[Bf-cycles] GSoC - Spectral Rendering

In order to help those concerned with development, as well as users,
make a decision, I have posted a pros and cons list for each of my top
three choices, which are Spectral Rendering, Volumetric Rendering, and
Deformation Motion Blur. It is on my user page at
http://wiki.blender.org/index.php/User:Gdh. I have ranked them according to
my preferences in this order:
1. Volumetric Rendering
2. Deformation Motion Blur
3. Spectral Rendering
Before you write back asking my reasons for choosing that order,
please go read my user page at the link above. I tried to explain all of my
reasoning. If anything is unclear, or you simply don't like my rankings,
let me know, especially if your name is Brecht or Ton. ;) If you would
like, please submit your own ranking, or even better, suggest other choices
that might seem plausible for *my skill level*.* *Thanks!
