Subject: [PATCH 1/2] added code to flatten chunks for infinite maps. Please
 note that I did not remove all code that works with chunks, but I set chunks
 to nil after copying the data so the majority of that code should never run.

Subject: [PATCH 2/2] I discovered another error where chunked maps might come
 up with errors if they have chunk rows that are do not have tiles in them, so
 I added an if statement that prevents it from crashing and returns the
 correct nil values.
