Inconsistent trimmer view behavior:
1. When it is at min range most right, grabbing the right handle results in scrolling
2. When it is at min range most left, grabbing the left handler results in no action.
Moreover, when the trimmer view is dragged to the most left, you can see some adjustments of it and chart scrolling by 1pt. Also it cancels the touches there and you have to release the finger and put it back in order to start scrolling again.
Just experiment with it in the most left position, you will notice what i am talking about.
