First cut at a scratch demo in Swift. Can advance and rewind tracks with the knob (at 33 RPM). Would be nice to have the music player simply track the gesture while the touch is down (scratching). Not to mention there will be an Objective-C demo too.
Fix #16. This has bothered me for a while. I'm glad to see this bug die.
Refactoring, comments, yadda.
Fix #17: Knob control no longer generates a .ValueChanged event when set programmatically.
Better images, including disabled ones. Corrections, comments. Yadda.
