[Bf-cycles] GSoC - Spectral Rendering

[Gavin Howard]

      All,

     Based on recommendations from Ton and Brecht, I have decided to apply
for Google Summer of Code under the Deformation Motion Blur project. I have
completed a rough draft of my proposal on my user page at
http://wiki.blender.org/index.php/User:Gdh. If possible, please look at the
proposal. Also, I would be very much appreciative if the proposal could be
discussed during the developers' meeting on IRC this Sunday. I know that
this is very soon before the meeting, so if it cannot be discussed, that is
absolutely fine, but please take a look when you get the chance. Thank you.

     God Bless,
     Gavin Howard
