<BLOCKQUOTE>A common base interface for those classes which need to do something on particles. Such classes
are, for example, <CODE>Emitter</CODE> (particle generation) and <CODE>Program</CODE> (particle animation).
This class holds some properties, like a <I>reference frame</I> and a reference to a <CODE>ParticleSystem<CODE>;
descendant classes should process the particles taking into account the reference frame, computing the right
transformations when needed.</BLOCKQUOTE>

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()).
