Because there may be very long key, such as space bar on tablet, we
should not use the distance between the touch point and the center of
key as proximity detection. Instead of that, this change uses the
distance between the point and the nearest edge of key as proximity
detection.
Also this change fixes the bug that space key (code 32) was not
counted in proximity detection.
