Get the current scaled value of the approximate size for the given pointer index that
occurred between this event and the previous motion event.
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.
