   I think the original spirit of the competition always allowed that kind of
  layer-rendering, even if the original authors of the rules never thought on
this possibility. It was just some of the judges and entrants who thought
this was forbidden, but for me it is clear that anything affecting equally
all pixels was legal. Fortunately, I've a copy of the Rules and FAQ, and
specially the FAQ seems very clear to me:

> [1.1.11] Exactly what do you mean by "post-processing"? That means
> running any image-manipulation program on the image after it is rendered.

   In any case, to make it really clear that it is allowed, the new FAQ could
use an entry very similar to this old one, just replacing "parts" by "layers":

> [1.1.15] How about rendering my image in two / three / twenty-six parts
