There isn't any image data in a CIImage, it's a list of operations
to be performed when drawing. In order to get image data you have
to render it.
Does this mean that the only place the image data is accessible is
from the NSView that it's been rendered into? I don't see how to
obtain this from the view.
In this case a CG bitmap context would probably be what you want.
Once rendered, how do you associate a CG bitmap context with it?
