Note: This property is only valid when the TouchImageRotationEnabled property is set to true.

This property determines what angles will trigger a rotation of the current image during a rotation gesture. For instance, if this property were set to 30° then when the user rotated greater than 30°, the image would rotate 90°. If the user rotated back below 30°, the image would rotate back the 90°. With 30° as an example, think of each place a rotation could occur as the numbers on a clock. If the user passed his fingers from the 12 o'clock position to across the 1 o'clock position, the image would rotate 90° clockwise. If the user went backwards so that his fingers crossed the 1 o'clock position towards the 12 o'clock position then the image would rotate back 90° counter-clockwise when the user's fingers had passed on the other side of the 1 o'clock position. If this behavior is not desired, then the application can either set this value to 90.0° or set the TouchImageRotationEnabled property to false and handle the TouchRotationGestureOccurring and TouchRotationGestureOccurred events.
