Detailed Description

A common base interface for those classes which need to do something on particles.

Such classes are, for example, Emitter (particle generation) and Program (particle animation). This class holds some properties, like a reference frame and a reference to a ParticleSystem; descendant classes should process the particles taking into account the reference frame, computing the right transformations when needed.
