Class containing the information necessary to Linearly Interpolate a ParticleEmitter's position and orientation between Updates when adding many particles.
The Emitter's Current Orientation.
The Emitter's Current Position.
How many seconds have elapsed since the last Update, so we know how much to linearly interpolate the Emitter's Position and Orientation.
The Emitter's Previous Orientation (i.e. orientation at last Update).
The Emitter's Previous Position (i.e. position at last Update).
