What does lock()/unlock() do?
Sorry for such a stupid question  , I always found these method around at draw function but not anywhere else, so what does lock/unlock from Map<> and Image do? Because I can still access lockedData/Key without locking it first.

It locks/unlocks the memory for other threads.

If you lock a Map on one thread, then other threads won't be able to add/remove elements. This is for multi-threading.
Images needs to be locked in order to access their pixels (except software mode which always has full access).
