In MSDN document, the Pinch gesture states: Two or more fingers touch the screen and move closer together or farther apart. But there's also a Stretch gesture:
Two or more fingers touch the screen and move farther apart.
Pinch has already contains Stretch, why there's a Stretch exist?
Technically pinch is supposed to be only closer together...one method may contain the info needed to make it work for both gestures though & or they may be able to be called separately based on whether you need to zoom in or out which was the whole purpose
I don't have a touch screen myself because my standards are high, I want a 3d(active 3d glasses, nvidia), touch capable, 1080p resolution(monitor) (multiple hdmi inputs a plus)which is why I haven't got a new monitor from one I use that's 1920*1200 resolution
