buf

uint8_t* LifeContext::buf[2]

The two grid state buffers.

A 0xFF (ALIVE_CELL) value means the cell is alive (or new born), while the decreasing values from 0xFE to 0 means the cell is dead; the range of values is used for the slow death effect, or mold (0xFE means dead, 0xFD means very dead, 0xFC means very very dead... and 0x00 means definitely dead/mold).
