PSCN to turn on, NSCN to turn off, INST to reverse.
Differences from jacob1's commit include: flood fill function that
includes 1px diagonal pipes, powered/reversed state stored in tmp
instead of flags, sparks from PSCN/NSCN/INST always take effect the
following frame, single pixel pipe directions are a number from 0 to 7
so "if(coords)" does not check whether one is set (store another
"transfers according to 1px pipe direction" bit for reverse flow).
