Title: Develop3d - Adds gesture support using WinRT gestures.

WinRT provides a comprehensive gesture recognizer that provides nearly everything we need.

Pinch in XNA provides positions and deltas of both touch locations. WinRT only provides the centre position and change in distance between the two touch locations for the pinch gesture. I am placing the centre position in GestureSample.Position and GestureSample.Delta is Vector2(Expansion, 0). Position2 and Delta2 are set to zero.

If this is not suitable, we may have to port the iOS gesture code and see if that works better.
