In order to do that, I need to set a conditional breakpoint, and this would be easy if an NSRect could be stored in a register, but how do I set a conditional breakpoint when the variable I want to investigate is on the stack? And where would I find each of the CGFloats on the stack?

I usually don't like swizzling; it feels like black magic to me. But since it was just for debugging, this time I put on my blue robe and pointy yellow wizard hat anyway, and found and fixed the problem. Thanks.
