it could cycle between discretized colors with a weighting depending on how close the
actual color is to each. (for graded colors, it's slightly more complicated). This
can't be done post-processing, by which point the precision has already been lost.
The floating point values of each color component of each pixel will,
obviously, be available to the post-processing filter.
