Parameters
- point1 
 Type: Microsoft.VisualStudio.TestTools.UITest.Input.Point- A point on screen at which user places one of two fingers to perform a pinch gesture. 
- point2 
 Type: Microsoft.VisualStudio.TestTools.UITest.Input.Point- A point on screen at which user places the second finger to perform a pinch gesture. 
- distanceToMove 
 Type: UInt32- The distance each finger moves toward each other in pixels. 
Remarks
Playback of a pinch gesture depends on screen resolution. If the resolution changes, the parameters may have to be changed.
