/**
* A `Boolean` that specifies if the `Engine.run` game loop should use a fixed timestep (otherwise it is variable).
* A `Boolean` that specifies if the runner should use a fixed timestep (otherwise it is variable).
* If timing is fixed, then the apparent simulation speed will change depending on the frame rate (but behaviour will be deterministic).
* If the timing is variable, then the apparent simulation speed will be constant (approximately, but at the cost of determininism).
