Well, if the antialiasing algorithm simply computes the integral of the 
unclipped values, it is possible for a pixel only partially covering a 
bright area of the scene to be pushed over 100%. If the area of the 
scene has an intensity of 10, it need only cover 10% of the pixel to 
reach maximum intensity. Digital cameras have imperfect optics, blooming 
effects, a different detector element geometry...each pixel is usually 4 
squares: a red, two green, and a blue...and various software filters. I 
think this is something that should be taken care of with a post-process 
filter...it wouldn't be a problem if display devices could reproduce the 
true intensities.
