Having superbright objects influence their surroundings more than others
would mean, I believe, that ultrabright (>100?) objects would influence
larger and larger areas of the screen, which is not possible with the
current method.

Hmm, talking about color, how's this for an idea (warning: this is
tangential to the thread): store all image data as 64bit integers, with the
range 0-1 fitting in 24 or 32 bits.  Then, adjust the overall brightness of
the scene based on the brightest object?
