I've not seen that personally, though setAspectRatio suffers from such 
a fate (since it includes the title bar in the aspect ratio, making it 
basically useless).

Since you needed pixel multiples, you'd also need to use 
setContentResizeIncrements:

There may be a bug that the zooming doesn't use 
setContentResizeIncrements (I've never needed that functionality) but 
from what I remember, setAspectRatio worked fine with zooming.
