annotate base/Profiler.h @ 155:ae9be6b6b522
* 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
