  Yes, but if the previous pixel was antialiased, its color will differ
from the next pixel no matter where does the ray hit the plane in this
next pixel. The color of the previous pixel is a mix between the light and
dark colors of the plane, and thus is very different from either.
  This would mean that if the pixel at the left of each row is antialiased,
all the pixels in that row should be antialiased as well (because each time
a pixel is antialiased its color will differ radically from the next pixel
regardless of where does the ray hit).
  This is what I don't understand.
