I didn't say it should only be in Ansel, and I don't think so. I just  
think that this is the sort of thing if we put it right into the  
Horde_Image:: api it results in an unmanageable API. That's why I  
think it should be in a Decorator or Plugin or something - provided  
with Horde_Image, packaged, but not on the same level as line(),  
text(), etc...
