 * This is an alternative class for particle systems. It is responsible for storing a
 * set of particles with each having an x- and y-coordinate the number of the
 * layer where it should be drawn and a texture.
 * This version of the particle system class doesn't use virtual screen coordinates,
 * but Interactive ones. Particle systems which need Interactive levels coordinates, such
 * as rain, should be implemented here.
 * Classes that implement a particle system should subclass from this class,
 * initialize particles in the constructor and move them in the simulate
 * function.
