'convert -average *.png result.png' for you Unix/Linux-types.  (Upon further
inspection, of course ImageMagick is available for Windows, too.)  I'm not sure
how it handles precision for many images, but I've had good luck.  I'd also
recommend rendering much larger images than you need since you can just
down-scale later and reduce the noise.  2x2 -> 1x1 = 1/sqrt(4) = 1/2 the noise.
