1. A computer-implemented method for rendering a graphics image, the method comprising: identifying a first set of samples that reside within a pixel, wherein each sample in the first set of samples is associated with one or more state values; determining coverage of the first set of samples relative to a graphics primitive; reducing the first set of samples to a second set of samples, wherein the second set of samples includes fewer samples than the first set of samples; and determining a color value for each sample in the second set of samples based on the coverage of the first set of samples relative to the graphics primitive and a color value associated with the graphics primitive.
