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.

Check whether the processor is alive with respect to start time and life duration. Note that this method may return true even if the processor has been disabled by calling setEnabled(false). To test whether the processor is actually processing particles or not, you should evaluate (isEnabled() && isAlive()).
