Remarks
Returns a scaled value of the approximate size for the given pointer <em>index</em> (use #getPointerId(int) to find the pointer identifier for this index). This represents some approximation of the area of the screen being pressed; the actual value in pixels corresponding to the touch is normalized with the device specific range of values and scaled to a value between 0 and 1. The value of size can be used to determine fat touch events.
