| True, that is a bug and it's fixed now. Thanks for spotting :-).

Checking greater than 3 still seems a bit un-expandable. Why not
allocate the first 4096 offset values to mean special tiles? Then you
could put special tiles named 0.png to 4095.png somewhere and whenever
those offsets are encountered, redirect to them.
