This might be overkill, but if we want to optimize this function we could just do a temporal_copy and then overwrite all temptype values in a single loop. This works, because the memory representation of true / false is the same as 1 / 0 (at least should be, not sure about endianness problems).

Ah nvm, we still need to change the bbox type. This optimization is probably not worth the effort and maintenance cost.
