While here, can you move these to be above the for-testing functions and group
all of the for testing functions near the end of public:. Also can you add a
comment along the lines of "the rest of the public interface here is used for
testing." Also, maybe we should change our tests to have a FakeTileManager that
promotes protected functions to public, just so this becomes cleaner (this is
unrelated to your patch).

Done.
