@patrick_h_lauke Do these working definitions sound right to you?
Path-based gestures are dragging movements where the path is significant.
Sliding is the same as dragging movement.
Swiping is either a directional dragging movement where a gesture is recognized after the pointer has moved a minimum distance, or, a directional gesture that's only recognized on the pointer-up event (or both).
Flicking or Flinging is a directional gesture that's only recognized on the pointer-up event.
