Get / Set how fast the Particle System Simulations should run.
Example: 1.0 = normal speed, 0.5 = half speed, 2.0 = double speed.
NOTE: This sets the SimulationSpeed property of each individual Particle System in this Manager to the given value. It will also set a particle system's Simulation Speed when the particle system is re-initialized, and when a new Particle System is added to the Manager in the future.
NOTE: Setting this property only has an effect if the SimulationSpeedIsEnabled property is true.
NOTE: This will be set to zero if a negative value is specified.
