CIImage slower than NSImage?

Hi All.

I am using CoreImage in my application, and I'm finding that geometric operations, particularly rotation, are much slower with CIImage than NSImage. In fact, rotating an NSImage causes no noticeable slowdown while rotating a CIImage causes a very noticeable slowdown.

Also, applying a transform to a CIImage as a filter yields different results than when the transform is applied to the current graphics context.

Can someone shed some light on this?

Thanks!

-Kenny
