I've narrowed down a problem I'm having to the following:
- CIImage built from a rectangle texture
- Translate via -imageByApplyingTransform:
- Run through a CIFilter that does nothing (looks up input, returns)
- Transform again via CIAffineTransform.
- render output to GL
When I render, my texture comes up in all manner of crazy
permutations in my real app (which actually tries to do something
in its filter :).
I should mention that this was on a GF6600 on a 10.4.6 G5.
Running on a MBP, I get a message on the console:

I'd previously tried setting a ROI selector, but it never got
called. Anyway, I think this error message would be useful if it a
reason _why_ it isn't tilable, what I might do about it, etc.
