Apparently, according to wikipedia, the sun's disk has a diameter of around 
0.5 degrees from our point of view. That's equivalent to an area light at a 
distance of 1 unit having a width of 0.0087 units, which is really not very 
much blur. I'm using about 3 times more area_light blur than is realistic.
