[Bf-committers] compositor defocus node

[Jeroen Bakker]

Hi All,

I have reverse engineered the compositor defocus algorithm to its purest 
form. the result I have posted on my blog.

The current implementation is not depth aware. I am not sure that this 
is a real issue, as nobody complains. I am also not sure about the many 
filter types and settings. the circle has a faster algorithm then the 
rest of the filters, but visually they do not differ much.

Hope it is helpful to you all. Btw I am pleased with the speedup (50% on 
my system). Will try on a GTX200 series next week.

Cheers,
Jeroen
