * Only suspend writes (not reads from the underlying cache objects) from the fft caches when repainting the spectrogram -- performance should now be significantly better
