Hi Jeff,
thanks for writing http://iphonedevelopment.blogspot.com/2008/04/web-services-fun_18.html
It is a very good writeup of many of the things we've discussed. :-)
What's very relevant to our discussion is the fact that you don't
mention having to delete half of the generated code.
Try offsetting the final result by 0.5, so that you draw the actual
pixel, not anti-alias across two.
