  I don't think so.
  If the border of the bright object takes one half of the current pixel,
about a half of the samples will hit the object. If the object contributes
10 times more than the other half of the pixel, it will dominate the color
of the pixel with a factor of 10:1 (which means that the other half of
the pixel can diminish the color of the pixel only by 1/10, even though
its area is 1/2 of the pixel).
