Just curious, what kind of speed are you getting with the CIImage
methods? I saw the usefulness of generating random images for my own
purposes and polished the posted code a bit today. It was generating
100 million pixel images (10,000 x 10,000) with per-pixel
randomization in about 2.2 seconds. What kinds of times are you
getting for comparable images using the CIImage methods?
A quick test on a 2GHz iMac takes at least twice as long 4.5 seconds
to generate a 10,000 X 10,000 CGLayer of noise.

I've got the random noise part working and it easily fast enough.
Its a shame there isn't a way to specify the opacity when drawing
CGLayers. I'd find that useful but I imagine there is a reason for
it.
