Correctly samples just around the navigation bar handle

The sample rect is 10dp left and right to the handle while taking full
size of the current navigation bar inset. Also changed the threshold to
pass the median luminance of 0.5f while only applying the color change
if the luminance change is above 0.05f. Also shrunk the width of the
navigation bar handle.
