Is it possible to have HDR output with 3.6 ? I couldn't find anything 
about this in the doc...
Because given HDR output, the problem could be solved by post-processing 
it, for example simulating somehow the bleeding of bright area, etc...
This is not necessarily the task of the raytracer, and could be 
impplemented in a separate program.

As I understand it, the whole problem here seems to be that some 
consider antialiasing as a kind of post-process aimed at removing 
jaggies in the image, while other think of it as an integration method 
that has no sense on clipped values...
