So what would you use for for the screen shot? The approximate Gaussian or the true Gaussian? Would this mean that if a better algorithm is used that better approximates natural shadow blurs in half the time of a Gaussian then it isn't allowed? Or that a simple stepped blend with appropriate corner rounding (optimized for a number of steps that were good enough for the size of the e-ink halftone dots it used, say) wouldn't be allowed if it was on hardware optimized to render it that way?
