anchor: RandomGenerator:getState
  Gets the current state of the random number generator. This returns an opaque string which is only useful for later use with RandomGenerator:setState in the same major version of LÖVE.
  
  This is different from RandomGenerator:getSeed in that getState gets the RandomGenerator's current state, whereas getSeed gets the previously set seed number.
  state = RandomGenerator:getState()
  state string The current state of the RandomGenerator object, represented as a string.
