I thought that was what the scroller was supposed to do for you, at least if
you actually optimized drawing to use the "rect" in drawRect, which is what
I am currently trying to do.
I may have something else going on. The version in the app store works
fine, but my current one is now crashing all over the place, even though
(for testing) I went back to native tile size and no optimized drawing.
Unfortunately, running out of memory, the stack trace leads back to the run
loop and provides nothing useful.
