Get the current scaled value of the approximate size for the given pointer 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.
