Thanks for the file. Could you post a screenshot of the result so I wouldn't
have to reproduce it? 
I agree there can be a behaviour you don't expect, but I'd say that using
resampling to simulate gradients is kinda insaine. :)
Resampling is expensive by definition. It's much faster to use a small image
and zoom it in with a bilinear filter.
