Changes

[jacobp100]

Sets the minimum distance to 0, so fine adjustments are possible

Makes the selectUpper/selectLower gestures simultaneous so they won't delay the dragging. There might need to be some logic here to revert to the previous value if they tapped but slightly moved their thumb

Refactors some (Horizontal{Value,Range}Sliders) to use @GestureState - which properly tracks when gestures are cancelled (which onEnd does not do). The others need updating, but I'm lazy

Fixes simultaneous gestures when using interactive track, and putting a finger on the thumb and track

Adds precisionScrubbing which lets you move your finger down to slow down the scrubbing speed:-

enum ScrubbingSpeed: Float {
  case normal = 1, slow = 2
}

struct Example: View {
  var body: some View {
    yourSlider.precisionScrubbing { offset -> ScrubbingSpeed in
      if (abs(offset) > 200) {
        return .slow
      } else {
        return .normal
      }
    } onChange: { newSpeed in
      print(newSpeed) // Maybe add to the UI, play some haptics or something
    }
  }
}

It may look like extra ceremony declaring an enum for scrubbing speeds - and you may think you could just return a float. However - it's absolutely critical that there are a limited number of values returned for the scrubbing speed. When going from a slower to faster scrubbing speed (e.g. 8x slow down to 4x), you have to 'undo' the 8x adjustments, and apply them to the 4x. This is what happens in the iOS video player (although they managed to animate this change). This basically means storing every speed and the corresponding offset accumulations in a dictionary, and if the user could freely return any float, and they may be tempted to use linear interpolation for the speed, which would make the dictionary huge

Thank you for sharing the bug fix for the drag delay. I hope it gets merged one day.
