Anyway, I did find a post on this list that mentions a similar
problem (http://www.cocoabuilder.com/archive/message/cocoa/2008/12/13/225352
). However, in my case I am not applying any transforms to the layer
hierarchy, and I am also ensuring that the frame origin of each
object is drawn at a "whole number" point (both of these things are
mentioned as potential causes in that thread).
Your suffering from the same problem as above. The frame origin is not
what matters, but rather the layer's position (all aspects of the
frame are synthesized from other properties of the layer). Depending
on if your layer's dimensions are odd or even the position should be
on the pixel or on the half pixel to avoid antialiasing like this.
