Returns the rotation angle, in degrees, of the contact area ellipse defined by
Touch.radiusY. The value may be between 0 and 90. Together, these three values describe an ellipse that approximates the size and shape of the area of contact between the user and the screen. This may be a relatively large ellipse representing the contact between a fingertip and the screen or a small area representing the tip of a stylus, for example.
Note: This attribute has not been formally standardized. It is specified in the Touch Events – Level 2 Draft specification and not in Touch Events Recommendation. This attribute is not widely implemented.
var angle = touchItem.rotationAngle;
The Touch.radiusX example includes an example of this property's usage.
