// Usually the player would touch the trigger first and then the trigger would touch the player later on in the same frame.
// The trigger touching the player would fix up the touchStamp (which was increased by 1 by the trigger physics simulate)
// But since we're blocking the trigger from ever touching a player outside of here we need to manually increase it by 1 up front
// so the correct +1'd touchStamp is stored in the touchlink.
// After simulating the players we restore the old touchStamp (-1) and when the entity is simulated it will increase it again by 1
// Thus both touchlinks will have the correct touchStamp value.
