[Image-SIG] Antialias, Bicubic resampling not working...

[Justin Fagnani-Bell]

So the mode was P and converting to RGB fixed the thumbnail issue,  
but it didn't fix the rotate problem. It very noticeable, because I'm  
using expand=True with a white background test image, and the edges  
are very jagged.
I'm saving as a PNG, and there's pretty much nothing going on other  
than a thumbnail and rotate.

Any other ideas?

Thanks a lot,
   Justin
