notes:

Good job, on a tough problem set! You had just a few problems:

Shadows weren't working

Transmission (refraction) was not working 

There was a problem with your cone intersections

Jittering was not done quite correctly (you calculated a single jitter
for each pixel, which you reused for every subpixel, whereas you were
supposed to generate a new random jiggle for each pixel AND
subpixel. Not a huge deal, though.)

The problems with transmission, shadowing and cone-intersection would
be a problem, except looking at your code, you definitely seemed to
have the right idea in terms of implementation.
