38 * This is the base class for particle systems. It is responsible for storing a
39 * set of particles with each having an x- and y-coordinate the number of the
40 * layer where it should be drawn and a texture.
41 * The coordinate system used here is a virtual one. It would be a bad idea to
42 * populate whole levels with particles. So we're using a virtual rectangle
43 * here that is tiled onto the level when drawing. This rect.has the size
44 * (virtual_width, virtual_height). We're using modulo on the particle
45 * coordinates, so when a particle leaves left, it'll reenter at the right
48 * Classes that implement a particle system should subclass from this class,
49 * initialize particles in the constructor and move them in the simulate
