double size

The area of the screen being pressed, scaled to a value between 0 and 1. The value of size can be used to determine fat touch events. This value is only set on Android, and is a device specific approximation within the range of detectable values. So, for example, the value of 0.1 could mean a touch with the tip of the finger, 0.2 a touch with full finger, and 0.3 the full palm.
