Under Tiger, you can create an NSCIImageRep, and add that to your
NSImage. After that, you can draw as you would any another CIImage.
In terms of getting CIImage to an NSImage, there are some details here:
<http://theocacao.com/document.page/350>
I've found several code snippets than render a CIImage instance
into an
offscreen bitmap, but I've seen non-deterministic results (possibly a
problem with the code I grabbed).
It's probably an issue with that sample. It should work fine.
