 From the man page, this new feature completely replaces pdfblur. So 
there's no need to render multiple images and average them together? I 
haven't seen any other mention of this new feature. Does rpict simply trace 
multiple rays for the one pixel?

Does it adapt e.g points in focus only require a few rays, but points out 
of focus require more rays over the area of confusion (or whatever it's 
called) ?
That would improve the efficiency/speed over the laborious pdfblur method.

Oh, and thanks to everyone involved in the development of Radiance. It's 
amazing!
