Keep in mind that the overall media intensity is dependant on the size of 
its container object and I'm not applying the media to a unit box.

If I double the intensity of the media then I can get the sunbeam effect 
that this scene seems to need, but only at the expense of the sky turning 
indigo.  I can compensate for the darkened sky by doubling the intensity of 
the sun, but then I have massive problems with artifacts.

The basic method seems to be to leave samples and intervals alone and do 
all artifact removal with aa_levels and aa_threshold.

I've found method 2 easiest to work with as it produces non-grainy images 
much, much faster than is possible with method 1.
